Texas Reservoir Recent Conditions: Storage and Percent Full (TWDB)

waterdatafortexas/reservoir-conditions

The latest conditions of every monitored Texas reservoir from the Texas Water Development Board's Water Data for Texas: for each lake the name, the day of the figures, storage and volume in acre-feet, percent full, current and conservation-pool elevation in feet, conservation capacity, surface area, tags for basin, region and use, and its map location as GeoJSON. Takes no input and returns all reservoirs (about 120). Passed through unmodified and served by Eden Engine; not an official Texas Water Development Board product.
