The bipartisan National Fish Habitat Conservation Through Partnerships Act, which would greatly benefit the MGLP, was recently introduced in the House and Senate. The MGLP asks you to consider supporting these bills through your organization if possible, writing your representatives personally, and sharing information on the bills to those that may be interested.

The Midwest Glacial Lakes Partnership awarded the Eagle Lake Paw Paw Association (ELPPA) a grant in 2017 to test whether naturalized shorelines and deep-rooted shoreline vegetation can mitigate septic system contaminant and bacterial discharges to lakes. Over the past year, Kieser & Associates (K&A) has been working with the ELPPA to test seven ‘front yards’ around the lakeshore to determine how small patches of native plants grown between septic system drain fields and the water’s edge may protect water quality.

K&A is monitoring shallow groundwater at three of these sites to determine how deep-rooted plants may help prevent nutrients and bacteria from reaching the lake. They are also monitoring how these small, but potentially important, plantings may help improve fish and aquatic habitat along the lakeshore.

Test sites have been established to test groundwater both with and without native plantings. Differences in nutrient and bacteria concentrations will be used to determine whether there are real benefits with this innovative approach compared to much higher cost solutions of septic system replacement or sewering. This effort will help determine whether a simple patch of native landscaping along a residential shoreline can become an inexpensive way of mitigating this national problem of older systems contributing to water quality problems, impairing aquatic habitat and diminishing property values.

Six groundwater monitoring wells were installed at each of the three groundwater monitoring test sites in April of 2018. These were placed upgradient, downgradient and cross-gradient of septic drain fields. Two rounds of semi-annual groundwater sampling have already been conducted. Samples were submitted for analysis of soluble reactive phosphorus, nitrate nitrogen, ammonia nitrogen, total dissolved solids, chloride, and E. coli bacteria.

Nearshore macroinvertebrate sampling was conducted in May 2018 to serve as baseline conditions prior to natural shoreline installations. Samples were collected in front of each of the seven project sites, three of these also serving as groundwater monitoring sites. In July of 2018, a variety of deep-rooted native plants, co-selected with residents, were planted at four project sites, one of these with groundwater monitoring wells.

The project is scheduled to be completed in 2019 although the ELPPA may continue to support longer-term monitoring to maximize benefits of the current efforts. These data will help determine whether this technique is viable, cost-effective, and scalable approach to address septic system discharges to lakes and streams. The MGLP will share the results of this project through future newsletters.

Way back in 2009, the MGLP identified the need to conduct an assessment of all ~40,000 lakes in its footprint to inform fish habitat conservation. Partners recognized the need to tailor their actions to each lake and to prioritize their actions given the limited amounts of funding and resources. Almost ten years later, following multiple iterations, countless meetings, and feedback from partners, the MGLP is finalizing the assessment and building a web viewer for partners to use it in their work.

The assessment is a product of the MGLP’s Science and Data Team, who contributed their own time to bring it together. The assessment predicts the presence or absence of four species of fishes representing temperature guilds, and uses climate change and land use change information to assess threats in the shoreland surrounding the lake and in the watershed. The team took great care to ensure that these efforts were beneficial to fisheries managers, conservation organizations, and other practitioners. After repeated rounds of feedback from the MGLP Steering Committee, the team conducted a survey this March of almost 400 MGLP partners to learn about their information needs and uses for the assessment. The team developed a draft web viewer based on that feedback, and in June the team conducted a 2-day workshop in Minnesota to gather even more input on questions such as “Could you use this tool with little training or GIS experience?” and “What information could you use from such a tool to assist your fish habitat conservation efforts?” Feedback from the workshop is helping the team to tailor information to meet practitioners’ needs.

For example, the assessment and web viewer will help practitioners identify specific sets of conservation actions based on the unique set of threats facing each lake. Whether their backgrounds were in outreach and education, land acquisition, fisheries management, or habitat grant administration, participants were excited to start using the assessment and web viewer. This was summed up in one of the anonymous feedback forms by a participant who wrote, “I look forward to seeing the next version of the tool, and ultimately using it for project prioritization, education and outreach, etc.”

The Science and Data Team is now implementing recommendations from the workshop to improve the web viewer, which it plans to release in the coming months. Stay tuned!

One of the Midwest Glacial Lakes Partnership’s primary objectives is to share science and management to improve and protect inland lake fish habitat across the region. Too often, boundaries between organizations become boundaries to information flow, and these boundaries hinder the ability of scientists, managers, and practitioners to accomplish their goals. An advantage of the Partnership is the opportunity to share experiences across organizations and learn from others. Through these conversations it became clear that there was a need for sharing recommendations for managing inland lake fish habitat. To address this issue, the Partnership organized a symposium at the 78^th Midwest Fish and Wildlife Conference in Milwaukee, WI.

The “Managing fish habitat and fisheries affected by habitat in inland glacial lakes” symposium hosted ten speakers, each of which presented a review of current research and management on an important information gap below.

• Joe Nohner and coauthors discussed the benefits of using landscape ecological approaches to prioritize and inform lake management, using the Midwest Glacial Lakes Partnerships’ upcoming Phase II Assessment of Inland Lake Fish Habitats as an example of how such an approach could be implemented.
• Catherine Hein reviewed literature and field-experiences on efforts to prevent and/or reverse eutrophication, offering case studies to illustrate successful methods and avoid common pitfalls.
• Ralph Tingley and coauthors presented a framework for climate change adaptation in Midwest glacial lakes and highlighted strategies that have been implemented throughout the region.
• Nick Phelps identified the importance of understanding the environmental factors that contribute to fish kills and created models to predict future fish kills based on water temperature, primary productivity, human disturbance, and other factors.
• Jim Breck and coauthors presented models of bluegill growth based on landscape-scale drivers of fish habitat.
• Josh Raabe and coauthors reviewed the Walleye literature on how inland lake habitat may influence successful natural reproduction and stocking efforts and highlight remaining critical research questions.
• Greg Sass and coauthors presented research results from a series of coarse woody habitat additions and removals to inland lake littoral zones, highlighting issues related to production vs. attraction of fishes, the benefits of coarse woody habitat to different species, whether the effects of coarse woody habitat differ from fish cribs, and whether angler behavior and success are influenced by these habitats.
• Paul Radomski discussed techniques for aquatic plant inventory and monitoring, management options for aquatic plant protection, non-indigenous species control, and potential research opportunities to better understand aquatic plant and fish relationships.
• Jonathan Hansen provided a synopsis of aquatic plant management permitting in Minnesota, a program that balances the desires of lakeshore property owners and the need to conserve habitat for aquatic animals.
• Patrick Goggin and Pamela Toshner provided an overview of the Healthy Lakes Initiative in Wisconsin, whereby lakefront property owners are provided technical and financial assistance to implement specific best management practices to improve lake health.

The Midwest Glacial Lakes Partnership and authors associated with this symposium are currently pursuing publication options to share the information from this symposium broadly with project partners.

The National Fish Habitat Partnership has unveiled its annual list of “Waters to Watch”, a collection of rivers, streams, estuaries, lakes and watershed systems that will benefit from strategic conservation efforts to protect, restore or enhance their current condition. These voluntary, locally-driven projects represent some of the top conservation activities in progress implemented throughout the country by 20 regional Fish Habitat Partnerships, including the Midwest Glacial Lakes Partnership.

The Midwest Glacial Lakes Partnership is funding the replacement of an undersized and perched culvert at the outlet from Crane Lake with one that is more appropriately-sized, creating connectivity with waterbodies downstream. Minnesota DNR Fisheries Biologist Howard Fullhart explains that, “The undersized culvert creates high water velocities that fish can’t swim through, and when water flows are low, the culvert is perched and so fish aren’t able to pass. The new culvert will allow fish passage for walleye, northern pike, white suckers, darters, shiners, and other important fishes.” Crane Lake currently has lower populations than downstream lakes of migratory fish species such as walleye, white sucker, and weed shiner, a species of greatest conservation need in Minnesota’s State Wildlife Action Plan. The project is expected to increase fish community diversity and resiliency in Crane Lake by allowing fish to migrate into the lake.  “This is a really neat project,” says Fullhart, “in that it was started by the local citizens who were concerned about fish passage and the road potentially washing out. County engineers, the Minnesota DNR, and the Midwest Glacial Lakes Partnership are all providing funding and resources to the project to benefit natural resources, transportation, and surrounding property owners.”

Conservation projects, such as the Crane Lake culvert replacement, benefit the Waters to Watch by conserving freshwater, estuarine and marine habitats essential to the many fish and wildlife species that call these areas home.  These examples of conservation have been fundamental to the overall success of the National Fish Habitat Partnership since 2006.

Over time, these conservation efforts are reversing persistent declines in our nation’s aquatic habitats. Having featured over 100 partnership projects since 2007, these “Waters to Watch” are proving that science-based on-the-ground conservation efforts are truly making a difference in improving fish habitat across the United States.

“We are pleased to continue our Waters to Watch Campaign for the 11^th year in 2017,” said Tom Champeau, Chair of the National Fish Habitat Board. “The “Waters to Watch” campaign is one of our best ways nationally to highlight the work of our 20 partnerships annually.”

You may have heard that the Midwest Glacial Lakes Partnership funds habitat conservation through its grant, but did you know the Partnership catalyzes habitat conservation in other ways? With assistance from the Partnership, Clear Lake Township Land Conservancy in Indiana was recently granted an award from the FishAmerica Foundation supported in part by the Brunswick Public Foundation to complete its fish habitat conservation project .

Residents, anglers, and lake recreationists on Clear Lake were concerned about the water quality of their aptly named lake. Erosion on a popular boating destination, Kasota Island Nature Preserve, was causing excess sediments and nutrients to enter the lake, which threatened to decrease water clarity and water quality. The Conservancy applied for the grants through the Midwest Glacial Lakes Partnership and Indiana Department of Natural Resources, but was looking for additional sources of funding. The Partnership shared the FishAmerica Foundation grant opportunity with the Conservancy, and wrote a letter of support on behalf of the project. As a result, the Conservancy acquired all of the funds it will need to install a bioengineered shoreline and complete its project!

“Collaboration on large scale projects is key for organizations as small as ours,” says Bridget Harrison, Executive Director for Clear Lake Township Land Conservancy. “We appreciate all of the partners helping to make this project possible and working with the Midwest Glacial Lakes Partnership has been wonderful. We appreciate their letter of support and endorsement of our project. The shoreline restoration project along Kasota Island Nature Preserve will not only improve water quality but it will ensure that the island is here for future generations by minimizing the current loss of 4 inches of shoreline per year. ”

The Midwest Glacial Lakes Partnership is happy to support projects that align with its mission to protect, rehabilitate, and enhance sustainable fish habitats in glacial lakes of the Midwest for the use and enjoyment of current and future generations. The partnership has written letters of support for research projects and on-the-ground habitat projects.
