Flow Scheduling Process
Based on preliminary water year forecasts in February and March, technical representatives of the Trinity River Restoration Program and program partners develop flow release recommendations to meet various restoration objectives and management targets listed in Chapter 8 of the Trinity River Flow Evaluation Final Report [PDF - 10mb]. Deliberations start with the typical flow release schedule recommended in the Record of Decision that may be adapted to meet specific restoration needs for the current year.
The flow recommendations are then presented to the Trinity Adaptive Management Working Group (TAMWG) and the Trinity Management Council (TMC) in late March or early April for consideration. The flow release recommendation approved by the TMC is then forwarded to the Bureau of Reclamation, which has the final authority over dam releases.
