Next Steps on Los Padres Dam
and Reservoir Long-Term Strategic and Short-Term Tactical Plan |
||||
|
Following discussion of this
item, the committee agreed to bring this issue up again at the next committee
meeting. A
summary of the staff report and committee discussion follows. The
consultant for the District, Shibatani and Associates, recommended a
combination of new off-stream storage along with removal of the Los Padres
Dam as the best alternative. The consultant proposed three off-stream
alternatives: (a) Pine Creek dam with an estimated municipal yield of
7,600 acre-feet per year (AFY), (b) Boronda Creek dam, which would create no
additional flow for municipal demand, and (c) an off-stream reservoir on San
Clemente Creek (5,500 AFY for municipal demand). These alternatives
presumed that current environmental instream flow requirements would need to
be met before diversions to meet municipal demand would occur. District staff
recommended that an Instream Flow Incremental Method analysis be completed to
update instream flow requirements and a new surface-groundwater computer
model be developed so that the impacts of each alternative on steelhead and
water supply to pumpers along the river can be analyzed. Staff noted
that riverflow will need to increase in the winter of 2014-15 so that an IFIM
study can be completed. The
Tactical Plan is one of several studies needed to evaluate alternative
strategies, including removal of the dam and restoration of a natural river.
Staff believes that a regulated river may be preferable to dam removal.
The cost to recover the original capacity of Los Padres Reservoir could be up
to $200 million, including at least $30 million for improved fish
passage. However, the amount of increased supply for the community
(about 850 AFY) would likely not be sufficient to justify such an expense
solely for municipal supply. In order to construct a new lower Los
Padres Dam (i.e., a dam downstream of the existing location with a height lower
than the New Los Padres Dam proposed in 1995), the National Marine Fisheries
Service (NMFS) would need to be convinced of the advantages, as one of the
alternatives they support to solve steelhead passage issues and habitat
degradation is removal of the dam. The Water Management District should
determine under what conditions NMFS would support maintaining or enhancing
the existing Los Padres Dam. The
Pine Creek alternative could require mitigation for inundation of five miles
of steelhead habitat. A dam and reservoir on Boronda Creek may inundate land
owned by one or more wineries, and would require work outside of the District
boundary for installation of the reservoir and a tunnel between the river and
Boronda Creek. Alternatively, a diversion point could be placed at the
existing Los Padres Dam (instead of a diversion and tunnel above the existing
reservoir), but this could be a more expensive solution. Creating surface
storage in the Boronda Creek watershed could be advantageous to wineries
because a one-mile portion of Cachagua Creek that currently dries up each
year would flow in the summer. Comments from the
committee. (A) If an alternative in Cachagua Valley is pursued, it
would be good to meet with winery representatives to explain the project’s
advantages and develop options. (B) Los Padres Dam should be retained
and the reservoir dredged. (C) The community will not support off-stream
storage, so an upgrade of Los Padres Dam must be considered. (D)
Dredging Los Padres Reservoir to the original capacity would yield about 850
AFY of municipal water supply at a cost of approximately $200 million.
Dredging is not likely to be the least costly option for increasing water
supply. (E) Leaving Los Padres Dam in place would require a long-term program
to manage the sediment. (E) After the desalination project is built,
the Water Management District should pursue options to use the remainder of
MPWMD’s water right on the Carmel
River (Permit 20808B) for additional water supply so that the right is not
revoked by the SWRCB. |

Update
on Progress to Obtain Source Water Agreements for Pure Water Monterey Project |
||||
|
Following a report from Stoldt,
the committee requested another update at the next committee meeting. Stoldt reported that progress has
been made towards development of source water agreements. (A) It has been decided that the proposed
water sources could be purified to water quality useable for the growers. (B)
Discussions are ongoing regarding the amount of purified water to be allocated
for use on the Monterey Peninsula and how much would be provided to the
Salinas Valley. (C) It is possible that the County of Monterey will amend its
water rights application to include water from the Tembladero Sough and
reclamation ditch. |

Review
Progress on DeepWater Desal Contingency Water Supply Project |

Stoldt reported that Kennedy
Jenks will review the capital cost.
The project cost analysis should be done within 4 to 5 weeks. |
