This layer shows the aqueductsheds of L.A. County. Aquaductsheds are the watersheds outside the region from which we import water via human-made channels (aqueducts). L.A. draws water from the Owens Valley, Colorado River, and Northern California, often with adverse impacts to the health of the local ecologies and residents of those watersheds. With climate change placing increasing pressure on water supply systems across the American West, L.A. can reduce its dependency and impact on its aqueductsheds by collecting more local water supply.
The Aqueductsheds layer includes the following sublayers:
- Aqueductsheds
- Streams
- Aqueducts
1. Aqueductsheds
This sublayer shows the boundaries of the watersheds from which L.A. County imports water. This data is derived from NHDPlus High Resolution.
2. Streams
This sublayer shows the streams and natural pathways within each aqueductshed boundary. This data is derived from Watershed Boundary Dataset and NHDPlus High Resolution.
3. Aqueducts
This sublayer shows the aqueducts that transport water from the various aqueductsheds to L.A. County. This data is derived from National Hydrography Dataset.
