Water Quality Management Handbook
Water Source Drafting Flow Requirements
Effective Date: December 5, 2011
Fish Bearing Streams:
Do not exceed 350 gallons per minute for streamflow greater than or equal to 4.0 cubic feet per second
(cfs); do not exceed 20% of surface flows below 4.0 cfs; and, cease drafting when bypass surface flow drops below 1.5 cfs.
Non-Fish Bearing Streams:
Do not exceed 350 gallons per minute for streamflow greater than or equal to 2.0 cfs; do not exceed 50% of surface flow; and, cease drafting when bypass surface flow drops below 10 gallons per minute. Water sources designed for permanent installation, such as piped diversions to off-site storage, are preferred over temporary, short-term-use developments. Locate water drafting sites to avoid adverse effects to in-stream flows and depletion of pool habitat.
