February 2010 -- Interim Flows Update
The first interim release occurred in fall 2009 from October 1 to November 20. The spring flows began again on February 1, 2010 and will be ongoing through December 1, 2010.
The releases consist of a constant base flow of 350 cubic feet per second (CFS) and a series of pulses, with a modest pulse in the fall of 2009 and a longer duration, higher springtime pulse in 2010 that depends on the magnitude of winter rains and snowpack accumulation.
Most of the 2009 fall flow releases infiltrated into the ground in Reach 1 and 2, recharging the depleted groundwater aquifers.

The Bay Institute hydrologist Peter Vorster will be an integral part of the design, management and monitoring of the interim flows. He will assess and predict runoff and water supply conditions, analyze seepage losses, evaluate and refine the operational protocols, and ensure that the recapture and reuse of the restoration flows does not have an adverse impact on the restoration goal, downstream water quality or fisheries.
