Comment on Dam Questions on CA’s Drought

This reporter doesn’t seem to understand that reservoirs lose water through evaporation, particularly when they get low (and thus warmer).  Other problems include methane production, due to decaying vegetation that is always being supplied by the streams flowing into them and by contributions from the reservoir margins.  They trap nutrients that otherwise would support coastal ecosystems. Unless managed to avoid such effects, they hinder the flushing of downstream river reaches, so that sediment buildup may bury gravelly pools and prevent fish spawning.
