Trout Water 
Trout Waters are represented by Class I, Class II or Class III waters. These classes have specific ecological characteristics and management actions associated with them. For more information regarding Trout Classifications, see the Fisheries Trout Class Webpages.
Yes
Outstanding or Exceptional 
Wisconsin has designated many of the state's highest quality waters as Outstanding Resource Waters (ORWs) or Exceptional Resource Waters (ERWs). Waters designated as ORW or ERW are surface waters which provide outstanding recreational opportunities, support valuable fisheries and wildlife habitat, have good water quality, and are not significantly impacted by human activities. ORW and ERW status identifies waters that the State of Wisconsin has determined warrant additional protection from the effects of pollution. These designations are intended to meet federal Clean Water Act obligations requiring Wisconsin to adopt an 'antidegradation' policy that is designed to prevent any lowering of water quality - especially in those waters having significant ecological or cultural value.
No
Impaired Water 
A water is polluted or 'impaired' if it does not support full use by humans, wildlife, fish and other aquatic life and it is shown that one or more of the pollutant criteria are not met.
Yes

Fish and Aquatic Life

Current Use
The use the water currently supports. This is not a designation or classification; it is based on the current condition of the water. Information in this column is not designed for, and should not be used for, regulatory purposes.
Restricted Aquatic Life
Fish and Aquatic Life communities are not fully supported in this ecosystem.
Attainable Use
The use that the investigator believes the water could achieve through managing "controllable" sources. Beaver dams, hydroelectric dams, low gradient streams, and naturally occurring low flows are generally not considered controllable. The attainable use may be the same as the current use or it may be higher.
Cold (Class II Trout)
Streams supporting a cold water sport fishery, or serving as a spawning area for salmonids and other cold water fish species. Representative aquatic life communities, associated with these waters, generally require cold temperatures and concentrations of dissolved oxygen that remain above 6 mg/L through natural reproduction and selective propagation. Since these waters are capable of supporting natural reproduction, a minimum dissolved oxygen concentration of 7 mg/L is required during times of active spawning and support of early life stages of newly-hatched fish.
Designated Use
This is the water classification legally recognized by NR102 and NR104, Wis. Adm. Code. The classification determines water quality criteria and effluent limits. Waters obtain designated uses through classification procedures.
Cold
Streams capable of supporting a cold water sport fishery, or serving as a spawning area for salmonids and other cold water fish species. Representative aquatic life communities, associated with these waters, generally require cold temperatures and concentrations of dissolved oxygen that remain above 6 mg/L. Since these waters are capable of supporting natural reproduction, a minimum dissolved oxygen concentration of 7 mg/L is required during times of active spawning and support of early life stages of newly-hatched fish.

Overview

MULLET RIVER - T15N R22E Sec. 35, Stream Length = 39.7 miles.

The Mullet River originates from the outflow of Mullet Lake and the Mullet River State Wildlife Area in Fond du Lac County and flows in an easterly direction for approximately 40 miles to its confluence with the Sheboygan River in the Town of Sheboygan Falls, 17 miles upstream of Lake Michigan. The water quality of the Mullet River is considered good from its headwaters to Plymouth (approximately 25 miles) and fair from Plymouth downstream to its confluence with the Sheboygan River (approximately 15 miles) (WDNR 1968, 1995). The middle of the river, from Plymouth to Glenbeulah, has an increase in spring flow that lowers stream water temperatures and is classified as a Cold Water Community stream (trout). Upstream of Glenbeulah, and downstream of STH 67 near Plymouth, the Mullet River is classified as a Warm Water Sport Fish Community stream. This classification difference is due primarily to the increase in spring flow between Glenbeulah and Plymouth. The Mullet River is unique in that it flows from the warm water headwaters into a cold water segment. All of the other major tributaries in the Sheboygan Basin, including the Sheboygan and Onion Rivers, originate as coldwater streams and change over to warm water further downstream. The existing chemical and biological water quality information support the Mullet River's current biological classification. The river segment that flows through the Kettle Moraine State Forest Northern Unit, the Mullet Creek State Wildlife Area, and the Old Wade House State Park are located within the warmwater sport fish community segment.

MULLET RIVER WARM WATER SEGMENT DOWNSTREAM OF STH67 (RM 0-18.1) -

This reach extends from the confluence of the Mullet and Sheboygan Rivers upstream to State Highway 67 north of Plymouth. This 18.1-mile reach of the Mullet River is classified as a Warmwater Sport Fish Community stream. Water quality in this segment of the Mullet River is fair to good. Water chemistry and macroinvertebrate samples collected during 1994 indicate an increase in nutrients and solids from upstream to downstream but overall are not limiting the stream's biological potential. Point source dischargers as well as stormwater runoff, and cropland runoff result in increased nutrients, sedimentation, and bacteria to the stream. Fish barriers and water quality impacts from the New Paris, Meyer Park, and Plymouth dams present the greatest impact to the water quality of the Mullet River in this reach.

MULLET RIVER COLD WATER SEGMENT (RM 18.1-23.0)

The trout water reach of the Mullet River extends upstream from State Highway 67 to the confluence with Otter pond just downstream from Glenbeulah. This section of the Mullet River is the most heavily fished trout stream in Sheboygan County. Some agricultural pollution occurs within this segment, but is not considered limiting.

Water quality within this segment is rated as generally good, but is limited by a dam located at the Camp Evelyn Girl Scout facility. This impoundment alters the natural water temperature regime. The Northern Moraine Utility Commission wastewater treatment plant discharges to the groundwater of the Mullet River watershed. It is believed that after some treatment by the soil, the effluent mixes with the groundwater, which discharges directly to the Mullet River during part or all of the year. It is uncertain whether this occurrence is having an impact on surface water quality and bears investigation.

MULLET RIVER WARM WATER SEGMENT UPSTREAM OF GLENBEULAH (RM 23.0-39.7)

This segment starts at Otter Pond near Glenbeulah and terminates at Mullet Lake. The segment runs through the Kettle Moraine State Forest Northern Unit, the Mullet Creek State Wildlife Area, and Old Wade State Park.

Water quality conditions are good. There are fewer springs in this reach, combined with altered flows resulting from channelization and impoundments. Because of these limiting factors the fishery changes from trout stream to warm water sport fish. A dam forms the Glenbeulah Millpond, and two additional impoundments are present in the Mullet Creek Wildlife area to provide habitat for waterfowl.

Historical Description

The Wisconsin State Historical Society in conjunction with the Kohler Foundation is actively pursuing the restoration of The Historic Old Wade House's former sawmill, which is located along the Mullet River in Greenbush, Sheboygan County. The sawmill site was researched and an archeological dig was conducted during the last few years. The information collected will be used in the proposed reconstruction of the mill by providing insight into the construction of the original structure. In addition to the construction of the sawmill, the State Historical Society has proposed that this be a functioning sawmill, which would include reconstruction of the dam once located on the Mullet River. The current project proposal calls for the construction of the dam at the original site, but not an impoundment of the Mullet River (WWC 1997). An impoundment would be constructed adjacent to the Mullet River from which the mill would be operated. The Old Wade House project proposal and the Environmental Assessment (WDNR 1998) were discussed in a public meeting in 1998. The reports are available at the WDNR Plymouth Service Center.

The Department of Natural Resources (WDNR) had agreed to assist the State Historical Society in collecting information required for the environmental assessment of the project on the Mullet River. The WDNR conducted an aquatic resource survey of the Mullet River at the Old Wade House site, which included chemical and biological data collections (Aartila 1995), and stream flow (Galarneau 1998). Table 65 depicts the Mullet River sample sites for the basin monitoring and aquatic resource study.

The fish community in the Mullet River upstream from Glenbulah was assessed as part of the Old Wade House Project in 1994 and 1997. No recent surveys have been conducted in the trout river section nor lower river reaches. According to the results of the Hilsenhoff Biotic Index (HBI) This reach of the Mullet River has good water quality and very good biological diversity including rare mussel species (Table 68). The WDNR continues to work cooperatively with the State Historical Society with their proposed project at the Old Wade House State Park to help them obtain their unique project while protecting this special resource.

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.

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.

Watershed Characteristics

Mullet River is located in the Mullet River watershed which is 88.19 mi². Land use in the watershed is primarily agricultural (38.90%), forest (21.40%) and a mix of grassland (17.90%) and other uses (21.80%). This watershed has 97.54 stream miles, 789.87 lake acres and 6,609.38 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.

Natural Community

Mullet River is considered a Cool-Warm Mainstem, Cool-Warm Headwater under the state's Natural Community Determinations.

Natural communities (stream and lake natural communities) represent model results and 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.

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.

Fisheries & Habitat

MULLET RIVER COLD WATER SEGMENT (RM 18.1-23.0)

The fishery is represented by a good diversity of intolerant species, including brook and brown trout. The section of stream from Glenbeulah Springs to State Highway 67 is a Class II stream for brown trout and the diversity and number of individuals indicates a good fishery. The macroinvertebrate community is represented by a wide diversity of both intolerant and tolerant genera. The high water temperatures in the Camp Evelyn impoundment impair the trout habitat.

WDNR personnel surveyed the Mullet River downstream of the Crystal Lake Golf Course in August 1999. The fish community rated poor with species listed in Table ??? Stream habitat analysis showed excellent buffer area and shading; moderate streambank erosion; bottom substrate with a mixture of rock, gravel, and sand; and moderate fish cover. Benthic macroinvertebrate rating for this location were good to very good.

WDNR personnel surveyed a portion of the stream, upstream of County Highway “CJ” in July 2000. Land use in the area is heavily wooded with wetland areas in the riparian cooridor. The fish community rated fair with species listed in Table 51. Stream habitat analysis showed excellent buffer areas and shading, rocky substrate, and very little streambank erosion. Fish cover was limited due to shallow water depths.
