Water Quality Sampling, Analysis And Annual Load Determinations For Tss, Nitrogen And Phosphorus At The L'Anguille River Near Palestine, Marc A. Nelson, L. Wade Cash, Keith Trost, Jennifer Purtle
Water Quality Sampling, Analysis And Annual Load Determinations For Tss, Nitrogen And Phosphorus At The L'Anguille River Near Palestine, Marc A. Nelson, L. Wade Cash, Keith Trost, Jennifer Purtle
Technical Reports
A water quality sampling station was installed at the L’Anguille River near Palestine in 2003. This station is coordinated with a USGS gauging station at the same location. This station is instrumented to collect samples at sufficient intervals across the hydrograph to accurately estimate the flux of total suspended solids, nitrogen and phosphorus in the River. The L’Anguille River was listed on Arkansas' 1998 303d list as impaired from sediment (turbidity). The L’Anguille River was the second TMDL determined in Arkansas. Accurate determination of stream nutrients and sediment is critical for future determinations of TMDLs, effectiveness of best management practices …
Water Quality Sampling, Analysis And Annual Load Determinations For Nutrients And Sediment At The Arkansas Highway 45 Bridge On The White River Just Above Beaver Lake, Marc Nelson, L. Wade Cash, Keith Trost, Jennifer Purtle
Water Quality Sampling, Analysis And Annual Load Determinations For Nutrients And Sediment At The Arkansas Highway 45 Bridge On The White River Just Above Beaver Lake, Marc Nelson, L. Wade Cash, Keith Trost, Jennifer Purtle
Technical Reports
A water quality sampling station was installed at the Arkansas Highway 45 bridge on the White River just above Beaver Lake in 2002. This station is coordinated with a USGS gauging station at the same location. This station is instrumented to collect samples at sufficient intervals across the hydrograph to accurately estimate the flux of total suspended solids, nitrogen and phosphorus into the upper end of Beaver Lake from the White River. The West Fork of the White River is listed on Arkansas' 1998 303d list as impaired from sediment. The Upper White was designated as the states highest priority …
Water Quality Sampling, Analysis And Annual Load Determinations For Tss, Nitrogen And Phosphorus In The Bayou Bartholomew At Garrett Bridge, Ar And Near Portland, Ar, Marc A. Nelson, L. Wade Cash, G. Keith Trost, Jennifer Purtle
Water Quality Sampling, Analysis And Annual Load Determinations For Tss, Nitrogen And Phosphorus In The Bayou Bartholomew At Garrett Bridge, Ar And Near Portland, Ar, Marc A. Nelson, L. Wade Cash, G. Keith Trost, Jennifer Purtle
Technical Reports
Water quality sampling stations were installed at the Bayou Bartholomew at Garrett Bridge, AR and near Portland, AR. These stations are coordinated with USGS gauging stations at the same locations. These stations are instrumented to collect samples at sufficient intervals across the hydrograph to accurately estimate the flux of total suspended solids, nitrogen and phosphorus in the River. Bayou Bartholomew watershed is about 1.08 million acres and is located in the south east corner of the state. The land use in the watershed is mostly in forest and cropland agriculture with some urban area. High turbidity levels and excessive silt …
Water Quality Sampling, Analysis And Annual Load Determinations For Tss, Nitrogen And Phosphorus At The Washington County Road 76 Bridge On Ballard Creek, Marc A. Nelson, L. Wade Cash, G. Keith Trost, Jennifer Purtle
Water Quality Sampling, Analysis And Annual Load Determinations For Tss, Nitrogen And Phosphorus At The Washington County Road 76 Bridge On Ballard Creek, Marc A. Nelson, L. Wade Cash, G. Keith Trost, Jennifer Purtle
Technical Reports
The Illinois River Basin has experienced water quality impairment from non-point source pollution for many years. This fact was well documented in the State of Arkansas' Water Quality Assessment report, the Soil Conservation Service River Basin Study, and several University of Arkansas studies. Thirty-seven sub-watersheds have been identified by the SCS in the Arkansas portion of the Illinois River basin. In the Arkansas portion of the Basin, the Illinois River, Evansville Creek, Baron Fork, Cincinnati Creek, Muddy Fork, Moores Creek, Clear Creek, Osage Creek and Flint Creek were all classified as not supporting their designated use as primary contact recreation …
Water Quality Sampling, Analysis And Annual Load Determinations For Tss, Nitrogen And Phosphorus At The Washington County Road 195 Bridge On The West Fork Of The White River, 2004 Annual Report, Marc A. Nelson, L. Wade Cash, G. Keith Trost, Jennifer Purtle
Water Quality Sampling, Analysis And Annual Load Determinations For Tss, Nitrogen And Phosphorus At The Washington County Road 195 Bridge On The West Fork Of The White River, 2004 Annual Report, Marc A. Nelson, L. Wade Cash, G. Keith Trost, Jennifer Purtle
Technical Reports
A water quality sampling station was installed at the Washington County road 195 bridge on the West Fork of the White River just above the confluence of the three main forks of the Upper White River in December 2001. The Quality Assurance Project Plan (QAPP) was approved by EPA Region six on March 2002 and sampling was begun at that time. This station is coordinated with a USGS gauging station at the same location. This station was instrumented to collect samples at sufficient intervals across the hydrograph to accurately estimate the flux of total suspended solids, nitrogen and phosphorus into …
2004 Pollutant Loads Kings River Near Berryville, Arkansas, Marc A. Nelson, L. Wade Cash, Keith Trost, Jennifer Purtle
2004 Pollutant Loads Kings River Near Berryville, Arkansas, Marc A. Nelson, L. Wade Cash, Keith Trost, Jennifer Purtle
Technical Reports
An automatic sampler and a USGS gauging station were established in 1998 and water quality sampling was begun in 1999 on the Kings River near Berryville, Arkansas. Continuous stage and discharge measurements and frequent water quality sampling have been used to determine pollutant concentrations and loads in the river. This report presents the results from the sampling and analysis for January 1, 2004 to December 31, 2004.
Illinois River 2004 Pollutant Loads At Arkansas Highway 59 Bridge, Marc A. Nelson, L. Wade Cash, Keith Trost, Jennifer Purtle
Illinois River 2004 Pollutant Loads At Arkansas Highway 59 Bridge, Marc A. Nelson, L. 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, 2004 to December 31, 2004.
