PowerPoints: Carmel River-History, Restoration and Protection and Water Supply Problems and Possible Solutions in the Monterey Peninsula Area

ABSTRACT: At the Carmel Residents Association May Meeting yesterday, Larry Hampson, Water Resources Engineer, Monterey Peninsula Water Management District (MPWMD), and Darby Fuerst, Interim General Manager, MPWMD, presented PowerPoint Presentations entitled Carmel River - History, Restoration, and Protection and Water Supply Problems and Possible Solutions in the Monterey Peninsula Area, respectively. The Mission of the MPWMD, an Area Map and information about Larry Hampson and Darby Fuerst are presented. HIGHLIGHTS of the PowerPoint Presentations are presented.


The Monterey Peninsula, Carmel Bay, and South Monterey Bay Region

CRA May General Meeting:

Highlights of Carmel River - History, Restoration, and Protection, A Presentation to the Carmel Residents Association, October 23, 2008 by Larry Hampson, Water Resources Engineer

Topics include, History, Ecology, Restoration and Protection

Threatened Species Protected in 1996 and 1997
Steelhead and California Red-legged Frog

Court Battles, Citizen Efforts, Better Management Halt Degradation of River
1974 - suit over groundwater extraction in mid-Valley
1976-77 - Carmel River Watch (CREW) established
1983 - 84% yes vote for river restoration program
1984 – MPWMD orders pumping to be shifted downstream
1987 – four complaints filed against Cal- Am with SWRCB
1990 – EIR on water allocation results in expanded Mitigation Program for river
1995 – SWRCB issues WR Order 95-10
1996-97 – listing of steelhead and California red-legged frogs spurs tighter federal controls of activities along the river
2000-2005 Cal-Am surface diversions further curtailed
2008 – Coastal Conservancy sponsors Sand Clemente Dam removal and river re-route
2007-08-09 (?) - SWRCB revisits Order 95- 10

What Are the Threats to Resources of the Carmel River?
Los Padres Reservoir may continue to impound sediment from the upper watershed
Loss of surface storage may result in less flow downstream in the summer
Lack of sediment may destabilize streambanks

Armoring of streambanks is likely to continue after large floods

Diversions in lower river continue to affect vegetation and aquatic habitat

Global warming may cause larger swings in temperature and rainfall

Moving Forward
Significant bond act funding may be available to continue restoration and mitigation efforts

Private and non-profit groups such as the Big Sur Land Trust and the Planning and Conservation League are interested in restoring and maintaining the watershed

San Clemente Dam to be removed by State Coastal Conservancy

New water supplies for the Monterey Peninsula are projected to be completed within eight years - these projects will allow a reduction in diversions from Carmel Valley

River Reroute and Dam Removal Maximize the Public Benefits

Mitigation Program Direct Measures
Seaside basin injection/recovery

Fish rescue, rearing, habitat improvement

Irrigation of Carmel River riparian corridor

Vegetation management/modification and augmentation

Streambank and channel restoration

Highlights of Water Supply Problems and Possible Solutions in the Monterey Peninsula Area, A Presentation to the Carmel Residents Association, October 23, 2008 by Darby Fuerst, Interim General Manager

Distribution of California American Water Production by User Type
Approximately 55% Residential

Physical Limitations on Water Supply
Extreme annual and seasonal variability of streamflow in the Carmel River

Inadequate surface water and groundwater storage capacity in Carmel River Basin

Infrequent, but certain drought events, i.e., consecutive dry or critically-dry inflow years

Threat of seawater intrusion in Carmel River and Seaside Groundwater Basins

Legal Limitations on Water Supply
State Water Resources Control Board Order No. WR 95-10 against California American Water (CAW)

Order 95-10 requires CAW to reduce its diversions from the Carmel River by approximately 75%

Water Supply Requirements
MPWMD has estimated that 12,500 acre-feet per year (AFY) of replacement supplies are required to meet existing water demands and comply with Order 95-10 and the Seaside Decision.

In addition, MPWMD has estimated, based on input from the jurisdictions within the District, that an additional 4,500 AFY of supplies are required to meet future water demands within the District

Water Supply Solutions
CAW’s proposed Coastal Water Project

Water for Monterey County Coalition’s1proposed Regional Water Project

Monterey Regional Water Pollution Control Agency’s proposed Groundwater Replenishment Project

MPWMD/CAW’s Phase 1 Aquifer Storage and Recovery (ASR) Project, in operation.

MPWMD’s proposed Phase 2 ASR Project

MPWMD’s proposed Seawater Desalination Project (“95-10 Project”) in the former Fort Ord area.

Although not much was outlined about the proposed desalination project at Moss Landing, it is known that the costs associated with desalination projects have significantly decreases in recent years. Maybe desalination could be a likely and attractive solution to the Peninsula's water needs now and into the future.
