Daniel, W.M, Infante, D.M, Herreman, K., Cooper, A., and Ross, J., 2019, National Fish Habitat Partnership (NFHP) 2015 Cumulative Habitat Condition Indices and Limiting Disturbances for the Conterminous United States linked to NHDPlusV1, (ver. 2.0, March 2019): U.S. Geological Survey data release,


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: The variables used to create indices in catchments vs. buffers differ due to differences in resolution of datasets. The [...]

These data were collected for multiple purposes. First, they were gathered in support of conducting a condition assessment of fish habitat in fluvial waterbodies throughout the conterminous United States in support of the National Fish Habitat Partnership (NFHP). Second, these data were intended to be made available to NFHP as well as other users interested in acquiring consistently-organized information over larger regions. This work was supported by local, state, and federal partners of NFHP, including the U.S. Fish and Wildlife Service and the U.S. Geological Survey. Because the condition assessment was conducted over such a large geographic region, we adopted a landscape approach for assessment which assumed that anthropogenic disturbances as well as natural characteristics in the watersheds affect a given unit of habitat which in turn would affect fishes. It was necessary to use a landscape approach because local measures of habitat or biological indicators of habitat condition are only available at a very small percentage of locations around the country while landscape data are available for every location in the United States.
