Regulatory Drivers For The Upper Illinois River And Other Regional Watersheds, Ray Weida
Regulatory Drivers For The Upper Illinois River And Other Regional Watersheds, Ray Weida
Technical Reports
Environmental regulations are put in place to protect the air, water and land from threat of pollution. Regulatory programs establish pollution limits, determine compliance, and enforce environmental laws and regulations for waterbodies within the watershed based on the designated uses for the individual waterbody. These established regulations make sure that the state’s mandatory standards for clean water and the minimum federal standards are being achieved. Environmental regulations are established on both the federal and state levels. On the federal level, Congress has authorized the U.S. Environmental Protection Agency and other governmental agencies to create and enforce regulations. The EPA delegates …

Water Quality And Watershed Conditions In The Upper Illinois River Watershed, Brian Haggard, Andrew Sharpley, Leslie Massey
Technical Reports
The Illinois River and its tributaries have many uses that have been designated by the Arkansas Department of Environmental Quality including fisheries, aquatic life, primary contact waters, secondary contact waters, drinking water supply, and agricultural and industrial water supply, and water quality affects whether these uses can be supported. Since water quality can be quite complex, many types of measurements can be used as water quality indicators; some common water quality measurements include pH, dissolved oxygen concentration, and conductivity. More complicated measurements include determining nutrients, sediment and bacteria in the water, as well as assessing the aquatic life—aquatic insects, fish, …
Illinois River 2006, Water Quality Assessment At The Arkansas Highway 59 Bridge, Marc A. Nelson, Wade Cash, Keith Trost, Jennifer Purtle
Illinois River 2006, Water Quality Assessment At The Arkansas Highway 59 Bridge, Marc A. Nelson, Wade Cash, Keith Trost, Jennifer Purtle
Technical Reports
Automatic water sampler and a U. S. Geological Survey gauging station were established in 1995 on the main stem of the Illinois River at the Arkansas Highway 59 Bridge. Since that time, continuous stage and discharge measurements and water quality sampling have been used to determine pollutant concentrations and loads in the Arkansas portion of the Illinois River. This report represents the results from the measurement and sampling by the Arkansas Water Resources Center -Water Quality Lab for January 1, 2006 to December 31, 2006.
Continuation Of Water Quality Monitoring Of The Osage Creek Above The Highway 112 Bridge Near Cave Springs, Arkansas, Marc Nelson, Luanna Diffin
Continuation Of Water Quality Monitoring Of The Osage Creek Above The Highway 112 Bridge Near Cave Springs, Arkansas, Marc Nelson, Luanna Diffin
Technical Reports
The City of Rogers is one of the fastest growing communities in Arkansas. Located in Northwest Arkansas, Rogers lies in two primary watersheds; the Illinois River Watershed and Beaver Lake Watershed. The Illinois River Watershed receives municipal wastewater discharge from most of the metropolitan communities in Northwest Arkansas, along with nonpoint source urban and agricultural runoff. The Illinois River originates in Arkansas and flows west into Oklahoma where it is classified as a scenic river. The river has been a source of interstate disputes for a number of years. A federal interstate compact commission was established to mediate these disputes, …

Illinois River Phosphorus Sampling Results And Mass Balance Computation, Marc Nelson, K.L. White, T.S. Soerens
Technical Reports
Phosphorus levels in the Illinois River are of great interest to the people of the States of Arkansas and Oklahoma. A great deal of effort has been expended to ascertain and modify the phosphorus impacts on the river. An automatic water sampling station was installed on the Illinois River just upstream from the State line in 1996 to accurately quantify the phosphorus in the Arkansas portion of the watershed. This paper summarizes five years worth of phosphorus sampling results at that site. In addition, a simple mass balance for phosphorus in the Illinois River Watershed above the sampling station was …
