In 2013 and 2014, standardized electrofishing was conducted above and below Lock and Dam 19 (i.e., in Pools 19 and 20 respectively) of the Upper Mississippi River (UMR). Sampling was consistent with the UMR Restoration program’s Long Term Resource Monitoring element (LTRM) and The Illinois Natural History Survey’s Long Term Electrofishing program (LTEF) allowing for standardized comparisons among the reaches we sampled and those sampled by the LTRM (Pools 4, 8, 13, and 26) and LTEF (Pools 16-21, and Pool 25). Data in this file is includes A) new data from Pools 19 and 20 and B) data compiled from public sources for other pools (LTRM and LTEF). Generally, data codes are intended to match formatting conventions from...

USGS Science Data Catalog (SDC),
The csv file includes all individual non-young-of-year fishes collected in unstructured channel borders of the Upper Mississippi River using daytime electrofishing from 1993 through 2015, following LTRM protocols. Data was collected via the Long Term Resource Monitoring element of the U.S. Army Corps of Engineers’ Upper Mississippi River Restoration program and the Illinois Natural History Survey’s Long-Term Survey and Assessment of Large-River Fishes in Illinois.

Lake Erie Biological Station (LEBS), located in Sandusky, Ohio, is a field station of the USGS Great Lakes Science Center (GLSC). LEBS is the primary federal agency for applied fisheries science excellence in Lake Erie. From 2011-2013, LEBS carried out a project which addressed the effects of regional climate change on aquatic food webs in the Great Lakes. This study focused on Lake Erie, as it is a representative system with a high level of anthropogenic impacts, strong nutrient gradients, seasonal hypoxia, and spatial overlap of cold- and cool-water fish guilds. In Lake Erie and in large embayments throughout the Great Lakes basin, this situation is a concern for fishery managers, as climate change may exacerbate...

Description of Work U.S. Geological Survey (USGS) scientists will conduct fish sampling in Indiana to determine the main causes of impairment of Pigeon Creek. The U.S. Environmental Protection Agency and Indiana State agencies will use the data to evaluate ways to improve water quality. Fish assemblage data is needed to develop total maximum daily loads and implementation plans for impaired AOCs and tributaries in the Basin. Development of the TMDLs will include determining the sources of the pollutant, calculating loading allocations to ensure the designated uses will be met, and developing an implementation plan to achieve these allocations. TMDLs will address several pollutants including nutrients, sediment and...

Data collected from 172 sites in 20 major river basins between 1993 and 1995 as part of the US Geological Survey's National Water-Quality Assessment Program were analyzed to assess relations among basinwide land use (agriculture, forest, urban, range), water physicochemistry, riparian condition, and fish community structure. A multimetric approach was used to develop regionally referenced indices of fish community and riparian condition. Across large geographic areas, decreased riparian condition was associated with water-quality constituents indicative of nonpoint source inputs—total nitrogen and suspended sediment and basinwide urban land use. Decreased fish community condition was associated with increases in...
