Flow Scheduling
Forecasts | Allocations | Recommendations | Evaluations | Spreadsheet | Notifications
The amount of water available for the SJRRP, the Restoration Allocation, depends upon the amount of runoff in the San Joaquin River watershed above Friant Dam. Using several water supply forecasts for the Friant Division of the Central Valley Project, the SJRRP estimates the total unimpaired inflow below Friant Dam to determine an allocation. The Restoration Administrator uses the Restoration Allocation to make recommendations on the timing of releases based on river conditions and the specific goals and objectives at that time. Prior to an increase in flow rates, the SJRRP analyzes the likely effects on the river and surrounding lands and documents the results with a Flow Bench Evaluation. Following an affirmative evaluation, the SJRRP issues a notification and changes the releases.
SJRRP Allocations | Top

Operations Spreadsheet | Top
Reclamation maintains a detailed spreadsheet that aggregates publicly available gauge data and other operational conditions through the Restoration Area, tracks and accounts for Restoration Flows, and contains other information relevant to implementation of the Settlement. The SJRRP Operations spreadsheet includes real-time data as well as quality-controlled flow data, when available, for the gauging locations between Friant Dam and the Merced River confluence.

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, seepage losses, recirculation, recapture and reuse of flows.
