AQUATIC HABITAT AND FLOW CONDITIONS: June’s flow conditions in the lower Carmel River were generally
poor for migration and fair to poor for rearing for all steelhead life
stages. Rearing conditions in the upper watershed were fair.
Mean daily streamflow at the Sleepy Hollow Weir dropped from 18 to
8.7 cubic feet-per-second (cfs) (monthly mean 11.8 cfs) resulting in 705
acre-feet (AF) of runoff, while flows at the Highway 1 gage dropped from 12 to 1.2
cubic feet-per-second (cfs) (monthly mean 4.1 cfs), resulting in 242
acre-feet (AF) of runoff.
No June rainfall was recorded at
Cal-Am’s San Clemente gauge. The rainfall total to date for WY 2016 (which
started on October 1, 2015) is 22.25 inches, or 106% of the long-term
year-to-date average of 20.92 inches.
CARMEL RIVER
LAGOON: June water surface
elevations (WSE) dropped from approximately 8.6 to 7.7 feet above
mean-sea-level (see graph below).
Water-quality profiles
were conducted in mid-June at five lagoon sites. Water conditions in the main
body, north, and lower south arms were generally “fair” for steelhead rearing
with water temperatures between 66 and 72 degrees Fahrenheit, dissolved oxygen
(DO) ranging from 3 - 10 mg/L, and low salinity levels (down to 2.0 meters
depth) ranging from 1 to 23 parts per thousand (ppt). Water quality in the
upper south arm was generally “poor” with lower DO and higher temperatures.
STEELHEAD RESCUES: Summer steelhead rescues started on
June 13, 2016 in the main-stem. By the end of June, 54 fish had been
rescued, including 11 young-of-the-year (YOY), 16 age 1+ year juveniles (1+),
26 age 2+ year residents (2+). There was
one mortality (1.84%).
Rescues were conducted
on the lower sections of three tributaries in late May/early June. A total of 245 fish were captured and
released into the Carmel River near the confluences. Hitchcock Creek – 175 fish
(mostly YOY); Robinson Canyon Cr. – 0 fish; Garzas Cr. – 70 fish (mix of YOY
and 1+ fish). There were also two mortalities (0.82%)
SLEEPY HOLLOW STEELHEAD
REARING FACILITY: The first rescued
fish were brought to the Facility on June 13, 2016. Through the end of June
there were 53 steelhead including 11 YOY, 16 1+, and 26 2+ fish in the
Facility.
