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.
Yes
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.
No

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.
Supported Aquatic Life
Waters that support fish and aquatic life communities (healthy biological communities).
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
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.
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

Black Earth Creek is a 27-mile long tributary to Blue Mounds Creek. The headwaters of the stream are heavily influenced by channelization and support only warm water forage fish. The rest of the creek, however, has a high fisheries value. The lower 11.5 miles support a warm water sport fishery that includes smallmouth bass although the section between Black Earth and Mazomanie may be able to be reclassified to cold water. Upstream from this warm water section, the stream is a cold water trout fishery and is fed by a series of spring complexes including a large cold water spring upstream from the Village of Cross Plains (Festge Springs) and numerous, other smaller springs. This stretch of Black Earth Creek is on the state's list of Outstanding and Exceptional Resource Waters (ORW/ERW) and supports a large population of naturally reproducing brown trout as well as a few native brook trout. The stream is stocked down stream with rainbow trout to increase additional opportunity for the anglers. A rare aquatic species has also been found in this stream during past stream surveys.

Overall, Black Earth Creek has high natural alkalinity, average temperatures that range from 40-65 degrees Fahrenheit, a substrate of rubble and gravel, and relatively stable flows these qualities combine to provide a highly productive aquatic ecosystem for the naturally reproducing brown trout population that exists in Black Earth Creek. As a result, the stream has been rated as one of the best 100 trout streams in the nation by Trout Unlimited. Public access is available at many road crossings and several village owned and WDNR properties. Despite its good quality, however, the entire stream is vulnerable to agricultural and urban runoff as well as permitted point source discharges.

Agricultural sources of runoff include cropland erosion, barnyard runoff and manure spreading on fields. Although this agricultural nonpoint source pollution has in many cases been addressed through the Priority Watershed Project for Black Earth Creek which is in its final stages, the stream is still at risk when these agricultural sources are poorly managed. In addition, the increasing development in the villages and in the watershed as a whole bring with it the threat of increased stormwater runoff and groundwater withdrawal. In particular, stormwater runoff from the Village of Cross Plains and other developments threaten the future of Black Earth Creek and its tributaries.

Historical Description

Black Earth Creek -Location of mouth T8N R5E Section 14 -12, Surface area -5.8 acres, Length = 1.8 miles, Gradient = 0.0 feet per mile, Total alkalinity = 240.0 mg/l, Volume of flow -14.3 cfs.

Most of this stream lies in Dane County and is described more thoroughly in the Dane County report. However, in Iowa County the stream has little gradient and it is wide and shallow throughout most of its length with a rather sterile sand bottom. It is considered one of the larger streams within the county and is the principal tributary of the Blue Mounds Creek, contributing approximately 38 percent of its total discharge. It is considered an excellent trout stream in Dane County where its principal water source is springs. The portion in Iowa County is not considered trout water but more suitable for northern pike, which are common. Forage fish species also known to be present are the emerald shiner, spotfin shiner
and white sucker. Waterfowl and marshland furbearers can be considered common throughout its length in Iowa County. There are no public lands along its banks and access within the county is from two town roads.

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.

Restore Wetlands
Need to protect wetlands in the Black Earth Creek watershed, particularly those that act as recharge areas for streams.

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

Black Earth Creek is located in the Black Earth Creek watershed which is 105.20 mi². Land use in the watershed is primarily forest (37.80%), agricultural (36.90%) and a mix of grassland (16.20%) and other uses (9.20%). This watershed has 196.86 stream miles, 204.29 lake acres and 1,541.75 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.

Natural Community

Black Earth Creek is considered a Coldwater 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.

Fisheries & Habitat

Due to its value as a fishery resource and its location, Black Earth Creek has been the focus of many other projects. Currently, there are three USGS gauging stations on the creek located at CTH KP at Cross Plains, on a tributary to the creek at Cross Plains, and at the Village of Black Earth. These stations provide real-time USGS data on the internet including flow,
river stage, and water temperature.
