AQUATIC HABITAT AND FLOW
CONDITIONS: During July 2014,
Carmel River streamflow at the MPWMD Highway 1 gage (HW 1) was 0 cubic-feet per
second (cfs). As of July 31, the wetted front remained near Robinson
Canyon Road Bridge (River Mile, [RM], 8.46) with occasional isolated deep pools
in some reaches down to the Quail Lodge area (RM 4.3). An additional mile of stream was dry or
intermittent between DeDampierre Park and the Carmel Valley Trail and Saddle
Club (~RM 13.6).
Mean daily streamflow in
July at the District’s Carmel River at Sleepy Hollow Weir gaging station ranged
from 1.9 to 6.8 cfs, with a mean monthly flow of 3.95 cfs. During July, 0.0
inches of rainfall were recorded at California American Water’s (CAW) San
Clemente Dam (SCD). The rainfall total for WY 2014 (which started on
October 1, 2013) is 10.42 inches, or 49% of the long-term annual average (to
date) of 21.11 inches.
CARMEL RIVER
LAGOON: In July 2014, the
lagoon’s water-surface elevation (WSE) remained relatively steady between 2.8 -
3.4 feet above mean sea level (see graph below). Surface inflow to
the lagoon ceased on May 24, 2013. Since
that time, there has been no river inflow to the lagoon and the mouth has remained
closed.
Water quality profiles
were conducted in late July at five sites.
Water temperatures were quite warm, ranging from 72 - 78 degrees F,
dissolved oxygen (DO) levels were high at 9 - 22 mg/l, while salinity levels
remained low at 1.5 - 2.8 ppt.
Striped bass continue to
be an issue in the lagoon. The California Department of Fish and Wildlife
(CDFW) is conducting depletion fishing efforts.
LOWER RIVER STEELHEAD
RESCUES: Staff began steelhead smolt and juvenile rescues on March 3, 2014, the
earliest rescue start since 1991. By
the end of July, a total of 2,982 fish had been rescued, including: 873 smolts, 1,962 non-smolted juveniles, 142
young-of-year (YOY), and five adults. The
YOY fish are progeny from non-sea run spawning adults – possibly the large fish
released from the Sleepy Hollow Steelhead Rearing Facility last fall. The smolts and adults were acclimated to
seawater then released into the ocean at Stewart’s Cove, near the Carmel River
mouth. The juveniles and YOY were
transported farther upstream and released.
