Salt Creek's water quality is impacted by NPS pollution from residential areas
Salt Creek, a tributary of the East Arm Little Calumet River, flows through Indiana and Illinois, providing a habitat for several rare species. However, the creek's water quality has been a significant concern, with pollution from various sources, including residential areas, threatening the health of the aquatic ecosystem.
The Salt Creek watershed covers 19% of Porter County in Indiana, including the communities of Valparaiso, South Haven, Portage, and Burns Harbor. The creek's water quality is influenced by NPS (Non-Point Source) pollution, which originates from runoff and individual residential practices. Residential activities, such as washing cars in driveways, improper disposal of pet waste, and the use of herbicides and pesticides, contribute to NPS pollution. During heavy rain or snowfall, stormwater runoff carries these pollutants into the creek, impacting water quality.
The impact of NPS pollution from residential areas on Salt Creek's water quality is significant. The pollutants from residential sources can include oils, soaps, herbicides, pesticides, and excess fertiliser. These substances can contaminate the water, reducing visibility and blocking sunlight. Additionally, eroding stream banks, a consequence of uncontrolled NPS pollution, allow excess sediment to enter the stream, further degrading water quality.
To address the water quality issues in Salt Creek, a collaborative effort is required. The DuPage River Salt Creek Workgroup (DRSCW) was formed in 2005 to address concerns about TMDLs (Total Maximum Daily Loads) in Salt Creek and the East and West Branches of the DuPage River. The workgroup comprises local communities, publicly owned treatment works, and private environmental organisations. They work together to identify stressors to the aquatic systems and implement targeted solutions.
Additionally, the TMDL workgroup, including stakeholders from the Salt Creek and DuPage River watersheds, developed plans to improve water quality. They recognised that pollution in the streams, particularly after storm events, was a critical issue. By involving decision-makers from all affected communities, the workgroup aims to implement effective measures to reduce pollution and improve Salt Creek's water quality, ensuring the protection of the fragile environment and the diverse species that depend on it.

The watershed also contains wetlands and bog species like the tamarack, which are uncommon in Indiana. In recent years, the American badger and bobcat, which were once on Indiana's endangered species list, have been spotted within the watershed.
The Salt Creek tributary has faced issues with pollution. Non-point source (NPS) pollution, such as runoff from yards, storm runoff, and sewage treatment plants, has been a significant contributor to the water quality issues in Salt Creek. To address these issues, stakeholders from the communities in the watershed formed a TMDL workgroup in 2004 to develop plans to improve the water quality.
The Salt Creek watershed is also susceptible to overbank flooding every 2 to 3 years, which can impact the stream's aesthetic and recreational potential and pose threats to groundwater supplies. Floodplain management strategies, such as identifying floodplains and planning land use accordingly, can help mitigate the impacts of flooding in the area.
In summary, the Salt Creek watershed in Porter County, Indiana, covers 19% of the county and encompasses a diverse range of communities and natural habitats. The watershed is known for its rare species and historical trails, but it has also faced challenges with pollution and flooding. Through the efforts of local communities and organizations, there are ongoing initiatives to improve the water quality and preserve the fragile environment of Salt Creek.

The Salt Creek basin in Illinois experiences overbank flooding every 2 to 3 years
The Salt Creek basin in Illinois is a tributary to the Des Plaines River and is subject to overbank flooding every 2 to 3 years. This flooding is a result of the basin's location in a rapidly developing suburban area, with communities discharging treated sewage into the creek and storm runoff contributing to high water levels. The flood plains in this urban area need to be managed effectively to accommodate the floods, and measures such as controlled reservoirs and dam modifications have been implemented to mitigate the impact of flooding.
The Salt Creek Watershed Network (SCWN) has been actively involved in monitoring the creek and has observed the positive impact of community cleanups and projects aimed at reducing flood events. The Busse Dam Modification Project, for example, has significantly reduced flooding by allowing water to flow out of Busse Lake into Salt Creek before storms, creating additional capacity to hold rainwater. This has resulted in slower-rising water levels and lower crests during and after storms, reducing the severity of flooding.
While these flood control measures have been successful, the Salt Creek basin continues to face pollution problems. Sources of pollution include sewage treatment plants, storm runoff carrying pollutants from yards and roads, and erosion of stream banks. The high levels of pollution pose a threat to groundwater supplies and detract from the recreational and aesthetic value of the stream.
To address these issues, alternative approaches to water management and pollution reduction have been proposed. These include improving sewage treatment processes, detaining and treating storm runoff, and cleansing the streambed of accumulated sludge. By implementing these measures and effectively managing the flood plains, it is hoped that the Salt Creek basin can enhance its environment and reduce the impact of overbank flooding, which occurs regularly every 2 to 3 years.

The Salt Creek pupfish are adapted to the unique habitat of Salt Creek
Salt Creek, located in Death Valley National Park, California, is a unique environment. The creek is dry for most of the year, but during winter, flowing water returns to the otherwise arid landscape. Pickleweed plants, birds, and macroinvertebrates thrive in this temporary aquatic habitat. The Salt Creek pupfish (Cyprinodon salinus) are a small species of fish, typically only an inch or two in length, that are perfectly adapted to this ever-changing environment.
The Salt Creek pupfish are endemic to this small, isolated location and are currently classified as endangered. They are silvery with vertical dark bands on their sides, and during mating season, the males turn bright blue. The pupfish earned their name from their lively behaviour during spawning, which some people liken to playful puppies. They are well adapted to the harsh conditions of Salt Creek, which can see temperatures exceed 104 °F (39.4 °C). The pupfish can tolerate salt concentrations several times that of seawater, a remarkable ability that allows them to survive in this dynamic creek system.
The Salt Creek pupfish have evolved to take advantage of the cooler winter months to spawn. As summer approaches and temperatures soar, the pupfish retreat up the creek towards its spring-fed source to avoid perishing in the drying pools. While many Salt Creek pupfish perish each year as the creek evaporates, they are able to use the lower stretches of the creek for important parts of their life cycle. Their ability to thrive in such harsh conditions makes them a scientifically important species, as studying them could help scientists understand how other fish populations and streams may change due to climate change.
Salt Creek is facing threats from human activities in the region. Pollution from sources such as runoff from yards, car washing, and improper waste disposal is impacting the water quality. Efforts are being made to improve the situation, with stakeholders working together to address the issues and develop plans to enhance the water quality of the creek.
