The Bureau of Reclamation has lowered the level of the river in Parker, AZ by approximately one foot in elevation. The drawdown will last for about two weeks.
Lake Moovalya is the proper name for the stretch of the Colorado River between Headgate Rock Dam and Parker Dam. Reclamation is coordinating this activity with the Bureau of Indian Affairs to allow the Colorado River Indian Tribes to perform annual maintenance on their canals.
The temporary drawdown began Monday and is expected to have minimal impacts on releases from Parker Dam. It will not affect Colorado River flows below Headgate Rock Dam (at BlueWater Resort & Casino).
During the drawdown, the Lake Moovalya water level will stay at approximately elevation 363.40 feet; the water level is normally at elevation 364.40 feet. The lake should return to its normal elevation by Tuesday, January 20, 2015. However, a return to normal elevation may occur sooner or later than this date depending on operational or environmental conditions.
All river users should be aware that fluctuating or lower than normal river flows may expose or create natural hazards such as moving sandbars, gravel bars, unstable riverbanks, floating or submerged debris, or other unfamiliar obstacles. As always, caution should be exercised while using the river.
