Influence of a high head dam as a dispersal barrier to fish community structure of the Upper Mississippi River: Data 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... Categories: Data; Tags: Illinois, Impoundments, Missouri, Navigation Pool 19, USGS Science Data Catalog (SDC), All tags...

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.
