Tri-Dam has received additional updated information from the US Bureau of Reclamation (Bureau).  The Bureau advises that the current reservoir level range is likely to be maintained throughout the winter season as noted during our last update of September 21st, 2015.   Tulloch reservoir is currently being operated within the elevation range of  498′ to 501′, which is the normal winter holding elevation.  It is expected that the reservoir will be held within this range for the remainder of the winter season, until the fill schedule is produced in February/March 2016.  It is important to keep in mind however, that heavy rains and excessive runoff could cause Tulloch to rise above this level, if needed, to manage downstream flooding during heavy rain events.

This week’s update from the Bureau notes that the Bureau does not expect any change in the normal winter holding elevation at Tulloch  as noted above due to decreasing atmospheric temperatures, which are decreasing water temperatures downstream of Tulloch both at Goodwin and Orange Blossom.

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.

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

Tri-Dam has just received the following updated information from the US Bureau of Reclamation (Bureau).  It is important to note again that the Bureau has decided that this year’s drawdown schedule will be prepared in weekly increments, as they continue to monitor temperatures along the river system.  Tri-Dam will continue to send out these schedules immediately upon receipt.  In the event that conditions along the river system allow the Bureau to produce a longer length schedule, Tri-Dam will send that out immediately as well.  Continue to check our website at www.tridamproject.com

The drawdown schedule for Tulloch Reservoir is shown below for September 15-23, 2015 .   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.

The drawdown schedule for Tulloch Reservoir is shown below for September 8-15, 2015 . This schedule complies with U.S. Army Corps of Engineers flood control requirements. The reservoir will generally be managed within the target elevation ranges, but some variation may occur due to large natural inflows or facility and operational constraints. We will continue to coordinate with Tri-Dam and the Districts to determine the drawdown schedule and rate beyond September 15th and will be sending weekly updates.

While Tri-Dam continues to await the fall/winter draw down schedule from the Bureau of Reclamation (Bureau), the Bureau has just today opened the low level outlet at New Melones. They are slowly opening the outlet to the required level. The release of water will be balanced with releases from Tulloch, while continuing to monitor temperatures downstream from Tulloch. Given the weather forecast and late opening of the low-level outlet no changes at Tulloch are expected during the coming week. There is no anticipated change in water levels at Tulloch during this time period. Given this information, Tri-Dam continues to be optimistic that daily average normal operating levels at Tulloch (506.5’ – 509.5’) could be maintained through September 7, 2015. Please continue to watch this website for the actual schedule, which will be posted here immediately upon it’s receipt from the Bureau.
