Fish and Aquatic Life
Lemonweir River - The Lemonweir River in the Lower Lemonweir River Watershed - LW27)
extends from its confluence with the Wisconsin River
upstream to the dam at New Lisbon. The river has a diverse warm water sport fishery. The
dominant gamefish in this reach is the smallmouth bass. Streambank erosion is a problem in
this reach, resulting in sand and sediment accumulating in the deeper holes and backwater
areas, and increased turbidity. It is believed that the proposed removal of the Lemonweir Mill
Dam would eliminate backwater spawning and nursery areas.
Lemonweir River in the Little Lemonweir River Watershed (LW29) - The Lemonweir River flows
through eastern Monroe County and west central Juneau County
in a southeasterly direction for 56 miles before reaching the Wisconsin River between Castle
Rock Lake and the Wisconsin Dells. The Lemonweir River in this watershed extends from the
dam in New Lisbon upstream to where the South and East Forks of the Lemonweir River
converge at Wyeville. These upper 25 miles of the Lemonweir River support a warm water
sport fishery comprised of northern pike, walleye and panfish. The river is bordered by
hundreds of wetland acres and agricultural lands. From Wyeville downstream past the
confluence of Bear Creek, the Lemonweir River has been straightened. However, a low
gradient of only three feet per mile in Juneau County creates a meandering river down to New
Lisbon which can be difficult to navigate. Since the last biological survey was conducted in
1966, a fish and habitat survey should be conducted on the Lemonweir River upstream of
New Lisbon to document existing conditions. Access to the Lemonweir River upstream of
New Lisbon is from seven road crossings. The WDNR has been purchasing easements along
sections of the river to establish riparian buffers to improve stream health.

The Lenaonweir River in this watershed extends from its confluence with the Wisconsin
Rives upstream to dam at New Lisbon. The river has a diverse warm water sport fishery.
The dominant gamefish in this reach is the smallrrlouth bass (WDNR, 1991).
Streambank erosion is a problem in this reach, resulting in sand and sediment
accumulating in the deeper holes and backwater areas, and increased turbidity
(Ironside, 1991). It is believed that the proposed removal of the Lemonweir Mills dam
would eliminate backwater spawning and nursery areas (WDNR, 1991).
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.
Juneau County proposes to amend or create a shoreland zoning ordinance that complies with the requirements of NR 115, Wisconsin Administrative Code (as revised effective February 1, 2010) and retain existing regulations that exceed the water resource protections of NR 115 or are specific or unique to local needs.
Biomonitoring Toxicity Tests
WRM should conduct monitoring for the presence of toxic substances in
fish in New Lisbon Lake (Type B).
Dam Safety or Removal
Examine the impact of removing the Lemonweir Dam to determine if the removal would eliminate necessary spawning and nursery areas.
Monitor Fish Community
The Lemonweir River should be assessed to determine if rare aquatic elements previously found are still present.
Monitor Targeted Area
The populations of leopard frogs in the watershed should be surveyed to determine the health and abundance of the frog. If a decline is indicated, more work should be done to determine the potential causes.
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.

Lemonweir River is located in the Lower Lemonweir River watershed which is 209.62 mi². Land use in the watershed is primarily forest (36.20%), agricultural (31%) and a mix of wetland (22.30%) and other uses (10.60%). This watershed has 384.35 stream miles, 558.61 lake acres and 17,722.41 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, Low 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.
