Presentation: Carstens Lake Water Quality Improvement Project

Proposed Sedimentation and Treatment Basin with Sorption Technology

Lakeshore Natural Resource Partnership (LNRP) and partners at Stantec and the UW–Stevens Point are working on a design for water quality treatment along Pine Creek, a direct tributary to Carstens Lake. The project was initiated as a result of a 3-year study by MCLA (2012-2014), which identified high levels of phosphorus (>40 ppb) in Carstens Lake. The subsequent 2018 Carstens Lake Comprehensive Management Plan recommends offline structures adjacent to Pine Creek for water quality treatment to mitigate phosphorus loading in Carstens Lake, and was the catalyst for this project.

Partners are proposing to construct an offline sedimentation basin, which will attenuate high stream flows and allow particulate solids and nutrients to settle in the basin. Secondary treatment will be provided by implementing sorption technology in the outlet berm that will capture reactive phosphorus prior to discharge back into Pine Creek and eventually Carstens Lake. The sorption technology, developed by Professor Kyle Herrman at UWSP, uses steel furnace slag to remove dissolved phosphorus from the water stream.

UW-SP and Wisconsin Department of Natural Resources environmental toxicologists are in the process of reviewing the slag material for field application. UW-SP is waiting on conditional approval from WDNR. Pending WDNR approval and additional grant funding, construction is anticipated to move forward in late 2022 or early 2023, and sorption technology will be installed in Spring 2023.

Jim Kettler, Director of Projects, Lakeshore Natural Resource Partnership

As an ecologist with special interests in restoration ecology, agroecology, and ecosystem management, Jim received a PhD in ecology from the University of Georgia and a BS in Wildlife Ecology from the University of Wisconsin-Madison. From 1985-1995, he worked at the interface of land management issues examining potential improvements of traditional agricultural systems and restoration of degraded pastures in Costa Rica, working with traditional farmers on inland fisheries development in West Africa, serving as an ecologist for the Nooksack Indian Tribe in western Washington State, and conducting training workshops on sustainable agriculture for agricultural extension agents in the state of Georgia.

James also taught at the Graduate School of Environmental Studies at Bard College. From 1996-2006, he was involved with the International Honors Program, as Traveling Faculty, as Academic Director, and Executive Director. Jim and his family live in an environmentally designed home using geothermal, passive solar, and a wood stove in the Town of Centerville in southern Manitowoc County.

 

 

Sarah Majerus, Environmental Scientist, Stantec

Sarah is a wetland ecologist and enjoys working with local non-profits, businesses, and municipalities to provide integrated solutions that protect and conserve water resources. Her goal is to educate clients and help them design projects that minimize impacts to natural resources and provide ecological function for the future.

With project experience including wetland determination and delineation, botanical surveys, and habitat restoration planning and design, Sarah also has expertise in naturalized stormwater management, watershed planning, native landscape planning, and site planning for recreational development. She is a professional wetland scientist (PWS) with the Society of Wetland Scientists and a Wisconsin Department of Natural Resources (WDNR) Assured Wetland Delineator.

Outside of work, Sarah enjoys exploring and traveling with her family—she’s typically in search of opportunities to recreate in, on, or near water.
