Sedimentation and occurrence and trends of selected chemical constituents in bottom sediment of 10 small reservoirs, Eastern Kansas

Sedimentation, sediment quality, and upstream channel stability, John Redmond Reservoir, east-central Kansas, 1964-2009

“…Among the reservoirs compared, the sediment yield for John Redmond Reservoir was relatively low. In an analysis performed in 2004 that included 11 reservoirs listed in table 5 (Fall River Lake and John Redmond Reservoir excluded), a statistically significant positive correlation (significant at the 0.001 level) between sediment yield and mean annual precipitation (Spearman's rho = 0.86) was indicated (Juracek, 2004b). Thus, for the 11 reservoirs included in the analysis, mean annual precipitation was the best predictor of sediment yield.…”

“…All or most arsenic, chromium, and nickel concentrations were greater than the respective threshold-effects guidelines. Sediment concentrations of arsenic, chromium, and nickel greater than the respective threshold-effects guidelines are typical for reservoirs in eastern Kansas (Juracek, 2003(Juracek, , 2004b(Juracek, , 2008Juracek and Mau, 2002). For these three trace elements, the measured concentrations may be indicative of natural contributions from soils and bedrock (Luoma and Rainbow, 2008).…”

Assessment of sediments in the riverine impoundments of national wildlife refuges in the Souris River Basin, North Dakota

“…Impoundments created by obstructing river flows, however, often have a finite life span because they accumulate sediments that result in loss of water storage capacity (Smith and others, 1960;Gleason and others, 2003a;Juracek, 2004;Lee and others, 2008;Graf and others, 2010;Juracek, 2010;Juracek, 2011). Sedimentation is a natural process, but infrastructure that slows and impounds water flows tends to accelerate sedimentation rates in localized areas upstream from structures (for example, levees, dams) and accelerate erosion downstream from structures.…”

Quality characteristics of ground water in the Ozark aquifer of northwestern Arkansas, southeastern Kansas, southwestern Missouri and northeastern Oklahoma, 2006-07

“…Commercial lead-and-zinc mining in the Mississippian-age rock formations of the Springfield Plateau aquifer occurred from about 1870 to 1970 in the area of southeastern Kansas, southwestern Missouri, and northeastern Oklahoma known as the Tri-State Mining District (Gibson, 1972). The legacy of this long mining history includes trace element (cadmium, lead, and zinc) contamination of large areas of the Springfield Plateau aquifer (Barks, 1977;Playton and others, 1980;Spruill, 1987) and surface-water sources (Bailey, 1911;Pope, 2005;Juracek, 2006;Angelo and others, 2007).…”
