Details
surveys: This dataset provides USFS Aquatic Organism Passage (AOP) survey data. It shows stream passage locations, passage measurements, and passability assessment categories from AOP field surveys. Structure included: culverts, dams, diversion dams, fords, and natural features such as waterfalls. activities: Activities included are where barriers to upstream migration have been improved. This includes improving existing passage structures or removing them entirely. Structures include culverts, dams, diversion dams, and fords. Also included are where structures have been added to purposely create barriers to protect native populations from invasive species. Data include the planned fiscal year and planned cost, the completed fiscal year, approximate completed cost, and partners involved. Each AOP activity is displayed as a single point. improved: Displays how far upstream from an activity on an Aquatic Organism Passage (AOP) structure that habitat has been improved. Data includes the completed fiscal year and lists species that benefit from the habitat improvement. The miles of habitat improved are displayed as a line or multi-line.
