U.S. Fish & Wildlife ServiceOverview This Feature Service presents detailed survey data of fish passage culverts in the Kake area. The primary layer documents observations and measurements of culverts and stream crossings, including physical dimensions, structure types, and conditions relevant to fish habitat and passage. Feature Layer: survey_CopyFeatures This layer contains comprehensive inspection records for culverts, including important information such as the number of culverts at a crossing, structure materials, road and stream details, and measurements like culvert length, inlet and outlet dimensions, water depths, and fill heights. Observations on hydraulic features, debris blockage, and visible deformations provide critical insight into culvert functionality. The data also records habitat conditions, fish species presence, and the severity of fish passage barriers. Multiple culverts at a single site can be cataloged with individual measurements for each, facilitating detailed assessment of complex crossings. Additional notes and photo documentation details augment the field observations. Geographic Coverage The dataset covers culverts and stream crossings within the Kake region, situated in Southeast Alaska. This localized geographic focus supports targeted environmental and infrastructural assessment efforts in this area.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/7666a76ab08048a2aa88ba23d6d427b1_0engU.S. Fish and Wildlife Service Open DataPublicKake Fish Passage Culvert Survey [United States]Web servicesUnited StatesLast Modified: 2026-04-28
