2015 – Project Justification – Addressing An Urgent Water Supply Need For A Disadvantaged Community In The Greater Monterey County Irwm Region
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
One hundred percent of Castroville’s water supply comes from the 400-foot aquifer of the Pressure sub-basin of the Salinas Valley Groundwater Basin. Groundwater levels in the aquifer dropped more than 100 feet below the seal level as of July 2015 at static conditions. Water levels dropped to more than 190 feet below the mean sea level during operation of the water well. The dramatic drop combined with the close proximity of the Pacific Ocean (less than 4 miles) and to existing seawater intrusion (less than ¼ mile) raised significant alarm that the existing water supply system to Castroville was imminently …
1999 - Salinas River Watershed Management Action Plan, Central Coast Regional Water Quality Control Board
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
To more effectively protect and improve water resources, the Action Plan attempts to develop local solutions to local problems. Many significant identified water quality impacts in the Salinas River Watershed, such as erosion and sedimentation, nitrates in the groundwater and surface water, and older, discontinued pesticides in sediments and animal tissues, are primarily associated with nonpoint pollution sources. Also, widespread groundwater pumping contributes significantly to seawater intrusion into the coastal aquifers. The Action Plan approach includes: 1. devoting additional Regional Board resources to watershed activities, 2. increasing the Regional Board presence by developing partnerships with landowners, local governments, resource agencies …
1999 - Water Resources And Land Use Change In Salinas Valley, Watershed Institute Report No. Wi-1999-01
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
The 1999 report prepared by Fred Watson, Lars Pierce, Mel Mulitsch, Wendi Newman, Adrian Rocha, Mark Fain and Jodiah Nelson of the Watershed Institute, describes the progress made toward the use of computer modeling to provide both understanding and predictive capability. The Salinas River watershed of over 11,000 square kilometers supports large areas of intensive agriculture production, including large areas of intensive crop production, and extensive cattle ranches supporting annual grasslands. Mainly a dry climate with limited surface water resources, the valley has a finite groundwater system. Agriculture accounts for 93.5% of the groundwater extractions that exceed recharge by 40,000-50,000 …
2015, Aug. 20 - Groundwater Recharge On East Side Soils Of The Salinas Valley
2015, Aug. 20 - Groundwater Recharge On East Side Soils Of The Salinas Valley
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
Discussion of the historically low groundwater levels in the Salinas Valley, noting that the shallower wells have become unreliable. As the groundwater levels drop below sea level, the seawater intrusion in the coastal aquifers will worsen. Because of the fast-declining groundwater levels on the east side of the Salinas Valley, the potential for seawater moving inland increases. Enhancing recharge in these areas would be beneficial in reducing seawater intrusion while lowering flood risk and erosion damage. The article reviews potential strategies to increase infiltration of rainwater during winter storms thereby recharging the underlying aquifer.
2013-2014, August - Integrated Regional Water Management Plan For The Greater Monterey County Region
2013-2014, August - Integrated Regional Water Management Plan For The Greater Monterey County Region
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
An Integrated Regional Water Management Plan (IRWM Plan) developed by 18 member entities that include government agencies, nonprofit organizations, educational organizations, water service districts, private water companies, and organizations representing agricultural, environmental, and community interests. The IRWM Plan is an expansion and modification of a previous plan – the May 2006 Salinas Valley Integrated Regional Water Management Functionally Equivalent Plan developed by Monterey County Water Resources Agency. While the traditional approach to water resource management has typically involved separate and distinct agencies managing different aspects of the water system, i.e., water supply, water quality, flood management, and natural resources, integrated …
