difficulties with screen operations and insufficient ri ver flows to supply water to operate the fish
bypass pipe, Some deficiencies were experienced during operation and were remedied as they
occurred, Other deficiencies were noted and will be fixed during the winter prior to the 2003
irrigation season,

The biggest problem needing to be fixed is the unequal flow distribution along the screen,
The first portion of the screen has very little flow going through it. The middle has about normal
flow while the last third has very high flow, This problem appears to be associated with the way
the water bends into the canal at the canal head gates, The Bureau of Reclamation hydraulics lab
in Denver, Colorado, is currently modeling the fish screen and canal in order to determine the
optimum canal configuration to distribute the flow more evenly over the fish screen,

An operation and maintenance contract between GVrC, FWS and USBR for the fish
screen was also executed,

VIII, Recommendations:

Continue working with the GVIC to remedy screen operational problems, Reclamation
will work with GVIC to determine the best method to fix uneven distribution problems. rf
possible, canal improvements will be made before the 2003 irrigation season.
