AQUATIC HABITAT AND FLOW CONDITIONS: July’s flow conditions in the lower Carmel River
were poor for migration and generally 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 9.5
to 6.2 cubic feet-per-second (cfs) (monthly mean 7.3 cfs) resulting in 221
acre-feet (AF) of runoff, while flows at the Highway 1 gage dropped from 1.1 to
0.0 cfs (dry on July 14) (monthly mean 0.3 cfs), resulting in 17 acre-feet
(AF) of runoff.
No July 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 20.94 inches.
CARMEL RIVER
LAGOON: July water surface
elevations (WSE) dropped from approximately 7.6 to 6.3 feet above
mean-sea-level (see graph below).
Water-quality profiles
were conducted in mid-July at five lagoon sites. Water conditions in the main
body, north, and lower south arms were generally “fair” for steelhead rearing, down
to two meters depth, with water temperatures between 66 and 69 degrees
Fahrenheit, dissolved oxygen (DO) ranging from 1 - 14 mg/L, and low salinity
levels between 1 - 2 parts per thousand (ppt). Water quality below 2.0 m
was generally “poor” at all locations with lower DO and higher temperatures.
STEELHEAD RESCUES: Summer steelhead rescues started on
June 13, 2016 in the main-stem. By the end of July, 628 fish had
been rescued, including 408 young-of-the-year (YOY), 107 age 1+ year juveniles
(1+), 107 age 2+ year residents (2+). There were six mortalities (0.95%). Of the 628 rescued fish, 239 were from the drying
and isolated plunge pool below Los Padres Dam. They were released back into the
river ~100m downstream.
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 July
there were 380 steelhead at the Facility including 6 small YOY, 258 medium YOY/1+,
and 116 large 2+ fish in the Facility.
There were also three mortalities (0.78%).
