Description

The USGS is offering a funding opportunity to a CESU partner for research in the Green Bay, Wisconsin area. Apple Creek (drainage area of 54 sq mi) is part of the Total Maximum Daily Load (TMDL) and watershed management plan for total phosphorus (TP) and total suspended solids (TSS) in the Lower Fox River Basin. Apple Creek has 24 miles of stream length on the Wisconsin state impaired waters list for TP and TSS. Recent stream inventories of neighboring Plum Creek by Outagamie County indicate that 24 of the 43 miles inventoried had actively eroding banks. Preliminary estimates are that these banks could be contributing 45 percent of the TSS annual loading measured at the USGS gage. If stream processes are similar in Apple Creek and producing almost half of the annual loading of TSS, the proposed TMDL goal to reduce TSS by 70 percent will not be achievable through upland soil conservation practices alone. Products from this study will include GIS maps and spreadsheets of stream corridor sources and sinks of sediment and TP.
