Why was Trinity Lake's control regulating discharge increased from 0 to 1,477 CFS on March 6 .. 20, 2023? (During historic drought in California.) What is "control regulating discharge"?
It seems difficult to justify discharge from either a consumption or flood control standpoint. Currently water consumption is low because of constant rains across the state, combined with strict irrigation limits due to continuing drought. While most large California reservoirs are at seasonal average capacity as of March 20, 2023, Trinity Lake is at only 50% of its average for this time of year. Most consumers have access to lower-altitude sources like Oroville (which is currently overflowing) and Shasta (which is just 70 miles downstream of Trinity and currently at seasonal average capacity). In this situation, wouldn't we expect water managers to retain water in high-altitude lakes, particularly the ones that are taking longer to fill up?
