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. |

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. |
