MONITORING
OF RIPARIAN VEGETATION: During the winter season, the District
suspended the riparian vegetation monitoring program. The monitoring of soil moisture, groundwater
levels, and canopy defoliation (a measure of vegetation moisture stress) will
resume in June 2020. During the months
of June through October, staff will take monthly measurements of depth to
groundwater and canopy vigor in areas where willow and cottonwood trees may be
impacted by lowered water levels caused by groundwater extraction. The areas monitored are in the vicinity of
California American Water’s (Cal-Am) Cañada and San Carlos wells, and the
District’s Valley Hills (next to Cal-Am’s Cypress Well) and Schulte (next to
Cal-Am’s Schulte Well) Restoration Projects.
The District’s monitoring provides insight into the status of soil
moisture through the riparian corridor by collecting and analyzing monthly
readings from the District’s array of monitoring wells and pumping records for
large-capacity Carmel Valley wells in the Cal-Am system.
OTHER
TASKS PERFORMED SINCE THE JANUARY 2020 QUARTERLY REPORT:
1.
Carmel
River Basin Hydrologic Model: District
staff continue to work on the Carmel River Basin Hydrologic Model. Multiple
presentations have been given to National Marine Fisheries Service and
California Department of Fish and Wildlife to help them understand model
performance and how it could be used for specific water supply scenarios. Work
is currently underway to run various model scenarios with regards to Los Padres
Reservoir alternatives.
2. Sleepy
Hollow Intake Retrofit: District staff
have been testing various pumps and equipment at the Sleepy Hollow Steelhead
Rearing Facility. All of this work is being done to
get the facility ready for the fish rescue season that is expected to start in June.
In addition, netting has been set up over the rearing channel to help prevent
predation of young of the rear steelhead that will be placed there this summer.
3. Steelhead Permit Reporting
Requirements:
The District has been uploading steelhead rescue data from last years steelhead
rescue season to state and federal databases. This reporting is required to
keep the District’s Scientific Collecting Permits valid as well as help
regulators understand the current state of steelhead on the Carmel River.
