Report of completed reservoir sediment studies in Kansas using a combination of bathymetric surveying, sediment coring, chemical analysis, and statistical analysis to understand the quantity and quality of deposited sediment.
Water quality is important here because this reservoir is the primary supply for Wichita, Kansas. Due to low streamflow during the monitoring period, we expect suspended sediment and phosphorus to be more variable in the future.
Water from this reservoir will be used more extensively by the city, so we are developing methods of assessing the water quality in real time by measuring characteristics of stream flow that correlate with important water quality data.
We identified six compounds at concentrations less than human-health benchmarks, but within a factor of 10 of those limits. Those compounds might warrant further study to understand their transport and fate within the watershed.
The 258 organic compounds in this assessment are man-made: pesticides, solvents, gasoline hydrocarbons, personal-care and domestic-use products, pavement and combustion-derived compounds. None were found in concentrations deemed dangerous at this time.
In 2005, about 15.8 million gallons per day (Mgal/d) of water were withdrawn, including 4.12 Mgal/d from groundwater and about 11.7 Mgal/d from surface-water sources.Public supply use accounted for about 78 percent (12.4 Mgal/d) of the total water withdra
In 2005, about 9.52 million gallons per day (Mgal/d) of water were withdrawn, including about 9.33 Mgal/d from groundwater and 0.19 Mgal/d from surface-water. Public supply use accounted for 70% of the total.
