AQUATIC HABITAT AND FLOW CONDITIONS: During
November 2015, flow conditions in the lower Carmel River were inadequate for
migration of all steelhead life stages. Two
small storms led to brief localized streamflow at the
MPWMD Highway 1 (HW 1) gage but the river was never connected to the lagoon. Mean daily streamflow was 0.0 – 1.4 cubic
feet-per-second (cfs) with 3.0 total acre-feet (AF) of runoff, while flow at
the Sleepy Hollow Weir ranged from 2.3 to 4.8 cfs (mean 3.3 cfs) and 194 AF of
runoff.
By the end of November,
the lower Carmel River remained mostly dry to California American Water’s
(Cal-Am) Berwick Wells in mid-valley, at river mile (RM) 8.2. The 1.1 mile
reach between Boronda Road Bridge (RM 12.7) and DeDampierre Park is still dry,
but the river has rewetted the reach between upper DeDampierre Park and Rosie’s
Bridge (Esquiline Road, RM 14.45). All major tributaries below San Clemente Dam
(SCD) remained dry at their confluences with the Carmel River.
During November, 3.10
inches of rainfall were recorded at Cal-Am’s SCD gauge. The rainfall total
for WY 2016 (which started on October 1, 2015) is 3.99 inches, or 140% of the
long-term year-to-date average of 2.86 inches.
CARMEL RIVER
LAGOON: On December 12, 2014, the lagoon filled and
opened to the sea for the first time since May 24, 2013. After a final breaching in late March 2015,
the beach berm built up and the lagoon started slowly filling. The lagoon’s
water-surface elevation (WSE) in November ranged from 4.4 to 5.3 feet above
mean sea level (see graph below).
Water-quality profiles
were conducted in mid-November at five lagoon sites. Overall, conditions
remained “fair” for steelhead rearing with water temperatures dropping to the
low 50s degrees Fahrenheit, dissolved oxygen (DO) ranging from 0.1 - 11 mg/L,
and salinity levels ranging from 3 - 19 parts per thousand (ppt).
