Dear Trinity River Enthusiasts -

Please be careful on the river this weekend as flows are increasing to
4,500 cubic feet per second (cfs) by Sunday night. Flows will continue to
rise Monday and will peak at 8,500 cfs on May 5th and 6th. The Dry year
hydrograph is shown below and is attached.

A total of 1,700 yards of clean gravel (1/4 inch to 5 inch diameter rocks)
will be added during Monday on the ascending limb of the hydrograph and at
peak flows on Tuesday. One thousand yards will be added at the Diversion
pool (aka the weir hole) and 700 yards will be added at the Lowden Ranch
site in Lewiston.
