Not all Tailwaters are created equal. Some are bottom release only, some have multi level release, some are overflowing. Also, some are managed for power gen, some for ag, some for water supply... so release schedules and volume vary.Don't tailwaters stay colder assuming there is enough water released from dams or does the water heat up quickly a short distance from the dam? What do dams typically do in low water years? Do they cut flow, but agri gets their water, so the tailwaters get hot and have low flows just like freestone rivers?
