These data are the primary data used to estimate rainbow trout abundance and survival in the Colorado River, Glen and Grand Canyons. Refer to the analyses as per the associated journal manuscript (see Larger Work Citation). Prey availability, feeding efficiency, and competition reduce somatic growth and cause the collapse of a fish population" Nighttime boat electrofishing was used to sample rainbow trout four times per year in April, July, September, and January, from April 2012 through September 2016. A total of five reaches were sampled between Glen Canyon Dam (river kilometer [rkm] 0) to below the confluence with the Little Colorado River (located at rkm 130). Reaches ranged from two to six km in length. A total...

In 2006, the U.S. Geological Survey (USGS), in cooperation with the Texas Department of Transportation, began collecting annual and approximately quarterly-series peak streamflow data at streamflow-gaging stations in small- to medium-sized watersheds in central and western Texas, along with selected flood-hydrograph data at a subset of these stations. The data were primarily collected from a type of USGS streamflow-gaging station known as a crest-stage gage (CSG) station. The CSGs record peak stage, or maximum gage height (elevation of water surface above a local vertical datum), at the stations during storm events. Established and widely-used indirect methods of peak streamflow estimation, such as culvert-flow,...
