Diversion Gate Trial Operation April 23

Current Opened Gates: Manually operated (gates #6, #9 (partial), and #14)

Gates were manually operated to wash away sediment deposited through the fish passage. Water depth was increasing up to 4.0 ft and then lowered 3.2 ft with gates opening

of #6, #9 (partial), and 14. According to Leonard, a gate operator, approximately 6 hours were taken to flush sediment (green circles, Figure 2 taken on 20-Apr).

Figure 3 shows after the flushing taken on 23-Apr.

GPS reading and water depth were in Table below. This calibration test was done in the south intake bay. Water depth was measured manually about 0.7 m. GPS reading does

not still transferred to data logger and computer.
