The water going by affects and is affected by the land.
St. Croix National Scenic Riverway is one of the many parks that proposed projects for 2008, to be included in the Centennial Challenge . Attached you will find the
Centennial Strategy for 2008. One of the projects submitted has been included among the 201 Certified Eligible Centennial Challenge Proposals.
Protect Water Quality of the St. Croix National Scenic Riverway. This project is to produce a computer model to predict nutrient and sediment loading in the St. Croix River Basin and train water resource professionals throughout the basin in how to apply the model at local, county and subwatershed levels. This work is needed to realize the goal of reducing phosphorous and nutrient loading in the St. Croix National Scenic Riverway by 20 percent by 2020. This goal is science-based and was established through extensive research of the interagency St. Croix Basin Water Resources Team (NPS, USGS, MN Pollution Control Agency, MN DNR, WI DNR, Twin Cities Metropolitan Council, Science Museum of Minnesota Watershed Research Station, and other partners).
It is widely assumed that the water quality of the St. Croix is pristine, because of its status as a Wild and Scenic River and because river users have historically enjoyed high-quality water. However, recent studies carried out by the National Park Service and Basin Team partners document that water quality is threatened by increasing nutrients and sedimentation. Three tributaries (the Apple, Willow and Kinnickinnic) are the largest contributors of suspended sediments and nutrients during base flow and storm runoff events. Scientists at the St. Croix Watershed Research Station have developed a Soil and Water Assessment Tool (SWAT), a computer model that predicts nutrient and sediment loading. It has been piloted and fine-tuned in the Willow River of Wisconsin and is ready to be applied on the basin scale.
The Wisconsin Department of Natural Resources will be partnering with the Riverway in funding this project. Information on additional matching funds from other partners is likely, with the expectation that the project could be extended beyond 2008.
