Dams affect river systems in a myriad of direct and indirect ways including disrupting the flow of water, energy, sediment, nutrients, and biota (e.g., Hammad 1972, Petts 1980, Williams and Wolman 1984, Cushman 1985, Bain et al. 1988, Ward and Stanford 1989, Benke 1990, Ligon et al. 1995). These changes impact lotic fish communities both through habitat alteration and fragmentation (Hayes et al. in press). Habitat alteration occurs upstream and downstream of dams, but in fundamentally different ways. Upstream from dams, the flow of water, sediment, and nutrients is slowed, creating impoundments and converting lotic habitat to lentic habitat (Petts 1980, Ward and Stanford 1989). This decreases habitat suitability...

This dataset represents results from this study attributed to the NHDPlus V2 catchments. Changes in climate occurring throughout the Mississippi River Basin are expected to lead to additional impacts in stream habitats and fish assemblages in multiple ways, including changing changing thermal properties and flow regimes. To manage streams for current impacts and future changes, managers need region-wide information for decision-making and developing proactive management strategies. Our project provides a suite of climate metrics that have been found to be relevant to the distribution and population structure of aquatic organisms in freshwater stream networks. These results provide natural resource managers, decision-makers,...

This CSV file contains cumulative fish habitat condition index (HCI) scores generated for river reaches of the conterminous United States as well as indices generated specifically for four spatial units including local and network catchments and 90 m local and network buffers of river reaches. Note that the cumulative HCI score is determined from limiting index scores generated for the four spatial units listed above. Detailed methods for calculating cumulative fish habitat condition index scores as well as the indices for each spatial extent can be found on the following website: http://assessment.fishhabitat.org/: The variables used to create indices in catchments vs. buffers differ due to differences in resolution...
