AQUATIC HABITAT AND FLOW CONDITIONS: Following another dry
month, Los Padres Reservoir remained
nearly full, but still failed to spill leading to two more reductions of
outflow down to 14.1 cubic-feet-per-second (cfs). Lower river
rearing conditions for juvenile steelhead remained fair all the way to the
lagoon, but low flows continued to limit upstream migration opportunities.
Mean daily streamflow at the Sleepy Hollow Weir ranged from 20 to 23
cfs (monthly mean 20.5 cfs) resulting in 1,140 acre-feet (AF) of runoff,
while mean daily streamflow at the Highway 1 gage ranged from 14 to 17 cfs
(monthly mean 15.6 cfs), resulting in 865 AF of runoff.
There were 1.11 inches of rainfall in February as recorded at
Cal-Am’s San Clemente gauge. The rainfall total for WY 2018 (which started on
October 1, 2017) is 6.08 inches, or 39% of the long-term year-to-date average
of 15.43 inches.
CARMEL RIVER
LAGOON: The lagoon was breeched by the county on January 9 and again on January
21 after waves rebuilt the sandbar. After a period of opening and closing with
the tides, the mouth closed on February 11 for the remainder of the month,
slowing filling to 11.5 feet above
mean-sea-level (see graph below).
Water quality
depth-profiles were conducted at five sites on February 1. The lagoon mouth was
open, inflow was 17 cfs, and waves were overtopping the sand berm at the time
of the sampling. Salinity level varied with depth (2-30 ppt), temperature ranged from (50-56 degrees F), and dissolved
oxygen (DO) levels were good throughout the lagoon (7-12 mg/l) resulting in “good
to excellent” steelhead rearing conditions.
LOS PADRES DAM ADULT
COUNTS: Cal-Am maintains a
fish ladder and trap at the Los Padres Dam site. All adult steelhead captured
in the trap are trucked to the reservoir and released. As of February 28, one
resident adult trout have been captured and moved above the
dam. No sea-run steelhead adults have been observed yet. The downstream
smolt bypass facility was activated on February 8th.
