West Bank Erosion 01-Feb-07

 

West bank erosion was found downstream of the diversion structure.

Gate #24 (20 ft long), #4, and 5 were lowered and gate #3 was partially lowered on 31-Jan-07.  This configuration maintained the 3 ft design water depth (4995 el. ft) as shown on the PLC screen.  Some erosion was found on the west bank downstream of gate #24.

On 01-Feb-07, gate #22 (20 ft long) was opened instead of #24.  The 4995 ft design water level was maintained in this configuration.
