AQUATIC HABITAT AND FLOW
CONDITIONS: During April
2014, Carmel River streamflow at the MPWMD Highway 1 gage (HW 1) was 0
cubic-feet per second (cfs). After retreating to the Quail Lodge area
(River Mile [RM] 4.5) in March, a storm in early April pushed the riverfront
back downstream to the Rancho Canada (RC) Well reach (RM 3.0) triggering a
second pulse of downstream smolt and juvenile steelhead migration to the front
(see USGS flow graph below). As of April
30, the front remained near the RC well site.
Mean daily streamflow in
April at the District’s Carmel River at Sleepy Hollow Weir gaging station
ranged from 14 to 45 cfs, with a mean monthly flow of 22.6 cfs. During April,
1.84 inches of rainfall were recorded at California American Water’s (CAW) San
Clemente Dam (SCD). The rainfall total for WY 2014 (which started on
October 1, 2013) is 10.27 inches, or 50.0% of the long-term annual average (to
date) of 20.53 inches.
CARMEL RIVER
LAGOON: In April 2014, the
lagoon’s water-surface elevation (WSE) slowly dropped from approximately 5.6 to
4.9 feet above mean sea level (see graph below). Surface inflow to
the lagoon ceased on May 24, 2013. There
was no river inflow to the lagoon and the mouth remained closed.
LOWER RIVER STEELHEAD
RESCUES: Staff began steelhead smolt and juvenile rescues on March 3, 2014, the
earliest rescue start since 1991. As
noted above, the river advanced downstream to the Rancho Canada Well reach two
times in 2014, forcing staff to re-rescue the same area as a large pulse of
smolts and juveniles became stranded at the front. By the end of April, 1,712 fish had been
rescued, including: 871 smolts, 837
non-smolted juveniles, and four adults.
The smolts and adults were acclimated to seawater then released into the
ocean at Stewart’s Cove, near the Carmel River mouth. The juveniles were transported farther
upstream and released.
STEELHEAD SMOLT TRAPP: Staff set up the smolt box-trap and weir on March 18, 2014. The purpose of the trap is to catch
downstream migrates before they reach the drying section of river. The trap was operated for eight days before
it had to be decommissioned due to permitting issues with the California
Department of Fish and Wildlife. The
trap was reinstalled on April 15 and has operated every day since. Through April 29, 538 fish were captured
including: 168 smolts, 822 juveniles, and 4 adults.
