PACRS is about working together to make a positive change. In order for positive change to take place it is very necessary that trust and partnership be the cornerstone of any discussions. It’s important that working together becomes the way, not the exception. These two attributes, trust and partnership played a significant role in the accomplishments and projects listed on this page.

Draw Down

In the winter of 2009, WRPCO (Wisconsin River Power Company), WDNR (Wisconsin Department of Natural Resources) and PACRS (Petenwell And Castle Rock Stewards), worked collaboratively to delay the winter draw down on Lake Petenwell in an attempt to have aquatic plants re-establish themselves.

Restoring the aquatic plant community in the littoral (between the high and low water levels) zone would improve fish and wildlife habitat as well as attenuate nutrients that otherwise could create serious algal blooms on the reservoir every year. A mutual agreement to postpone the draw down to after February 10 was reached. The winter of 2010 was the first year of the delayed draw down and then again in 2011 and 2012.

WRPCO will again implement the delayed drawn down on or about February 10, 2014, as long as safety is not an issue. After the vegetation survey is taken, we will have completed a 5 year study to determine if the delayed draw down is effective at stimulating aquatic plant growth.

PCO, planted aquatics in the upper reaches of Lake Petenwell in the summer of 2012 and 2013. These sites are not included in the plant surveys regarding the draw down.
We appreciate the cooperation and efforts WRPCO and WDNR have provided on this study.

Total Maximum Daily Load (TMDL)

The Wisconsin Department of Natural Resources (WDNR), together with many public and private partners throughout the basin, are working to improve water quality of the Wisconsin River, its reservoirs, and tributaries. The water quality improvement study will be undertaken in the form of a Total Maximum Daily Load (TMDL). The TMDL study and implementation plan will provide a strategic framework and prioritize resources for water quality improvement in the Wisconsin River Basin. The Wisconsin River TMDL study area spans Wisconsin’s central corridor from the river’s headwaters in Vilas County to Lake Wisconsin in Columbia County, covering 9,156 square miles – approximately 15 percent of the state. Under existing conditions, many reservoirs and tributaries in the Wisconsin River do not meet water quality standards due to excess pollutant loads, meaning they are not suitable for their designated uses, such as fishing, wildlife habitat, and/or recreational activities such as boating and swimming. The Wisconsin River Basin total maximum daily load (TMDL) will determine the total amount of phosphorus and suspended solids that can be discharged into the river, its tributaries and reservoirs, and still meet water quality standards and develop a plan for achieving the needed reductions.

The study, which is slated for completion in 2017, was the result of local residents and business engaging their legislators by providing pontoon rides on Petenwell and Castle Rock Reservoirs in 2008. After these elected officials observed the water quality problems firsthand, the state legislature allocated funding for a water quality improvement project, and directed the WDNR to develop a TMDL. The TMDL incorporates various components including water quality monitoring, modeling, and an allocation process which will require proportional reductions in phosphorus upstream to achieve phosphorus goals in Petenwell and Castle Rock.
