According to Susan Larson of Tri-Dam, "The testing of the spill gates at the dam
has been completed, as has the maintenance work which entailed painting
of the gates. The reservoir is in the process of being brought back to
the normal winter levels, as
specified by the schedule established by the Bureau of Reclamation."
'The Spring 2013 Tulloch fill schedule will be done in two phases. The
first phase will take place between February 8 and March 20, when the
reservoir pool will be raised back to the normal winter elevation of
501.6 ft. The rate of fill will approximately follow the daily ranges
below, but there may be substantial variations due to natural inflow or
storm events. Since this phase of the reservoir fill is not governed by
USACE flood control requirements, any extra inflow will be retained
rather than released.
The second phase of the reservoir fill will follow the typical spring
fill procedures, which follow the USACE flood control curve upward.
During this phase, 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.'
