AQUATIC HABITAT AND FLOW CONDITIONS: During October, a couple of small rain events
increased base flows to the Carmel River. This caused the river to start
rewetting approximately 2 miles of intermittent and dry area. The mainstem river is still intermittent from
the Palo Corona reach to just below the Rancho San Carlos area. The lagoon
mouth was closed for the entire month (see graphic below). Rearing conditions were adequate in the upper river
and are improving in the lower river. Los Padres Reservoir stopped spilling on
June 13, 2025 and we began using storage to meet flow
requirements. The water surface
elevation at the end of the month was 1015.53 feet. Flow out of the reservoir
at the end of the month was 5.1 cfs.
October’s streamflow at the Sleepy Hollow Weir gaging station ranged from 4.1 to 7.0 cfs (mean 5.45
cfs), while flows at the Highway 1 gage ranged from 0.9 to 0 cfs
(mean 0.04 cfs).
There was 1.11 inches of measurable rainfall in October
as recorded at the San Clemente gauge. The total rainfall for Water Year
(WY) 2026 (which started October 1, 2025) is 1.11 inches., which is 150%
of normal to date.
FISH RESCUE: On May 16, 2025, District staff started fish rescues due to
drying conditions in the tributaries. On
June 27, 2025, staff started conducting fish rescues in the mainstem Carmel
River, impacted areas include the Crossroads area to the Shulte Bridge area, as
well as the Trail and Saddle club area, for a total of approximately 5 miles.
As of the end of October, a total of 7,470 fish have been rescued (6,475 YOY, 968 1+ year olds, 3 adult kelt
and 24 mortalities). Fish are being released and tagged this season in a
variety of locations in order to track which produces
the best return rates (part of the Rescue and Rearing Management Plan’s release
strategy). These release areas are the
lagoon, perineal waters of the mainstem and the Sleepy Hollow Steelhead Rearing
Facility.
CARMEL RIVER LAGOON: In October, the lagoon’s Water Surface Elevation
(WSE) ranged from approximately 6.6 to 9.0 feet (NGVD 1988) (see graph below). Water
quality depth-profiles were conducted at five sites on October 28, 2025, while
the lagoon mouth was closed, water surface elevation was 8.75 feet at the time
of sampling, and river inflow was approximately 0 cfs. The north arm of the lagoon was disconnected
from the main lagoon with intermittent pools.
Lagoon stratification was observed at about 0.5 meters depth at all
sites. Salinity levels ranged from 10.5-23.5 parts per thousand (ppt), throughout
the lagoon. Water temperatures ranged
from 57.5-64.7 degrees Fahrenheit, and dissolved oxygen (DO) levels ranged from
1.31-19.1 mg/l.
