Pensaukee River, in the Pensaukee River Watershed, is a 49.40 mile river that falls in Oconto and Shawano Counties. This river is managed for fishing and swimming and is currently not considered impaired.

Flows in the river are extremely variable. Flows near Pensaukee have ranged from 5.3 to
3,880 cubic feet per second. At Krakow the Pensaukee River's lowest seven-day average
low flow in 10 years (Q7.10) was zero.
The Army Corps of Engineers maintains a federal navigation channel at the mouth of the
Pensaukee River. Several commercial fishing boats use the harbor. The authorized
navigation project extends 3,700 feet from Green Bay upstream. The harbor and
navigation channel were last dredged in 1965. The Corps assessed Pensaukee River
sedimen iuality in 1982 and found grease, oil and cadmium present. In 1985, DNR
Water Resources Management (WRM) analyzed sediment samples from the mouth of the
river for PCBs. Ley 1s were less than 0.05 micrograms per gram (uglg), which indicates
that PCBs are not a concern.
WRM and Fisheries Management personnel believe the Pensaukee River is significantly
affected by nonpoint source water pollution.

Pensaukee River (412900) was placed on the impaired waters list for total phosphorus in 2014. The 2016 assessments showed continued impairment by phosphorus; total phosphorus sample data exceed 2016 WisCALM listing criteria for the Fish and Aquatic Life use, however, available biological data do not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category). Based on the most updated information, no change in existing impaired waters listing is needed.

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
Pensaukee River PWS Plan - Nine Key Element Plan - The Pensaukee River Priority Watershed Project plan assesses the nonpoint sources of pollution in the Pensaukee River Watershed and guides the implementation of nonpoint source control measures. These control measures are needed to meet specific water resource objectives for the Pensaukee River and its tributaries. The purpose of this project is to reduce the amount of pollutants originating from nonpoint sources that reach surface water and groundwater within the Pensaukee River Watershed.

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.

Pensaukee River is located in the Pensaukee River watershed which is 163.77 mi². Land use in the watershed is primarily agricultural (44.10%), wetland (25.50%) and a mix of forest (14.40%) and other uses (16.00%). This watershed has 325.68 stream miles, 3,484.83 lake acres and 20,071.57 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, Not Ranked 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.
Pensaukee River is considered a Macroinvertebrate, Warm Headwater, Warm Mainstem, COOL-Warm Headwater, COOL-Warm Mainstem under the state's Natural Community Determinations.
Natural communities (stream and lake natural communities) represent model resultsand DNR staff valiation processes that confirm or update predicted conditions based on flow and temperature modeling from historic and current landscape features and related variables. Predicated flow and temperatures for waters are associated predicated fish assemblages (communities). Biologists evaluate the model results against current survey data to determine if the modeled results are corect and whether biological indicators show water quaity degradation. This analysis is a core component of the state's resource management framework. Wisconsin's Riverine Natural Communities.
Warm Mainstem waters are moderate-to-large but still wadeable perennial streams with relatively warm summer temperatures. Coldwater fishes are absent, transitional fishes are common to uncommon, and warm water fishes are abundant to common. Headwater species are common to absent, mainstem species are abundant to common, and river species are common to absent.
Cool (Warm-Transition) Headwaters are small, sometimes intermittent streams with cool to warm summer temperatures. Coldwater fishes are uncommon to absent, transitional fishes are abundant to common, and warm water fishes are common to uncommon. Headwater species are abundant to common, mainstem species are common to absent, and river species are absent.
Warm Headwaters are small, usually intermittent streams with warm summer temperatures. Coldwater fishes are absent, transitional fishes are common to uncommon, and warm water fishes are abundant to common. Headwater species are abundant to common, mainstem species are common to absent, and
river species are absent.
