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...

The SARP Flow Alteration Assessment provides a regional characterization of the distribution and risk of flow regime impairment of streams and rivers by anthropogenic sources at the NHD+ segment scale. This map illustrates the risk of flow alteration (RFA) due to evaporative loss from artificial water bodies in local catchments for the 14-state SARP region. Â The amount of water body surface is based on high resolution NHD and linked to NHD+ catchments. Â The risk is based on the percentage of the catchment land surface covered by artificial water bodies (100 x water body surface area / watershed surface area) Risk of flow alteration categories: Â Â Â Â Â Â Â Â Â ZERO -Â Â Â Â Â Â 0% land covered by artificial...
