Fish and Aquatic Life
Overview
Upper St. Croix Lake, in the Upper St. Croix and Eau Claire Rivers Watershed, is a 828.27 acre lake that falls in Douglas County. This lake is an outstanding/exceptional resource water under NR102 under the Fisheries Program. This lake is managed for fishing and swimming and is currently not considered impaired.

Historical Description
This lake is situated at the headwaters of the St. Croix River. In addition to its status as a
major contemporary recreational resource this waterbody occupies a place in history as a part of
the Brule - St. Croix portage. The early European explorers often stopped on this lake in their
journeys from Lake Superior to the Mississippi River.
Upper St. Croix Lake has been nominated as an "Outstanding Resource Water" and has an
excellent fishery as well as providing significant aquatic recreational opportunities. This lake
does exhibit some symptoms of eutrophication that are somewhat unexpected from a waterbody
located at the headwaters of a stream system. The Village of Solon Springs is situated on the
west shore of this lake and did experience some problems with groundwater pollution from
individual sewage disposal systems in the past. This problem has been corrected with the
installation of a municipal collection and treatment system.
A feasibility study to assess the current status of water quality in this lake and the nutrient
budget would be a desireable first step for this lake community. A long range lake management
plan would be the logical goal for this important lake.
This ORW nominated lake should be considered as a high priority for a Priority Lakes project.

General Condition
Upper St. Croix Lake (2747300) was assessed during the 2016 listing cycle; total phosphorus sample data were clearly below 2016 WisCALM listing thresholds for Recreation use and Fish and Aquatic Life use. Chlorophyll sample data were clearly below FAL use listing thresholds and did not exceed REC listing thresholds. This water was also assessed for chlorides and sample data were clearly below 2016 WisCALM chronic and acute listing criteria for the Fish and Aquatic Life use. This water is meeting these designated uses and is not considered impaired.

Condition
Wisconsin has over 84,000 miles of streams, 15,000 lakes and milllions of acres of wetlands. Assessing the condition of this vast amount of water is challenging. The state's water monitoring program uses a media-based, cross-program approach to analyze water condition. An updated monitoring strategy (2015-2020) is now available. Compliance with Clean Water Act fishable, swimmable standards are located in the Executive Summary of Water Condition in 2018. See also the 'monitoring and projects' tab.

Nine Key Element Plan
Upper St. Croix - Eau Clair Rivers PWS Plan - Nine Key Element Plan - The Upper St. Croix - Eau Clair Rivers Priority Watershed is at the headwaters of the St. Croix River and the Mississippi River system. The historical significance of this resource is well documented in many accounts referring to the beauty and abundance of this outstanding resource. In 1988, the St. Croix River was designated as an Outstanding Resource Water by the State of Wisconsin. The Upper St. Croix - Eau Clair Rivers watershed project has a protection orientation, as opposed to the more traditional remediation based watershed projects, and takes a proactive approach to prevent nonpoint pollution before it happens.
Management Goals
Wisconsin's Water Quality Standards provide qualitative and quantitative goals for waters that are protective of Fishable, Swimmable conditions [Learn more]. Waters that do not meet water quality standards are considered impaired and restoration actions are planned and carried out until the water is once again fishable and swimmable
Management goals can include creation or implementation of a Total Maximum Daily Load analysis, a Nine Key Element Plan, or other restoration work, education and outreach and more. If specific recommendations exist for this water, they will be displayed below online.
Monitoring
Monitoring the condition of a river, stream, or lake includes gathering physical, chemical, biological, and habitat data. Comprehensive studies often gather all these parameters in great detail, while lighter assessment events will involve sampling physical, chemical and biological data such as macroinvertebrates. Aquatic macroinvertebrates and fish communities integrate watershed or catchment condition, providing great insight into overall ecosystem health. Chemical and habitat parameters tell researchers more about human induced problems including contaminated runoff, point source dischargers, or habitat issues that foster or limit the potential of aquatic communities to thrive in a given area. Wisconsin's Water Monitoring Strategy was recenty updated.
