Big Eau Pleine TMDL

Purpose

Big Eau Pleine Reservoir is a 6348 acre lake located in Marathon County. It has a maximum depth of 46 feet. Visitors have access to the lake from public boat landings. Fish include Musky, Smallmouth Bass, Northern Pike and Walleye. The lake's water clarity is low.

The Big Eau Pleine Flowage (wbic 1427200) is listed on the Federal 303 (d) list for violations of the state dissolved oxygen and pH water quality standards. The Big Eau Pleine River is also on the list for dissolved oxygen levels below the water quality standard. Both listings are a result of excessive nutrient loading, primarily phosphorus, to the river and flowage.

The Department started a multi-year water quality study in 2009 to develop a TMDL for the river and flowage. The study was completed in conjunction with Wisconsin Valley Improvement Company's (WVIC) three year flowage monitoring plan mandated in their FERC license. WVIC will began flowage monitoring in 2010 and continued through 2012. The Big Eau Pleine River at STH 97 has been sampled monthly for nutrients and solids since 2005 as part of baseline Tier I wadeable stream monitoring and special project 303d monitoring.

TMDL monitoring started in October 2009 with bi-weekly tributary sampling completed by the Department and an advanced volunteer monitor. TMDL monitoring continued through September 2012 and included 2013. Monitoring has been conducted by DNR and partners throughout the these initial data gathering years.
