AQUATIC HABITAT AND FLOW
CONDITIONS: During May 2008, Carmel River
streamflow conditions were generally fair for downstream juvenile fish
migration, and juvenile fish rearing, and fair to poor for upstream and
downstream smolt and adult fish migration.
There was continuous, but low flow to the
Carmel River Lagoon.
During
May 2008, the mean daily streamflow recorded at the Monterey Peninsula
Water Management District’s (District’s) Carmel
River at Sleepy Hollow Weir gaging
station averaged 24.3 cubic feet per second (cfs) and ranged from 19 to 33
cfs. During May 2008, 0.0 inches of
rainfall were recorded at California American Water’s (CAW’s) San Clemente
Dam. The long-term average rainfall for
May at this location is 0.44 inches. The
rainfall total for Water Year 2008 to date is 19.61 inches, which is 93% of the
long-term average of 21.06 inches for the water year to date.
ADULT STEELHEAD COUNTS AT SAN CLEMENTE and LOS PADRES
DAMS: The fish counter was installed at the San Clemente Dam fish
ladder in December 2007 for the 2007-2008 season. The first upstream
migrating fish was counted on January 10, and the last one on April 14, 2008 (a
period of 95 days). A total of 412 steelhead were counted this season,
186% of the total 2006-2007 season, when approximately 222 adults were counted
through early April. The start of this year’s adult migration was
approximately four weeks earlier than the previous season due to the early
January storm and lagoon opening. The opportunity for further immigration
ended when the lagoon closed on April 29, 2008, and was probably restricted
after flows at Highway 1 declined below 40 cfs on April 12, 2008. This
year’s total is the highest since 2003, and near the mean for the last
decade. All fish are being digitally videotaped for future analysis.
A total of 158 adult steelhead have been counted passing
CAW’s Los Padres Dam fish trap and truck facility (the eighth highest number
since 1949). This number amounts to 38% of the fish that passed San
Clemente Dam. The run past Los Padres Dam began on February 12, and ended
on April 3, 2008 (a period of 51 days).
CARMEL RIVER LAGOON: The lagoon closed naturally on
April 29, 2008. To enhance steelhead
rearing habitat in the lagoon over the summer, California
State Parks crews fortified the sand berm with bulldozers on May 5, 2008, by
pushing beach sand to raise the berm elevation and prevent future
breaching. The lagoon filled over the
next eight days, reaching a water surface elevation (WSE) of 8.5 feet above
mean sea level (see charts below) before starting to slowly drop.
WSE at the Carmel River
Lagoon, April and May 2008
JUVENILE STEELHEAD RESCUES: District staff began its annual summer
juvenile steelhead rescues on May 14, 2008.
As of May 31, 2008, approximately 10,273 steelhead have been rescued
from the lower three miles of the Carmel
River between the Highway 1 Bridge and
Rancho Cañada Golf Course. Most of the rescued fish are
"young-of-the-year" (YOY) steelhead that were born this year and are
now about 1.5-2.0 inches long. All of these rescued steelhead were
transported to the District's Sleepy Hollow Steelhead Rearing Facility (Facility)
in upper Carmel Valley.
SLEEPY HOLLOW STEELHEAD REARING FACILITY: The first rescued fish were brought to
the Facility on May 14, 2008. As of May
31, 2008, approximately 10,218 fish (all but seven are YOY juveniles) are being
held in the rearing channel and quarantine tanks. So far, 33 fish have been lost during their
initial quarantine periods and 22 fish have died during rearing, for a total
mortality rate to date at the Facility of 0.5%
