AQUATIC HABITAT AND FLOW
CONDITIONS: During June 2006, Carmel
River streamflow conditions were good for juvenile steelhead rearing, and adult
and smolt downstream migration and fair for adult steelhead upstream migration,
with continuous streamflow to the lagoon.
During June 2006, the mean daily streamflow recorded at the District’s Carmel River Sleepy Hollow Weir gaging station averaged 53.5 cubic feet per second (cfs), and ranged from 30 to 81 cfs.
There were 0.00 inches of measurable rainfall in June as recorded by Cal-Am at San Clemente Dam (SCD), compared to the long-term June average of 0.12 inches at this site. The rainfall total for Water Year 2006 to date is 27.62 inches, 131% of the long-term October-May average of 21.12 inches.
CARMEL RIVER LAGOON: The Carmel River Lagoon was
breached in late December 2005 and remained open until mid-January 2006 when
lower river flow was unable to keep the sandbar open. During February 2006, the mouth opened and
closed a number of times and the water surface elevation (WSE) ranged from
approximately 10 feet above sea level, to a critically low 2.0 feet above sea level. Higher than average river flows during April
and May 2006 kept the lagoon mouth open for all but short periods as shown in
the chart below. In May, tidal
fluctuation and waves caused the lagoon WSE to range from a high of
approximately 8.1 feet to an all time recorded low of approximately 1.7 feet as
the river down-cut through the beach sand berm.
On June 16, 2006, a sand berm was constructed across the mouth of the
lagoon by State Parks, Monterey Peninsula Engineering, the Carmel River
Watershed Conservancy and the Carmel River Steelhead Association to try to
raise the WSE of the lagoon for the summer and help the juvenile steelhead
residing there to survive. On June 19,
the District received a telephone call asking for help sandbagging the failing
sand berm. A total of eight District employees
worked in several shifts for two days along side members of the other
groups. As shown in the graph below, the
WSE was raised from approximately three-feet to eight-feet and held relatively
steady above the six-foot level for the next week and a half.

JUVENILE STEELHEAD RESCUES: Staff expects to start fish rescues in mid-July 2006, when river flows drop to ~ 10 cfs at the Highway One Bridge.
SLEEPY HOLLOW STEELHEAD REARING FACILITY (Facility): Staff continued to ready the Facility for the upcoming rearing season. The computer and alarm systems were checked and upgraded, a section of the bird-netting frame that was damaged over the winter was repaired, rocks were removed from around the river intake screen, and approximately 10 young alder trees were planted along the rearing channel to provide shade. In the rearing channel, staff caulked the perimeter of the weir boards and refitted them with a smaller mesh screen to prevent small fish from moving from bay to bay. Lumber and plumbing materials were purchased for the set-up of the new fiberglass rearing troughs that should be arriving in mid-July. The Facility is now up and running and will be ready to receive rescued fish by mid-July.
