Upper Fox Basin TMDL Monitoring NER06_10

Purpose

**2nd year of monitoring for the Upper Fox Basin TMDL** NER biologists and CO SWAT will collect water samples from the Fox River, Puchyan River, Fon du Lac River, Montello River, Waukau Creek, Lake Poygan, Lake Winneconne, Lake Butte des Morts, and Lake Winnebago to be analyzed for TSS, Total Phosphorus, and Dissolved Phosphorus that will be used in modeling the sediment and phosphorus loads to Lake Winnebago. Results of the modeling will be used in developing a TMDL for Lake WInnebago to drive management practices in the Upper Fox Basin.

Objective

The development of a TMDL to address the phosphorus and sediment loading to Lake Winnebago is necessary because 50% of the nutrient and sediment load to the Lower Fox River is directly from Lake Winnebago. In order for the Lower Fox TMDL (currently in development) to meet its goals, reducing the pollutant load from Lake Winnebago is critical. The Objective of this project is to address phosphorus and sediment loading from the Upper Fox River Basin to Lake Winnebago, and therefore support the work of the Lower Fox River Basin TMDL. This will be the 2nd of 3 years of data needed to accuratley model the sediment and phosphorus laoding to Lake Winnebago

Outcome

WTTM There are 11 sample sites total between the 9 waterbodies that will be sampled at varying sampling schedules: On the Fond du Lac, Montello, and Waukau, bi-weekly samples will be collected from March to November, and monthly from December to February. On the Fox and Puchyan, weekly samples will be collected from March 1 to June30, and bi-weekly July 1 to February 28. On lakes Poygan, Butte des Morts, and Winneconne, samples will be collected at 1 sites on each lake bi-weekly from May 1 to Sept. 30, and 1 time beneath the ice in February. Lake Winnebago will have 3 sites sampled on it during the same sampling schedule as the other lakes. Event samples will be collected by automated samplers installed on the Montello river, and Fond du Lac River. This project estimates that 20 event samples will be collected this year at each site.
