Special Notice for Storm Events

In the interest of utmost safety during the upcoming storm event(s), this notification is to advise you of a possible slight modification to the reservoir levels at Tulloch during these periods of significant rain/snow. Tri-Dam is working, along with the US Bureau of Reclamation to safely manage the reservoir levels and storm runoff, holding and releasing waters as necessary to ensure the safety of all persons along the Stanislaus River system including upcountry and downstream users. The current 2016 fall reservoir schedule for this year, as provided by prior notice is as follows:

FromThroughLowHigh
9/16/20169/22/2016506.0509.0
9/23/20169/29/2016504.7507.7
9/30/201610/6/2016503.5506.5
10/7/201610/13/2016502.2505.2
10/14/201610/20/2016500.9503.9
10/21/201610/27/2016499.5502.5
10/28/20163/20/2017498.6501.6

The reservoir is currently being operated within the range, as highlighted above 498.6’ to 501.6’. In conjunction with the US Bureau of Reclamation, Tri-Dam is planning to operate Tulloch Reservoir within this range, however, this advisory is being sent to advise you that, in the interest of extreme caution, it may be necessary to operate the reservoir as low as 498.0 feet in order to provide additional water storage space over the next two weeks. The purpose of the adjustment is to use the reservoir to store additional water, if needed and allow Tri-Dam to make metered downstream releases, as needed to prevent and/or minimize downstream flooding.

As always, even when the reservoir is managed within the ranges noted, actual elevations may vary temporarily due to inflow to Tulloch Reservoir during rain events, or unforeseen operational constraints. Residents and others operating in and around the reservoir should exercise care at all times.

In the event that you have any questions, please feel free to contact me.
