White River Forum Ii: Second Annual Meeting Of The White River Forum, John Havel, Kenneth Steele
White River Forum Ii: Second Annual Meeting Of The White River Forum, John Havel, Kenneth Steele
Technical Reports
This second annual meeting of the White River Forum is proof of widespread interest in the water quality of the Upper White River watershed. The participation of numerous elected officials, state and federal agencies, universities, businesses, and local citizens indicates that interest in understanding policy issues crosses political boundaries and occupations.
Water Quality Sampling, Analysis And Annual Load Determinations For The Illinois River At Arkansas Highway 59 Bridge, 2008, L.B. Massey, L.W. Cash, B.E. Haggard
Water Quality Sampling, Analysis And Annual Load Determinations For The Illinois River At Arkansas Highway 59 Bridge, 2008, L.B. Massey, L.W. Cash, B.E. Haggard
Technical Reports
The Arkansas Water Resources Center monitored water quality at the Illinois River at the Arkansas Highway 59 Bridge, just upstream from the Arkansas-Oklahoma state border during base flow and storm events from July 1, 2008 through June 30, 2009. Water samples were collected manually or with an auto-sampler and analyzed for nitrate-nitrogen, ammonia-nitrogen, total nitrogen, total phosphorus, soluble reactive phosphorus, sulfate, chloride and total suspended solids. The U.S. Geological Survey recorded instantaneous stage and discharge at the site, total annual discharge was 1,010,000,000 m³ , with 37% attributed to base flow and 63% attributed to storm flow. Loads were estimated …
Water Quality Sampling, Analysis And Annual Load Determinations For Nutrients And Solids On The Ballard Creek, 2008, L.B. Massey, L.W. Cash, B.E. Haggard
Water Quality Sampling, Analysis And Annual Load Determinations For Nutrients And Solids On The Ballard Creek, 2008, L.B. Massey, L.W. Cash, B.E. Haggard
Technical Reports
The Arkansas Water Resources Center monitored water quality at Ballard Creek at the Washington County Road 76 Bridge in northwest Arkansas during base flow and storm events from July 1, 2008 through June 30, 2009. Water samples were collected manually or with an auto-sampler and analyzed for nitrate-nitrogen, ammonia-nitrogen, total nitrogen, total phosphorus, soluble reactive phosphorus, sulfate, chloride and total suspended solids. Instantaneous stage and discharge were recorded at the site; total annual discharge was 55,800,000 m³ , with 27% attributed to base flow and 73% attributed to storm flow. Loads were estimated using the mid-interval integration approach using continuous …
Frequency Distributions Of Median Nutrient And Chlorophyll Concentrations Across The Red River Basin, 1996-2006, S.D. Longing, B.E. Haggard
Frequency Distributions Of Median Nutrient And Chlorophyll Concentrations Across The Red River Basin, 1996-2006, S.D. Longing, B.E. Haggard
Technical Reports
Acquisition and compilation of water quality data for a ten year time period (1996 – 2006) from 589 stream and river stations was conducted to support nutrient criteria development for the multi–state Red River Basin shared by Arkansas, Louisiana, New Mexico, Oklahoma and Texas, USA. Twenty–three water quality parameters were collected from five data sources (USGS, ADEQ, LDEQ, OCC, OWRB, and TCEQ) and an additional 13 parameters were acquired from at least one source. Data for the primary biological parameter of interest, chlorophyll a, was sparse and available from only two sources. Following compilation of data, medians were calculated for …
