LAKE NOQUEBAY REHABILITATION DISTRICT: Lake Noquebay Nutrient Study - Phase 1

Purpose

Marinette County is sponsoring a project to investigate nutrient loading to Lake Noquebay, identify major nutrient sources, and evaluate the effect of various nutrient reductions scenarios on water quality, in the time span of Feb. 2018 \2013 Dec. 2020. The project elements and deliverables are specified in Marinette County\2019s Grant application dated December 8, 2017. In lake water quality conditions will be investigated along with an evaluation of ground water and watershed nutrient loading. The first goal is to evaluate current water quality conditions in Lake Noquebay by conducting water quality monitoring during the 2018 field season to characterize current water quality conditions and measure physical properties of the water column. The data will be analyzed according to the DNR protocols under WisCALM and CLMN guidance. The second goal is to evaluate the external nutrient loading to Lake Noquebay. This will be performed by: A) Conducting continuous flow monitoring on Smith Creek, Middle Inlet, Upper Inlet and the Outlet for use in watershed nutrient loading estimates and lake nutrient budgeting. B) Monitoring nutrient concentrations in Smith Creek, Midddle Inlet, Upper Inlet, and ungauged tributaries for use in watershed loading estimates, water quality modeling, and evaluation of land use effects on nutrient loading. C) Identifying zones of groundwater inflow and outflow and quantify groundwater loading D) Monitoring nutrient concentrations in groundwater for use in groundwater loading estimates and lake nutrient budgeting. Goal three consists of modeling external loading, creating a nutrient budget for Lake Noqeuebay and evaluating alternative load reduction strategies to protect the lake for future generations. Special Conditions: 1) CLMN efforts should not be duplicated and these data shall be included in the trends analysis and final reporting; 2) All CLMN shall be entered into the SWIMS database.
