AQUATIC HABITAT AND FLOW
CONDITIONS: During May 2006,
During May 2006, the mean daily streamflow recorded at the District’s Carmel River Sleepy Hollow Weir gaging station averaged 139 cubic feet per second (cfs), and ranged from 85 to 225 cfs.
There were 0.89 inches of measurable rainfall in May as recorded by Cal-Am at San Clemente Dam (SCD), exceeding the long-term May average of 0.44 inches at this site. The rainfall total for Water Year 2006 to date is 27.62 inches, 131% of the long-term October-May average of 21.00 inches.
WSE at the
JUVENILE STEELHEAD RESCUES:
No fish rescues will be needed prior to July 1, 2006. Staff now
anticipates that flows will drop to ~ 10 cfs at the
SLEEPY HOLLOW STEELHEAD REARING FACILITY (Facility): Staff started seasonal maintenance activities at the Facility in May. An access road and gravel pad for the portable pump were repaired, annual power washing and set-up of the rearing channel was started, and the old round, T2 tank walls were removed to make way for the new fiberglass rearing troughs. Staff expects to have the Facility ready to receive rescued fish by early July.
ADULT STEELHEAD COUNTS AT
The end-of-February total of 124 was the lowest since District staff installed the automatic fish counter in 1994. Fortunately, several large late February/early March storms brought the river flow back up from very low levels and allowed a large pulse of adults to migrate upstream and over the dam to their upper spawning grounds. March’s total count of 175 adults was very favorable, but was not enough to reverse the downward trend in total annual number of adult fish passing over SCD since the 2001 season, when 804 fish were counted. April and May typically have fairly low adult counts at SCD, but persistent high river flows through April 2006 kept the fish run going strong. Only one fish was counted in early May. The 2006 year-to-date total of 345 fish has now surpassed last year’s total of 328 fish, but is still far below the 2001 high.
