California Bay-Delta Environmental Enhancement and Water Security Act

California Bay-Delta Environmental Enhancement and Water Security Act - Authorizes appropriations for FY 1998 through 2000 for the initial Federal share of the cost of developing and implementing: (1) a specified portion of an ecosystem protection plan for the San Francisco Bay Sacramento-San Joaquin Delta Watershed (Bay-Delta) in California; and (2) the ecosystem restoration elements of the long-term California-Federal Bay-Delta Program. Requires such appropriated funds to be administered in accordance with procedures established by such Program until the Congress authorizes an entity recommended by the Program to carry out this Act.

Requires funds authorized to be appropriated to agencies that are currently or that subsequently become Program participants to be in addition to the baseline funding levels established in this Act for currently authorized projects and programs under the Central Valley Project Improvement Act and other currently authorized Federal programs for the purpose of Bay-Delta ecosystem protection and restoration.

Authorizes agencies and departments that are or that become participants in the Program to undertake the activities and programs for which Federal cost sharing is provided by this Act. Requires the United States to immediately initiate coordinated consultations and negotiations with California to expeditiously execute a specified cost-sharing agreement signed by its Governor on July 11, 1996.

Directs the Office of Management and Budget to submit to the House and Senate Committees on Appropriations, as part of the President's FY 1998 Budget, an interagency budget crosscut that displays Federal spending for FY 1993 through 1998 on ecosystem restoration and other purposes in the Bay-Delta Region, separately showing funding provided previously or requested under pre-existing authorities and new authorities granted by this Act.
