AQUATIC HABITAT AND FLOW CONDITIONS: During December 2013, Carmel
River streamflow at the MPWMD Highway 1 gage (HW 1) was 0 cubic-feet per second
(cfs). Lower river flows during December were not adequate for
migration or rearing for any life stage of steelhead. The river is dry to the Red Rock area
in mid-valley (RM 8.1) as well as an additional mile of stream between Boronda
Bridge and DeDampierre Park (RM 14.1).
Mean daily stream-flow at the District’s Carmel River at Sleepy
Hollow Weir gaging station varied from a high of 3.3 to a low of 2.5 cfs, which
resulted in a mean monthly flow of 3.05 cfs. Unimpaired runoff at San
Clemente Dam (SCD) for the month was 294 AF. Unimpaired
runoff at SCD for Water Year (WY) 2014, which started on October 1, 2013,
totaled 557 AF or about 7.9% of the long-term average of 7,044 AF.
During December 2013, 0.32 inches of rainfall were recorded at
California American Water’s (CAW) SCD. The rainfall total for WY 2014
(which started on October 1, 2013) is 1.06 inches, which is 15.6% of the
long-term annual average of 6.77 inches.
CARMEL RIVER LAGOON: In December 2013, the lagoon’s water-surface elevation (WSE)
rose from approximately 3.5 feet to 5.3 feet above mean sea due to wave overwash in the second half of the month (see graph
below). Surface inflow to the lagoon ceased on May 24, 2013.
Lagoon water-quality profiles were completed at five sites on
December 12, 2013. Temperature,
salinity, and dissolved oxygen levels were all in the “good” range for
steelhead rearing and the CO2 concentration improved since October,
dropping to 25 mg/l. The south-arm is
undergoing another red-algae and aquatic grass bloom.
LOWER RIVER STEELHEAD RESCUES: No rescues were
done in November or December. Staff
is continuing to monitor conditions at the river front.
