2020 Tulloch Spring Fill will follow the typical spring fill procedures, which follow the USACE flood control curve upward. During the spring fill, the reservoir will be managed to the given target elevation ranges as much as possible. Some variations may still occur due to large natural inflows or facility and operational constraints.

The fall drawdown schedule for Tulloch Reservoir is provided below. This schedule complies with U.S. Army Corps of Engineers flood control requirements. The reservoir will generally be managed to the target elevation range, however some variation may occur due to large local inflow during rain events or facility and operational constraints.

For further information, please see the Tulloch Reservior page.

Below is the 2019 Tulloch fill schedule, as just received from the Bureau of Reclamation. As always, the schedule is subject to substantial variation due to natural inflow during or after storm events. Please exercise caution when operating in and around the reservoir at all times.

The Spring 2018 Tulloch fill schedule will be done in two phases. The first phase will take place between February 1 and March 12, when the reservoir pool will be raised back to the normal winter elevation of 501.6 ft. The rate of fill will approximately follow the daily ranges below, but there may be substantial variations due to natural inflow or storm events. Since this phase of the reservoir fill is not governed by USACE flood control requirements, any extra inflow will be retained rather than released.

The second phase of the reservoir fill will follow the typical spring fill procedures, which follow the USACE flood control curve upward. During this phase, the reservoir will be managed to the given target elevation ranges as much as possible. Some variations may still occur due to large natural inflows or facility and operational constraints.

Phase 1: Elevation targets are approximate.

Phase 2:
