Tulloch Reservoir Update – September 21, 2015

Anticipated Final Tulloch Reservoir Schedule

Tri-Dam has just received the following updated information from the US Bureau of Reclamation (Bureau).  Please note that the Bureau has prepared this schedule to bring the reservoir to the 498’ to 501’  elevation range by September 26, 2015.  This is the normal winter holding elevation, and it is expected that the reservoir will be held at this elevation through the remainder of the winter season, until the fill schedule is produced in February/March 2016.  Should the regulatory agencies determine that additional drawdown is necessary, Tri-Dam will provide immediate notification.  Although the current schedule is expected to remain in effect, it is important to continue to watch for updates and check the website periodically at www.tridamproject.com

This schedule complies with U.S. Army Corps of Engineers flood control requirements.  The reservoir will generally be managed to the target elevation ranges, but some variation may occur due to large natural inflows or facility and operational constraints.  As always, please exercise care when operating in and around the reservoir.
