IRRIGATION
OF RIPARIAN VEGETATION: Supplemental
watering of riparian restoration plantings occurred January through March 2013
because of low rainfall. Three Monterey Peninsula Water Management District
(District) riparian habitat restoration sites (DeDampierre, Trail and Saddle
Club, and Red Rock) all needed supplemental irrigation to help establish young
seedlings.

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 2013.
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 2013 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 an
invasive weed (French broom, or genista) from the riparian
corridor along the Carmel River from the Village area to Rancho San Carlos Road Bridge. French
broom competes with native plants and can become problematic if left unchecked.
3.
Public
Outreach and Education: On March 7, 2013,
District staff presented information on the Monterey Peninsula Water Resource
System and Mitigation Program to fifth graders of the International School of
Monterey. Then on March 26, 2013, 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.
4.
State Proposition
84 Integrated Regional Water Management (IRWM) Grant Program: Several chapters of the draft update to the
IRWM Plan have been posted for comment to the IRWM website. During the first quarter of 2013, staff
developed a website site application for project sponsors to upload and
evaluate project applications for inclusion in the IRWM Plan. Stakeholder meetings were held to allow input
on the project review process (February 6) and on objectives and goals for the
Ord Community (February 7). In addition
to the IRWM Plan update, all nine of the other grant-funded planning projects
have commenced work. More detailed
quarterly reports about these projects and the IRWM Plan update can be viewed
at www.mpirwm.org
5.
Sleepy Hollow Ford Removal and Bridge Replacement
Project: The California Department of
Fish and Wildlife approved an amendment to the grant agreement for this project
that will allow the final design and report to be completed in the 2nd
quarter of 2013. However, construction
of the project will be delayed until the San Clemente Dam Removal and Carmel
River Reroute Project is completed.
Construction for the dam removal is expected to begin in June 2013 and the
project should be completed in 2015.
6.
Schulte Road Bridge Replacement: Monterey County Public Works Department re-initiated
bridge replacement construction at this site.
The bridge is expected to be completed and in service before the next
rainy season begins.
7.
Carmel River Lagoon Ecosystem Protective Barrier and
Scenic Road Protection: District staff
attended a public meeting on March 25 to announce proposed alternatives for
installing a barrier on the north side of the lagoon and protection along
Scenic Road. The feasibility analysis if
partly funded through the IRWM grant program.
District staff have also provided technical
support to Monterey County and their consultants on the project.
