Streamflow and suspended-sediment discharge from two small watersheds in southwestern Wyoming and northeastern Utah, 1984

Accelerated erosion due to mineral exploration and production in southwestern Wyoming has caused concern that the streams will transport excess sediment in these areas. Two adjacent drainage basins with different levels of development were studied to determine the effects of minerals development on water quality. A high level of minerals development was occurring in the Thief Creek drainage basin; little or no development was occurring in the Chicken Creek drainage basin. Streamflow, suspended sediment , water temperature, and specific conductance data were collected at each creek from May through September, 1984. Water samples were analyzed for common characteristics and constituents, and for trace metals, iron, and manganese. (USGS)

Map showing flood of June 1972 resulting from tropical storm Agnes, Susquehanna River at Kingston, Pennsylvania

In June 1972, tropical storm Agnes caused severe flooding within a broad area extending from North Carolina to Southern New York. Flood elevations along the Susquehanna River were the highest ever recorded. In the Wilkes-Barre area, flood elevations exceeded those of 1865 and 1936 by about eight feet. Maximum discharges were about 40 percent greater than those of a 50-year flood. Property damages from flooding in the Wyoming Valley, in which Wilkes-Barre lies, far exceeded those in any are of similar size affected by the storm. The extent of the flooding on the map was delineated by the U.S. Geological Survey from field surveys made soon after the flood. Sections of levees and railroad grades that were not overtopped are not delineated.
