Colorado River Water Temperature Modeling Below Glen Canyon Dam
The study presents an analysis of Colorado River temperature modeling below Glen Canyon Dam, Arizona. The potential of raising the water release temperatures at the dam by modifying dam penstocks with multiple-level reservoir intakes is discussed. Predicted temperatures of waters drawn from Lake Powell by such intake structures are calculated with a computer model for both four and eight modified penstocks. The temperature change of this warmer water as it moves downstream through the Grand Canyon is then evaluated using both a computer-generated temperature function and a simplified graphical method. Multiple-level intake structures on all eight of Glen Canyon Dam's penstock intakes would increase river temperatures, but not to pre-dam levels. The river temperature models calculate only a modest increase in water temperature from Lees Ferry to Diamond Creek.
