Tulloch Spring 2021 Fill Schedule

From: Bureau of Reclamation

2021 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 reservoir schedule for Tulloch Reservoir is prepared by the Bureau of Reclamation (BOR). The BOR operates New Melones and generates power at the power house directly upstream from Tulloch Reservoir. Although Tri-Dam and the BOR work to stay within the posted range, there are many factors that can cause reservoir levels to periodically be “out of range”. Such factors include power generation equipment availability, electric grid management, mandated and emergency river releases for fisheries and other environmental factors. When this occurs, both Tri-Dam and the BOR work to jointly manage reservoir operations at Tulloch and New Melones to get back into the posted range as quickly as safely possible. For this reason, we again remind residents and others that the reservoir levels are subject to change daily and seasonally, thus it is necessary to monitor facilities daily particularly during the spring fill and winter drawdown.
