For the purposes of keeping water, it wouldn’t be that useful.
The Klamath is far from major population centers, and is not currently part of any long-distance water transfer. (It’s been proposed but has actually been opposed by not only the local fisheries industry but by California.)
Also I think the grandparent is talking more about power generation; there needs to be a baseline level of water to generate power, and they already don’t generate a whole lot. Holding back water also means it isn’t getting used for power generation.
