AQUATIC
HABITAT AND FLOW CONDITIONS: During
October 2013, Carmel River streamflow at the MPWMD Highway 1 gage (HW 1) was 0
cubic-feet per second (cfs). Lower river flows during October were
not adequate for migration or rearing for any life stage of steelhead. The river is dry nearly to Robinson
Canyon Bridge (RM 8.46) as well as an additional mile of stream between Boronda
Bridge and DeDampierre Park (RM 14.1).
In
order to conserve water storage in Los Padres Reservoir to sustain in-stream
flows through the ongoing drought, the Low Flow MOA minimum flow target in
October was dropped in two stages from 3.8 to 2.5 cfs. As a result, mean
daily stream flow at the District’s Carmel River at Sleepy Hollow Weir gaging
station varied from a high of 4.2 to a low of 2.0 cfs, which resulted in a mean
monthly flow of 3.1 cfs. Unimpaired runoff at San Clemente Dam (SCD) for
the month was 83 AF. Unimpaired runoff at SCD for Water
Year (WY) 2014, which started on October 1, 2013, totaled 83 AF or about 20% of
the long-term average.
During October
2013, 0.34 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 0.34 inches, which is 43.6% of the long-term annual average of 0.78
inches.
CARMEL
RIVER LAGOON: In October 2013,
the lagoon’s water-surface elevation (WSE) dropped from approximately 4.1 feet
to 3.5 feet above mean sea (see graph below). Surface inflow to the
lagoon ceased on May 24, 2013.
No
lagoon water-quality profiles were conducted in October, but surface water-quality
sampling indicated that water temperature and dissolved oxygen levels continued
to improve, at 16.6 degrees Celsius and 11 milligrams
per liter (mg/L) respectively, while the CO2 concentration continued
to rise to 35 mg/L.
LOWER
RIVER STEELHEAD RESCUES: No rescues were done in October.
