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 May 2016. During the months of
May through October, staff will take bi-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 bi-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 2015 QUARTERLY REPORT:
1.
Carmel
River Clean Up: District staff
removed plastic bags, metal, tires, and trash from long reaches of the Carmel
River starting at Esquiline Bridge and extending downstream to the Highway One
Bridge.
2.
French
Broom (Genista) Eradication in District Restoration Projects: District staff
(Mark Bekker and Matt Lyons) have been removing French broom
from the riparian corridor along the Carmel River in the mid-valley
area. French broom, which is a rapidly
growing invasive weed that often reaches 10 feet tall and occasionally higher, competes
with native plants and can become problematic if left unchecked.
3.
Public
Outreach and Education: On February
16, 2016, District staff gave a presentation on the Monterey Peninsula Water
Resource System and Carmel River Lagoon Dynamics to seniors of Environmental
Science classes from Robert Louis Stevenson School. Then on March 18, 2016,
District staff presented information on the Monterey Peninsula Water Resource
System and Mitigation Program to fifth graders of the International School of
Monterey. On April 2, 2016, District
staff gave a presentation to the Pacific Grove Museum of Natural History
California Naturalist program about the District, which also included a site
visit to the Los Padres Dam.
4.
State
Proposition 1 Integrated Regional Water Management (IRWM) Grant Program: Staff is proposing several actions to
continue implementation of IRWM planning in the region (see related Action Item
in this Board packet).
5.
Sleepy Hollow Steelhead Rearing Facility Intake
Upgrade: Tetra Tech, Inc. completed a
Basis of Design and a draft Initial Study for the project.
6.
Instream Flow Incremental Method Study: The District extended the agreement with Normandeau
Environmental Consultants to update instream flow requirements for the Carmel
River. In addition to a project
description, basic Normandeau will conduct a test in the Carmel River to
determine if habitat suitability
criteria from the Big Sur River can be used for the Carmel River and
conduct streamflow measurements for input to a hydraulic model for the river.
7.
Los Padres Dam Long-Term Plan: The District
received proposals for completion of a volitional upstream passage study at the
dam (see related Consent Calendar item in this packet).
