Dam Metrics Representing Stream Fragmentation and Flow Alteration for the Conterminous United States Linked to the NHDPLUSV1

This CSV file contains 21 dam metrics representing stream fragmentation and flow alteration for nearly 2.3 million stream reaches in the conterminous USA. Dam metrics fall into four main categories: segment-based, count and density, distance-based, and cumulative reservoir storage (described below). These data were developed using spatially verified large dam locations (n=49,468) primarily from the National Anthropogenic Barrier Dataset (NABD) that were spatially linked to the National Hydrography Dataset Plus version 1 (NHDPlusV1). These dam metrics have been summarized using the unique identifier field native to the NHDPlusV1 (COMID) which can be used to join this table to spatial layers and data tables of the...

National Fish Habitat Partnership (NFHP) 2015 Cumulative Habitat Condition Scores and Disturbance Indices for Hawaii Linked to Catchments of the Hawai'i Fish Habitat Partnership Stream Layer

This shapefile contains cumulative fish habitat condition index (HCI) scores and specific disturbance indices for local and network stream catchments as well as the downstream main channel catchment of perennial and intermittent streams reaches of the five main island of Hawai'i. In this dataset indices are linked to the Hawaii Fish Habitat Partnership (HFHP) stream layer (Tingley et al. in prep) which is a modified version of the 1:24,000 National Hydrography Dataset. It includes 11,436 intermittent and perennial stream reaches across the five main Hawaiian Islands (Hawai’i, Maui, Moloka’i, O’ahu, Kaua’i). Catchment attributes are available for both local catchments (defined as the land area draining directly to...
