Comprehensive Management Planning for Lake Owen
2012
Introduction
Comprehensive Lake Planning This project will develop a comprehensive lake management plan for Lake Owenin Bayfield County.  Lake management is based on an understanding of the relationshipbetween the use of the resource andthephysical, chemical, biological and social processes that shapethe lake ecosystem.  To effectively integrate the physical, chemical, biological and social aspects of a lake into a comprehensive plan, a range of information and data arenecessary.  Much of the information and data necessary for the development of a comprehensive lake management plan exists for Lake Owen.  Thus, the primary goals for this proposal are:
1.Synthesize the existing data for Lake Owenrelated to water quality and fisheries.
2.Implement a stakeholder survey to describe the values, uses and behaviors that shape the use and management of Lake Owen.
3.Assess the quality and stressors for nearshore(particularly for aquatic plant communities) and shoreline habitat for Lake Owen.
4.Expand water quality data collection and developa watershed nutrient budget and in-lake aquatic response model for Lake Owen.
5.Initiate astakeholder engagement process to review existing and newly collected data to develop a comprehensive set of lake management goals and management alternativesfor public usage, water quality and biological communitiesthroughout Lake Owen.
Tothis end, this proposal is comprised of a:1) Background section that summarizes the primary uses,current level of scientific understanding and history of management activities throughout Lake Owen; 2) Data Needs and Collection section that summarizes current data gaps/information needsand the proposed methods for data collection;and 3) Management Plan Development section that describes the process of stakeholder involvement and the structure and composition of the resulting lake managementplan.
Background
Lake Use and Users Lake Owen(WBIC Code –2900200)is primarily used as a recreational and fishery resourceby local residents, regional outdoor enthusiastsand Native American First Nations.   Lake Owenhas three public, two undeveloped access pointsand two public beaches(Maps1and 2).  Many residents and riparian owners are actively involved in efforts to understand and protect the health of the lake.  Lake Owenhas an active lake association(the Lake Owen Association; LOA; http://lakeowenassn.mylaketown.com/) thathosts an annuallake association meeting anddistributes quarterly newslettersto lakeshore property ownersto increase awareness and understanding of emerging issuesand ongoing management initiatives.  In addition, the LOAhas received 4DNR grantssince 1997to conduct boat launch monitoring for invasive species(AEPP-102-08 and AEPP-292-11)and collectwater quality data(LPL-964-04).  The LOAhas had volunteerscollect and report water qualityfor Lake Owen through the Citizens Lake Monitoring Network (CLMN) since 1992.

Lake Management Management of Lake Owenis governed by a range oflocal state, federal and tribalregulations.  Many of these rules and regulations are well known among lake users.  However, no comprehensive summary of the applicable regulations currently exists.  Similarly, despite the range of active participants in the management of Lake Owen, no comprehensive set of management goals currently exists(a need that was highlighted in a 2009WDNR report, see the Biological Communities section for more detail).
Lake Characteristicsand Habitat The Lake Owen is a 1323acre,drainage-based lakelocated in southernBayfieldCounty(Map 1).  The lake has a maximum depth of 97 feet, an average depth of 23feet and the lake bottom is comprised primarily of sand,graveland muck.  LakeOwen is likely a dimictic lake, whichstratifies into distinct epilinmion and hypolimnionlayers in June and remixesin September—although these mixing dynamics havenot been confirmed with monitoring data.  Much of the shorelineis developed;however,no comprehensive assessment of shoreline habitat currently exists.  Lake Owen has also been identified as an Outstanding Resource Water (ORW) by the WDNR and this project would support a number of goals identified in the Bayfield County Land and Water Conservation Plan (Bayfield County, 2010; see attached letter of support).
Watershed Description LakeOwenisthe headwaters of the Long Branch of the WhiteRiver,which ultimately drains to Lake Superior through the White and Bad Rivers.A detailed summary of the land use and land cover throughout the Lake Owenwatershed has not been developed, but the area is generally comprised of publicallyowned forested lands with small areas of residential and agricultural lands.  Since Lake Owen is a headwater lake, it is not feed by any major tributaries.
Water Quality Water quality in Lake Owenhas been monitored over differentperiodsand by different agencies since 1992.  All data for this section were accessed through the WDNR Surface Water Information Management System (SWIMS) or the corresponding lake website (http://dnr.wi.gov/lakes/lakepages/LakeDetail.aspx?wbic=2900200).  The most detailed water quality study for the Lake Owen was conducted as part of a WDNR Lake Planning Grant (LPL-964-04) in 2005 (WDNR, 2005).  Results from this study suggested that a significant difference in water quality exist between the northern and southern sectionsof the lake(with southernsections having higher nutrient concentrations) and that water quality had generally degraded over time. Based onthese observations, the authors highlighted the need to identify sources of nutrients potentially affecting the southernbays of the lake.  Water quality in Lake Owen was also described in 1981 as part of Master Degree thesis (Seiser, 1981).
The majority of the recent water quality data havebeen collected through the CLMN.  Through this program, volunteershave collected dataat fourprimarysites since 1992.  Volunteers have generally collected samples once per month from June to September at the deepest points at each of the sampling locations(Map 1).  Water quality measurements have primarily focused onSecchi depth(Figure 1) and, to a lesser extent, total phosphorus in surface waters(Figure 2). Interestingly, although the 2005 WDNR study suggested that water quality was poorer in the southern bays of Lake Owen, the ongoing Secchi (and to some degree nutrient) monitoring as part of theCLMN suggests that surface waters in the northern end of the lake have lower clarify and higher nutrient concentrations.  At this sampling frequency, it will take approximately10years of

continuous monitoring to detecta change in average phosphorusconcentrations of 15% —and 20% for Secchi transparency (summarized in NPS,2008).  As such,the existing monitoring data are well suited to describe long-term water quality trends, but insufficient for describing short-term trends, developing nutrient budgetsor identifying potential sources of water quality pollution.
The combination of the water qualitydata suggests that Lake Owen is alow nutrient lake with average phosphorus concentrations of ~ 11 ug/L, an average Secchi depthof 23 feet, a Secchi Trophic State Index (TSI) of 31.9 and a total phosphorus TSI of 46.5(Table 1).  Lake Owen is currently classified as an oligotrophic lake.  In general, the existingdata suggest that water quality hasdecreased overlast 100 years, butthat current waterquality conditions are relatively stable (Figures 2 and 3).  Despite these relatively stable conditions, one period in the data record (1998-2000) exhibited a significant increase in water clarity.  The cause of this water clarity is unknown, but this event and the significant difference between the Secchi and total phosphorus TSI scores suggest a food-web processes may be an important driver of water clarityin Lake Owen.
Biological Communities The majority of the data that exists to describe the biological communities in Lake Owen isrelated to fisheries.  Fisheries management work in LakeOwenhas been ongoing since the 1930sand is well described in the most recent WDNR fisheries report (Toshner, 2009).  Based on this report, the fish community is highly diverse, consisting of walleye (Sander vitreus), northern pike (Esox Lucius), largemouth bass (Micropterus salmoides), smallmouth bass (M. dolomieui), bluegill (Lepomis macrochirus), pumpkinseed (L. gibbosus), warmouth (L. gulosus), rock bass (Ambloplites rupestris), black crappie (Pomoxis nigromaculatus), yellow perch (Perca flavescens), white sucker (Catostomus commersoni), logperch (Percina caprodes), Iowa darter (Etheostoma exile),bluntnose minnow (Pimephales notatus), central mudminnow (Umbra limi), cisco (Coregonus artedii) and lake whitefish (Coregonus clupeaformis).
The primary fishery management efforts in Lake Owen havefocused on walleye.  Lake Owen has historically had limited native walleye reproduction (likely due to its oligotrophic nature), and this native population has been supplemented by stocking efforts from both state and tribal natural resource agencies.  Despite stocking efforts, walleye remain at low to moderate densities throughout the lake (generally increasing after strong year classes).  Lake Owen has historically had high densities of smallmouth bass.  However, in recent years, smallmouth bass densities have declined andlargemouth bass densities have increased.  Changes in the fishery composition in Lake Owen have significant implications for its long-term management and will be a key element of the resulting management plan.  One ofthe key recommendations of the2009 WDNR study was to develop a lake management plan that would:  “1) develop management objectives for fisheries including goals for densities and size structures for the various fish species found in the lake, 2) develop strategies for protecting and enhancing sensitive aquatic and shoreline habitats, 3) formally establish exotic species survey and control programs targeting satellite infestations, 4) provide educational and participation forum for environmentally sensitive shoreline living, 5) identify uses and user groups to facilitate all recreational uses on the lake, 6) continue water quality monitoring through the self helplake monitoring program.”
Relatively little data exists to describe biological communities in Lake Owen beyond the fishery.  Some work has been done to describe the current and historic plankton assemblages (DNR, 2005); however, no data currently exists to describe nearshore habitat or the aquatic macrophyte communities.

Ecosystem Interactions As described above, arange of different sources of data and information have been developed to describe the health and potential management goals for Lake Owen.  However, all of the existing data werecollected to answer a specific question about one component of the lake ecosystem (e.g., water quality, invasive species…etc.).  As a result, no resources currently exist to describe the relationship between the different elements of the Lake Owen ecosystem.  The most comprehensive management documents developed to date is the 2009WDNR fisheries report(Toshner,2009).  However, in theDNRreport, the authorhighlightsthe needfor a more detailed and comprehensive plan to guide the management of Lake Owen.
Data Needs and Collection Given the scope of current data and ongoing work in Lake Owen,a range of information is necessary to develop a comprehensive lake management plan.  Data and information needs are described below, as well as the collection andanalysis protocols,as they relate to the understanding of physical, chemical, biological and social processes that affect Lake Owen.
Objective 1 –Summarize Lake Uses($2,850) An effective lake management plan is dependent on an understanding how different stakeholders interact with, and affect the lake ecosystem.  This Objective willquantitatively describe the range of perceptions, usesand values that exist for Lake Owenand the drivers of different behaviors that affect the lake ecosystemfor different user groups.  Use, value and behavior will be assessed using a survey research method sent via mail.In an attempt to increase response rate, a modified Dillman method will be utilized(Dillman, 1978), where respondents are contacted prior to receiving their survey as well as sent a reminder after getting the survey.Mail-based data collection will be supplemented with in person interviews at the annual lake association meeting.  Results from this Objective will be used to develop sociological management objectives for Lake Owen as part of the stakeholder process (see Objective 8 for more detail on the stakeholder process).
Objective 2 –Summarize ongoing Lake ManagementWork($1056) To clarify the rules, regulations and agencies that governthe management of Lake Owen,it is necessary to evaluate the ability of the existing management frameworks to effectively achieve the comprehensive lake management goals(development of management goals is described in Objective 8 and 9).  This Objective willinventory and summarizethe roles ofthe existing management authorities (e.g., WDNR, Town Boards…etc.), rules and regulations andpractices that shape the management of Lake Owen.  Inventoried information will then be compared with managementneeds to assess implementation capacity.
Objective 3 –Characterize Lake Habitat($3,314) To accurately reflect in-lake habitat conditions in the comprehensive lake management plan, it is necessary to better understand the current conditionof the shoreline and nearshore ecosystems in Lake Owen.  This Objective willdescribe the current condition of shoreline and nearshore habitat and identify unique habitat features within Lake Owen.  Shoreline and nearshore habitat will be quantified usingmethods described by the Environmental Protection Agency (USEPA, 2007).  Following this method, sample transect points will be identified at 30-40 locations around the lakeshore.  At each transect, data will be collected to describe the habitat condition and level of disturbance inriparian and littoral zones of the lake using a series of semi-quantitative ranking criteria.  Data will all be geospatially processed and represented in a series of maps that describe the relative condition of the nearshore and shoreline habitat andextrapolated across parcels with

different land use types to highlight areas of critical habitat and identify sites for shoreline restoration around Lake Owen.
Objective 4 –Characterize Watershed Land Use and Nutrient Runoff($3,643) This Objective will: 1) clarify the watershed boundarythat will be used to manage thelake (i.e., the lakeshed); 2) describe the relative land use and land cover present throughout the lakeshed; and 3) estimate nutrient loading from the watershed.  All watershed assessment and characterization work will be conducted using ArcGIS and based off of the DNR land use/land cover dataand/or any higher resolution local datalayers.  Assessment of any future land use will be based on long range goals identified in local comprehensive plans, if available. Critical and sensitive habitat will be identified by summarizing existing management documents and inventorying the Natural Heritage Inventory database.  Land use and land cover data willbe ground-truthed with on-site field visits.
Phosphorus loads from watershedrunoff will be calculated for all land areasusing land-use specific phosphorus export values. Phosphorus loads will be estimated using the non-point source module in the Wisconsin Lake Modeling Suite (WiLMS).  Average, per acre nutrient loads will be estimated for each subwatershed based on current land uses and compared with average, per acre nutrient loads from the corresponding pre-development vegetative communities to identify areas for potential implementation of different Best Management Practices.  A summary of applicable BMPs will be included to guide potential implementation.   Nutrient loads from a range of different potential watershed conditions will be generated and used as input parameters the WiLMS condition response model (see Objective 7 for further detail on the WiLMS model).
Objective5–Characterize Water Quality ($8,605) To understand water quality dynamics in Lake Owen, it is necessary to understand the impact of in-lake processes, in addition to the watershed processes described above.  This Objective will supplement existing water quality data withmore detailed nutrient and dissolved oxygen profile datato develop a nutrient budget for Lake Owento support the development of an AQUATOX in-lake aquatic responsemodelfor the northern and southern sections of the lake (see Objective 7 for more detail).  Data collected for this Objective will beusedto more accurately characterize temporalwater qualityvariability, assess in lake stratification and mixing dynamicsand estimate internal phosphorus loading(See Objective 7 for more detail).  Existing data will be supplemented by collecting water quality data monthlyover a two year period and increasing samplecollection effortsto include samples from thenorthern and southern sections of Lake Owenand in the epi, meta and hypolimnion layers of the lake during stratification.  Collection of monthly water quality data fromepi, meta and hypolimnion layers is necessary for the calibration of the AQUATOX model(s) and for the development of an in-lake nutrient budget.
All water quality samples will be collected following methodsoutlined by USEPA (2007).  Surface water samples will be collected using a two-meter composite method.  Samples will be collected from the deepest point in the northern and southern sections of the lake.  Surface water samples will be analyzed for TP, SRP, Chlorphyll-a and Total Nitrogen.  Meta and hypolimnion samples will be collected using a VanDornsampler and analyzed for TP and SRP.  Both TP and SRP data in meta and hypolimnion samples are necessary to identify the source and flux of total phosphorus during the development of a nutrient budget.  Internal phosphorus loads will be estimated following methods described by Nürnberg(1987) and using the AQUATOX simulation program (see Objective 7).  Dissolved oxygen and temperature data will be collected throughout a vertical profile using a YSI multi-probe water quality meter.  All sample analysis and data processing will be conducted by the Northland Environmental Analysis Laboratory (NEALab) at Northland College following

Standard Methods for Analysis of Water and Wastewater 21st Ed. (2005).  Analysis of water quality data at the NEALab is contingent on an approved certification with the Wisconsin State Lab of Hygiene (in the absence of certification all samples will be analyzed by the State Lab).  All data will be uploaded into the SWIMS database.  These data will then be used to calibrate and validate an in-lake aquatic response model(see Objective 7), develop a nutrient budget and establishwater quality management goals for Lake Owen.
Objective 6–Characterize Biological Communities ($3,393) To develop a more comprehensive understanding of the biological communitiesin Lake Owen, it is necessary to expand the existing data to include a suite of species that represent a broader range of trophic levels and habitat types.  To this end, we will collect data to characterize aquatic macrophyte and planktoncommunities.  The presence of any threatened, rare or endangered species will be identified by working with WDNR staff to query the NHI database.  Existing and newly collected data will be used to develop management goals for fisheries and aquatic plants as part of the stakeholder process (See Objective 8).
Aquatic macrophyte communities have been widely recognized as an important component of lake management.  Lake Owenmacrophyte communities will be sampled in year one of this project using point intercept methodologies described by Hauxwell, et al. (2010).  Macrophyte data will be analyzed to characterize relative species abundance,invasive species distribution,species diversity and Floristic Quality.  Allresults will be geospatially represented to identify areas of critical habitat.
Plankton communities are important drivers of water clarity and foodweb interactions in lakes and have been identified as a key consideration when determining the timing of fisheries stocking efforts.  For this project in particular, plankton data are necessary to calibrate and validate the in-lake aquatic response model (see Objective 7 for more detail).  To this end, phytoplankton and zooplankton communities will be sampled monthly during year one of this project.  All plankton data will be collected following standard plankton tow methods outlined by the USEPA (2007).
Objective 7–Characterize Ecosystem Interactions($4,309) To understand the relative role of the different components of the Lake Owenecosystem, it is necessary to develop a framework that relatesphysical, chemical and biological processes.  To this end,we will develop an in-lake aquatic response model using the AQUATOX simulation program.
AQUATOX is a PC-based ecosystem model that predicts the fate of nutrients, sediments, and organic chemicals in water bodies, as well as their direct and indirect effects on the resident organisms. AQUATOX simulates the transfer of biomass and chemicals from one compartment of the ecosystem to another. It does this by simultaneously computing important chemical and biological processes over time. AQUATOX simulates multiple environmental stressors (including nutrients, organic loadings, sediments, toxic chemicals, and temperature) and their effects on the algal, macrophyte, invertebrate, and fish communities. AQUATOX can help identify and understand the cause and effect relationships between chemical water quality, the physical environment, and aquatic life. It can represent a variety of aquatic ecosystems, including vertically stratified lakes, reservoirs and ponds, rivers and streams, and estuaries (EPA 2009, http://www.epa.gov/waterscience/models/aquatox/).
AQUATOX was selected to model the Lake Owen ecosystem (instead of WiLMS or BATHTUB) because of the ongoing concerns related to nutrient loading in the lake, potential for foodweb control of water quality and long historical dataset and observedchanges for the fish community.

AQUATOX estimates water quality conditions by simulating the interaction of both bottom-up and top-down food-web processes.   This diagnostic ability provides a range of insights into the drivers of in-lake water quality conditions not captured in WiLMS or BATHTUB, but requires a richer data set for calibration (e.g., more frequent nutrient sampling and plantkton data).  AQUATOX also integrates the Di Torro (1990) sediment diagenesis model to estimate internal loading (particularly as it relates to hypolimnetic anoxia) and thus provides a more rigorous method for accounting for internal nutrient dynamics.  Because of these capabilities, AQUATOX is becoming increasingly utilized to estimate the effects of nutrient loading in aquatic ecosystems around the US.
For Lake Owen, two AQUATOX models will be developed to independently represent the northern and southern sections of the lake.  Lake Owen is being partitioned into two models based on the distinct longitudinal water quality gradients that have been observed over the last 20-years (see the Water Quality section above for greater detail).
Lake Management Plan Development
The existing information and newly collected data described above will be integrated to develop a detailed lake management plan that describes howthephysical, chemical, biological and social processesaffect,and are affected by, use of theLake Owen.  To maximize support for the resulting management goals and recommendations, the plan will be developed through an extensive stakeholder involvement process.
Objective 8–Engage Stakeholders in Lake Management Planning($4,077) The stakeholder involvement process will be comprised of a series of meetingsand surveys.  The goals of this Objective are to 1) increase understanding how the lake is perceived, valued and used by different stakeholder groups, 2) communicate how the physical, chemical and biological processes within the lake affect, and are affected by, lake use, 3) develop a series of management goals for the lake that represent the broad range of stakeholder values.
Kick-off Meeting: A kick-offmeeting will be held near the start of the project and designed to inform stakeholders about the project and its goals. Thismeeting will provide both an opportunity for early input but also provide an educational forum on lake ecology.  This will likely be held in conjunction with the annual meeting for the NLA. Stakeholder Survey: Details of the stakeholder survey are described in the Lake Uses and Users section above. Steering CommitteeMeetings: A Steering Committee will be established of residents, citizens and natural resource professionalsto review data,establish goalsand objectives and identify preferred management options throughout thedevelopment of the comprehensivemanagement plan.  This committee will likely meet 2-4 timesper year.  Review and Comment:  Following completion of the draft lake management plan, copies will be distributed for comment,reviewand DNR approval. Wrap up meeting: At the conclusion of the project,findings and recommendation will be presented and the selected management alternatives explained. Public Information Forums: Throughout the development of the plan,stakeholderswill be updated through existing communication media (e.g., the LOAand Town ofNamekagon Newsletters).  In particular, public information forums will be used to communicate issues related to the potential for invasive species introduction and restorationof shoreline habitat.
Objective 9–Develop a Comprehensive Management PlanforLake Owen($3,958)

Comprehensive Management Planning for Lake Owen
2012
All data collected throughout this project will be combined with existing data sources to develop a comprehensive management plan.  This Objective will1) relatethe identifiedmanagement goals to the current lake conditions and stressorsand 2) develop a series of recommendationsto sustain and/or restore identified lake uses. 
SummarizeLake Uses and Stakeholder Values: Results from the stakeholder survey will be summarizedand integrated with existing survey dataand the complete survey will be included as an Appendix. Management Goals: Management goals from the stakeholder process will be summarized. Lake Condition Assessment: Current lake conditionswill be described using a relative shoreline habitat quality index, growing season water quality values (e.g., trophic status index) and biological community data.  Stressor Analysis: Current lake stressors will be described by summarizing the presence of invasive species, and through a quantitative summary of land use/land cover and shoreline development. Management Recommendations: The final planwill highlight the relationship between the different stressors described above and current lake conditions.  Recommendations will then describe the most efficient and effective sequence of management initiatives that will facilitate alignment of lake conditions withthedesired management goals.  Recommendation will also highlight any future threats to lake condition identified through the data analysis (particularly as it relates to future land use conditions). Monitoring Needs and Recommendations: Based on the existing data and resulting management goals, a monitoring framework will be developed to track management progress for Lake Owen. Non-technical Summary:  Results from the plan will be summarized in a short (~3-page) non-technical summary that will be distributed to all lakeshore owners.
