PW/M&O RECEIVE A PRESENTATION UPDATE ON DROUGHT AND WATER SUPPLY DEPT. HEAD W CITYATTY. %1 1"^^&$&- CITY MGR. / M RECOMMENDED ACTION: Receive an updated presentation from the General Manager on Drought and Water Supply conditions. ITEM EXPLANATION: This informational report provides an update to current drought conditions in the Colorado Basin, California and the San Diego region. The report will also discuss potential water supply cutbacks and provide information related to the desalination project. FISCAL IMPACT: Several factors can influence revenue received by the District. These include water supply reductions, wet weather seasons, etc. Staff will monitor and analyze these, and other potential scenarios, throughout the year to determine financial impacts to the District. ENVIRONMENTAL IMPACT: Delta smelt, a species listed as threatened under the Endangered Species Act, have been impacted by State Water Project pumping. Recently, a U.S. District Judge has ordered the reduction of pumping by the State Water Project and/or the release of more water upstream of the State Water Project pumps in an attempt to establish temporary guidelines for the protection of the delta smelt and other fish species. The delta smelt are found in the Sacramento-San Joaquin River Delta in Northern California and the actions related to the reduction in State Water Project pumping do not have a direct local impact for Carlsbad.
