Muddy Creek Synoptic Study


Start Date
End Date


Muddy Creek, a tributary to the Little Snake River, is a semi-arid catchment that drains about 1,200 mi2 in south-central Wyoming. The drainage basin is characterized as a sagebrush steppe ecosystem. The area is undergoing energy exploration and development, including conventional natural gas wells and coalbed natural gas wells. Geologic formations that underlie the drainage basin include soluble marine shales, which are a natural source of dissolved solids (for example, sodium, chloride, and sulfate) and Se. As a result, the water quality of Muddy Creek is naturally high in dissolved constituents, including Se. The WDEQ has listed chloride and Se as impairments to aquatic life for Muddy Creek. Dissolved solids are a concern also because [...]
