The water coming out of the bottom of the dam was cold, which trout like, but nearly devoid of oxygen.
The disused Melones Dam blocks cold water at the bottom of the lake from reaching the river, especially in dry years when the surface of the lake is closer to the crest of the old dam.
Static ice loads (ice actions) are a key design parameter for dams in cold climates.
"In the past," Pierce said, "in late summer, when dissolved oxygen levels got low in the reservoir, the water was coming out of the bottom of the dam nice and cold but was nearly devoid of dissolved oxygen.
The aim of this applied research was to evaluate the in situ performance of field-moulded joint sealants (FMSs) in dams situated in cold climates.
The water the dam releases is clear and cold (drawn from the depths of the lake), which is just the thing for nonnative trout, but bad news for homegrown chubs and suckers, which evolved, quite literally, in the murk of ages past.
Thus, in especially dry and cold years, the dams are likely to produce less electricity, which could result in high electricity prices and the need to import power.
For this, we refer to dam development in Afghanistan during the Cold War institutional constellation, which combined with the discourse on the role of dams in state formation, modernisation and development, profoundly shaped Afghanistan's landscape.
Clear, cold water released by dams has significantly changed characteristics of habitat for these and other Colorado River basin fishes.
