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 inflows. This schedule incorporates an additional drawdown below the normal floor in order to permit required inspections and testing Tulloch Reservoir in January 2027. Starting in February 2027, the reservoir pool will be raised back to the normal winter elevation of 501.6 ft. The rate of fill will approximately follow the 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, an extra inflow will be retained rather than released.
