Existing surface-water quality in the Twin Ponies watershed is significantly affected by runoff from agricultural lands that comprise most of the area. Runoff effects include the addition of phosphate, organic nitrogen, fecal bacteria, trace metals, pesticides and notably suspended sediment to streaMflow, because runoff commonly is a transport mechanism for these constituents. Low-flow water quality generally is characterized by dissolvedoxygen concentrations near saturation, dissolved-solids concentrations of about 450 milligrams per liter, suspendedsediment concentrations less than 200 milligrams per liter, and a pH of 8.2. However~ samples collected during runoff contained biological and chemical concentrations...

Generally, the water quality of Indian Creek-Van Buren watershed is suitable as a source of Municipal, industrial and agricultural water supply and for fish and wildlife. This suitability is based upon comparisons of the existing water quality of Indian Creek to Federal and State water quality standards and criteria developed for the protection of water sources and the fish and wildlife that inhabit these waters. The water in the basin is a calcium-magnesium-bicarbonate type that is low in dissolved solids. Concentrations of nutrients and metals, except iron, are low. Two pesticides, diazinon and dieldrin were detected in trace aMounts within the stream. Variations in water quality were evident from station to station...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
