AQUATIC HABITAT AND FLOW CONDITIONS: Carmel River flows held relatively steady in August
with conditions for juvenile steelhead migration fair to poor and rearing
conditions good to fair for young-of-the-year. Los Padres Dam (LPD) stopped
spilling on August 2nd and releases from Los Padres Reservoir have
been held at 15 cfs since August 3.
Mean daily streamflow at the Sleepy Hollow Weir ranged from 19 to 17
cfs (monthly mean 18.4 cfs) resulting in 1,130 acre-feet (AF) of runoff.
Mean daily streamflow at Highway 1 gage ranged from 8.8 to 6.3 cfs (monthly
mean 7.54 cfs), resulting in 464 AF of runoff.
There were 0.00 inches of rainfall in August as recorded at
Cal-Am’s San Clemente gauge. The rainfall total for WY 2017 (which started on
October 1, 2016) is 32.22 inches, or 153% of the long-term year-to-date average
of 21.00 inches.
CARMEL RIVER
LAGOON: During August the
lagoon mouth remained closed and the water surface elevation (WSE) held steady at
approximately 9.0 feet above mean-sea-level (see graph below).
Water-quality profiles
were conducted at five lagoon sites on August 25 when the mouth was closed.
Conditions for steelhead varied with depth but were generally “fair” above two
meters with salinity <1.0 ppt, dissolved
oxygen (DO) levels 4 - 10 mg/l, and water temperatures ranging from 65 - 69
degrees Fahrenheit.
SUMMER STEELHEAD RESCUES: No additional fish rescues were needed in August. Through the end of August, a total
of 5,496 fish had been rescued in the tributaries (5,436 YOY, 32 1+ year
olds, and 28 morts).
FALL SURVEYS: Staff
completed annual embeddedness/substrate size surveys at 13 sites (from Highway
1 to Los Padres Dam) and began planning for the September/October juvenile
steelhead population surveys. MPWMD staff will be working closely with National
Marine Fisheries Service (NMFS) staff this year to collect data from additional
river sites (up to 30 total) as well as conducting fish tagging activities.
