Regional Board 7 - Colorado River Basin Region	CATEGORY 3	Final 2018 Integrated Report (CWA Section 303(d) List / 305(b) Report)
2018 CALIFORNIA WATERS WITH INSUFFICIENT INFORMATION TO ASSESS BENEFICIAL USE SUPPORT BUT SOME USES MAY BE POTENTIALLY THREATENED

Common Beneficial Uses Applicable California Beneficial Uses Aquatic Life Support Cold Freshwater Habitat, Estuarine Habitat, Fish Migration, Fish Spawning, Freshwater Replenishment, Inland Saline Water Habitat, Limited Warmwater, Marine Habitat, Preservation of Areas of Special Biological Significance, Preservation of Rare & Endangered Species, Warm Freshwater Habitat, Wetland Habitat, Wildlife Habitat Drinking Water Supply Municipal & Domestic Supply Fish Consumption Commercial or recreational collection of fish, shellfish, or organisms, Subsistence Fishing Secondary Contact Non-Contact Recreation Shellfishing Shellfish Harvesting Swimming Water Contact Recreation

Category 3 Criteria: A water with water quality information that is insufficient to determine an appropriate decision recommendation, but the available data and information that does exist indicates beneficial uses may be potentially threatened.

* USGS HUC = US Geological Survey Hydrologic Unit Code. Calwater = State Water Resources Control Board hydrological subunit area or even smaller planning watershed.
