SPL-2015-00010-KW Prado Dam Temporary Deviation

Published Nov. 25, 2015
Expiration date: 12/16/2015

The Orange County Water District (OCWD) has requested a temporary modification to the U.S. Army Corps of Engineers’ (Corps’) Water Control Plan for Prado Dam, to provide an opportunity for conserving additional water during the 2015/2016 flood season.  Currently, the authorized water conservation pool extends to an elevation of 498’ within the Prado Basin during the flood season (from October 1 through February 28), and 505’ during the non-flood season (March 1 through September 30).  Under flood control operations (during a major storm event), water may be held up to the current maximum basin elevation of 556’ as needed to allow for controlled releases.  The proposed modification to the Water Control Plan would not affect flood control operations, but would increase the allowable flood season water conservation pool to 505’ elevation. This increase in the water conservation pool during the flood season would provide approximately 10,500 acre-feet of additional storage space for conservation and groundwater recharge. While the proposed action (a one-year “deviation”) described in this notice is only for the remainder of the current flood season, the Corps and OCWD plan to pursue a five-year deviation that would be implemented at the beginning of next flood season.  Information developed through a monitoring program associated with the one-year deviation would assist in planning and evaluating any longer term actions.  The five-year or any other deviation or modification to the Water Control Plan would require separate environmental analysis and documentation.

The Corps of Engineers 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.                                                                                                                                                                                 

Comments will be accepted from November 25, 2015 to December 16, 2015.
