AQUATIC
HABITAT AND FLOW CONDITIONS: During
January 2014, Carmel River streamflow at the MPWMD
Highway 1 gage (HW 1) was 0 cubic-feet per second (cfs). Lower
river flows during January were not adequate for migration or rearing for any
life stage of steelhead. The
river remained 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 ranged from 3.8 to 3.0 cfs,
with a mean monthly flow of 3.3 cfs.
During
January 2014, 0.02 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 1.08 inches, or 9.7% of the long-term annual average (to
date) of 11.17 inches.
CARMEL
RIVER LAGOON: In January 2014,
the lagoon’s water-surface elevation (WSE) remained relatively stable, ranging
from 4.7 to 5.4 feet above mean sea level (see graph below). Surface
inflow to the lagoon ceased on May 24, 2013.
Lagoon
water-quality profiles were completed at five sites on January 13, 2014. Due to wave overwash
in December, lagoon salinity levels increased significantly to 10-12 parts per
thousand. Temperatures were consistent at all sites, at approximately 9 degrees
C, while dissolved oxygen (DO) levels ranged from 7-9 milligrams per
liter. Both temperature and (DO) levels
at all sites were in the “good” range for steelhead rearing. At site S2 (south arm), a thermocline at 1.5 meter depth caused the temperature and
salinity to increase with depth while DO decreased.
LOWER
RIVER STEELHEAD RESCUES: No rescues were done in January. Staff is continuing to monitor conditions at the
river front.
