Army Corps of Engineers looking to drop Alamo Lake; opportunity for anglers/recreationists to provide comments by Feb. 10

Posted February 7, 2018

PHOENIX — The U.S. Army Corps of Engineers, Los Angeles District, has a draft Environmental Assessment for the Alamo Dam Flushing Flow Release available for public review and comment. According to a public notice issued by the Corps, it proposes to release water from Alamo Dam outside of the normal non-flood release schedule in order to facilitate required maintenance activities.

According to the public notice, the proposed release would occur as a flood pulse hydrograph designed to mimic a typical rain event in the downstream watershed released with appropriate seasonal timing. While the exact details of the release are subject to variation based on conditions at the time of release, such as water surface elevation and weather, the release will conform to the following general
parameters:

1) Maximum release will not exceed 5,000 cfs.
2) Total release time, including ascending and descending limbs, would not exceed 20 days.
3) Ascending limb of the hydrograph will be moderate.
4) Descending limb of the hydrograph will initially drop steeply, followed by a gradual return to base
flow.
5) The peak of the hydrograph will be completed prior to March 15th.

The Corps is soliciting comments from the public; Federal, state, and local agencies and officials; and
other interested parties in order to consider and evaluate the impacts of this proposed project and
alternatives.
