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.
