  • The Water Year (WY) 2010 Interim Flows Draft EA was available for public review through July 20, 2009 (extended from July 6).  This is a joint document that describes the direct, indirect and cumulative effects of the proposed WY 2010 Interim Flows Project.
  • The Settlement identifies the releases of both Interim Flows and Restoration Flows. The Settlement stipulates the release of Interim Flows beginning October 1, 2009, and continuing until full Restoration Flows begin.
  • The purpose of the Interim Flows is to allow the Implementing Agencies to collect relevant data concerning flows, temperatures, fish needs, seepages losses, recirculation, recapture and reuse of flows. 
  • This Water Year 2010 EA/IS describes and evaluates potential environmental consequences of the range of flows potentially released as Interim Flows in the San Joaquin River beginning October 1, 2009, to September 30, 2010. 
  • The EA/IS also describes the potential locations and mechanisms for recapturing WY 2010 Interim Flows within the San Joaquin River from Friant Dam to the confluence of the Merced River (Restoration Area), and in the Sacramento-San Joaquin Delta (Delta). In addition, associated actions that may be undertaken to collect relevant data during WY 2010 are discussed.
