Lake Mallalieu TMDL
Status of Lake Lake Mallalieu TMDL 2018 Summary of Information
TMDL Implementation Plan
Condition Assessment Report
The purpose of this work is to monitor the fall population length frequency and catch per unit effort of sunfishes, yellow perch and crappies in parts of Navigation Pool 7 of the upper Mississippi River. A secondary purpose is to estimate length and size distributions of other game fishes caught incidentally.cc
During 2008, the WDNR worked cooperatively with the St. Croix Watershed Research Station to develop a TMDL planning initiative in the Willow River Watershed. This plan is near completion. In order to achieve a 20% reduction of phosphorus to the St. Croix River, phosphorus reduction in the uplands is needed to meet the goal reduction.
ATTAINS Follow-up monitoring conducted
Monitoring work for Lake Mallileu - TMDL in development with TP,TSS, he lake is designated as high priority for eutrophication and ph impairments due to excess phosphorus, while the upstream reach of the river is a low priority for dissolved oxygen impairments. The river’s designation is due to excess phosphorus and biological oxygen demand (BOD).
