NFHP Data Download and Map Services


The NFHP Data System makes available data generated through the National Assessment efforts, as well as region-specific data, provided by Fish Habitat Partnerships (FHPs), and regional and national data from NFHP cooperators. This complimentary approach allows regional partners to benefit from national data efforts, while also helping fill region specific data gaps for future national efforts.

Habitat Condition and Disturbance Data from 2010 NFHP National Assessment

Inland Assessment of Streams

Stream Habitat Condition Index (HCI) scores generated as the result of the 2010 National Assessment are available at multiple spatial scales for the conterminous United States. HCI scores (local, network, and cumulative) and disturbance variable data are available for each confluence to confluence reach of the National Hydrography Dataset Plus Version 1 [NHDPlusV1]. HCI scores are also summarized so that Ecological Drainage Units [EDU], Hydrologic Unit Code [HUC] 8, and HUC12 are attributed with a single HCI for each spatial unit. Streams in Hawaii and Alaska were assessed using different spatial frameworks than those in the conterminous United States. HCI scores and disturbance indices for Hawaii are attributed to the National Hydrography Dataset (1:24k), while indices for Alaska are attributed to HUC12s. The scores from the inland assessment of streams can be explored at all scales using the National Assessment Results Viewer or downloaded for additional use.

        Coastal Assessment

        Coastal Habitat Condition Index (HCI) scores generated as the result of the 2010 National Assessment are available for the entire coastline of the conterminous U.S. The dataset includes the four subcomponent habitat condition indices, the final cumulative disturbance index, and all of the variables used to generate the indices. The coastal assessment can be explored using the National Assessment Results Viewer or downloaded for additional use.

          Fish Habitat Partnership (FHP) Datasets

          The amount of region-specific data made available by each of the Fish Habitat Partnerships' (FHPs) efforts is constantly growing. Select an FHP to see what datasets are currently available in the system.

            Datasets from Cooperators

            Efforts from cooperators have increased the access of available data to the National Fish Habitat Partnership. Additionally the transformation of select datasets has been conducted to link the data to the NFHP spatial framework, based on the NHDPlusV1 (1:100K). Providing these new data formats to the National Fish Habitat Partnership, partners, and stakeholders enables progress toward building consistent data nationally while reducing duplicative efforts.
