AQUATIC HABITAT AND FLOW
CONDITIONS: During March
2014, Carmel River streamflow at the MPWMD Highway 1
gage (HW 1) was 0 cubic-feet per second (cfs).
However, a large storm in late February/early March filled Los Padres Reservoir
on March 1, 2014, allowing the riverfront to advance downstream to the Rancho
Canada Well (RM 3.13). The peak flow at
the USGS Robles Del Rio Gage (RM 15.78) reached nearly 700 cfs
while the Near Carmel Gage at Via Mallorca Road Bridge (RM 3.24) only reached
25 cfs on March 2nd and was dry again by
March 4, 2014 (see chart below). The
increase in flow was adequate for steelhead smolts and juveniles to begin their
downstream migration but not enough for them to reach the lagoon or ocean.
Mean daily streamflow in March at the District’s Carmel River at
Sleepy Hollow Weir gaging station ranged from 16 to 130 cfs,
with a mean monthly flow of 36.29 cfs. During March,
2.52 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 8.47 inches, or 44.8% of the long-term annual average (to
date) of 18.89 inches.
CARMEL RIVER
LAGOON: In March 2014, the
lagoon’s water-surface elevation (WSE) remained relatively stable, ranging from
approximately 5.2 to 5.6 feet above mean sea level (see graph
below). Surface inflow to the lagoon from the Carmel River ceased on
May 24, 2013. There was no river inflow
to the lagoon and the mouth remained closed during March.
LOWER RIVER STEELHEAD
RESCUES: Staff began steelhead smolt and juvenile rescues on March 3, 2014, the
earliest rescue start since 1991. As
of the end of March 1,092 fish had been rescued, including: 473 smolts, 617
non-smolted juveniles, and two 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 and impending flow increases which were
predicted to be high enough to damage the weir. During that time, 293 fish were captured
including: 91 smolts, 192 juveniles, and 1 adult.
