AQUATIC HABITAT AND FLOW CONDITIONS: Carmel River flows held steady in September 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 14-15 cfs since August 3.
Mean daily streamflow at the Sleepy Hollow Weir ranged from 18 to
16 cfs (monthly mean 17.3 cfs) resulting in 994 acre-feet (AF) of runoff
(195,600 total AF in Water Year [WY] 2017). Mean daily streamflow at Highway 1
gage ranged from 5.5 to 4.0 cfs (monthly mean 4.7 cfs), resulting in 270
AF of runoff (201,300 total AF in WY 2017).
There were 0.00 inches of rainfall in September 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 152% of the long-term
year-to-date average of 21.14 inches.
CARMEL RIVER
LAGOON: During September
the lagoon mouth remained closed and the water surface elevation (WSE) held
steady at approximately 8.75 feet above mean-sea-level (see graph
below).
Water-quality profiles
were conducted at five lagoon sites on September 19th and 29th when the mouth was
closed. Conditions for steelhead improved slightly since August and were
generally “fair to good” above two meters with salinity <1.0 ppt, dissolved oxygen (DO) levels 5 - 8 mg/l, and water
temperatures ranging from 62 - 66 degrees Fahrenheit.
FALL FISH SURVEYS: Staff completed the annual juvenile steelhead
population surveys on Oct 2. MPWMD staff is also 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.
