Fish and Aquatic Life
, in the Crossman Creek and Little Baraboo River Watershed, is a 24.78 acre lake that falls in Sauk County. This lake is managed for fishing and swimming and is currently not considered impaired.

An impoundment formed by an old mill dam on the Baraboo River at LaValle. The watershed of the pond totals 235 acres of which 60 percent is used for agricultural practices. Heavy bank erosion and early spring flooding are major problems in the watershed, therefore causing heavy siltation in the pond. Carp and aquatic vegetation are also severe use problems, but a limited fishery of northern pike, smallmouth bass, and panfish does exist. Shrub swamp wetland totaling 96 acres adjoins the northwestern end of the pond. Muskrats and puddle ducks are common. Public access is available from one bridge crossing and the Baraboo River. Five dwellings adjoin the pond in LaValle.
Author Surface Water Inventory Of Wisconsin
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.
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 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.

La Valle Mill Pond is located in the Crossman Creek and Little Baraboo River watershed which is 213.80 mi². Land use in the watershed is primarily forest (36.40%), grassland (32.90%) and a mix of agricultural (20.40%) and other uses (10.30%). This watershed has 466.61 stream miles, 244.11 lake acres and 6,321.59 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Available for runoff impacts on streams, Not Available for runoff impacts on lakes and High for runoff impacts on groundwater and therefore has an overall rank of High. This value can be used in ranking the watershed or individual waterbodies for grant funding under state and county programs.However, all waters are affected by diffuse pollutant sources regardless of initial water quality. Applications for specific runoff projects under state or county grant programs may be pursued. For more information, go to surface water program grants.
