AQUATIC HABITAT AND FLOW CONDITIONS: Streamflow conditions for fish migration were excellent for adults in February 2010, and optimal for smolts and juvenile fish with continuous flow to the lagoon throughout the month.
During February, the mean daily
streamflow recorded at the District’s
ADULT STEELHEAD AT SCD: The fish counter and video camera were
installed at the ladder on October 17, 2009.
The first fish recorded over the counter was on October 17. As of February 28, 2010, a total of 90 fish have
been recorded passing the counter, including two in October, five in November,
three in December, 25 in January, and 55 in February (see graph below). By the end of February 2010, 21 fish were reported
at Cal-Am’s Los Padres Dam Fish Trap (see graph below). These numbers nearly match the total counts
for the whole season seen at these locations in 2009, and we are still a week from
the normal mid-point of the run, which indicates a significant recovery from
last year’s lows.
