Moonlight, you've just about got the 'facts"
100% correct. The area is high desert so the soil is not that deep, nor does it have a huge water holding capacity. Other thing that doesn't get into the mix is there are two other VERY large water impoundments above Klamath Lake.
"Whomever" is in charge of this water, so our local paper says, refused to release water for the river .... even though (again according to the local news) the impoundments had something like 90,000 acre feet of water sitting in them.
But no .......
