Dedicated people spent countless hours discussing concerns, issues and potential solutions to problems. This dedication leads to the production of documents that hope to articulate the outcome of the dialog in a way that is useful for the community. The executive summary identifies the Nacitone Watersheds Management process and products, and attempts to capture the major core findings arising out of both efforts. The Vision The Nacimiento/San Antonio River Watersheds Management Plan should protect water quality and watershed uses for all stakeholders. The Purpose The purpose of the Nacitone Watersheds Management Plan is to identify the existing conditions of and stresses in these watersheds as they relate to water quality, and recommend methods for reducing or eliminating those stressors such as alternative land use practices. The Process The Nacitone Watersheds Management planning process is a stakeholder driven process that represents the interests of residents, agencies and businesses that work and live in the watersheds. The stakeholder process used to produce these products presents an investment of 8800 volunteer hours of time in meetings, field trips, community outreach and planning. The magnitude of the effort includes far more than this if one includes the hundreds of contacts made through flyers, press releases and web-site visits. Each of the products was placed on the web-site for public review. Public comment periods were held for the Goals and Strategies document and the Watershed Management Plan. There were Steering and Technical Advisory Committees as well as a staff team guiding the process and development of the products. The members of each are listed in the acknowledgement section of the plan and referenced in Part 1 “How the Plan was Prepared.” The Products The Nacitone Watersheds Plan was initiated by the Monterey County Water Resources Agency (MCWRA) and funded by a grant from the Regional Water Quality Control Board. As part of the grant, several products were produced to assist the watershed stakeholders in gathering and analyzing existing information about the watersheds to discern critical issues facing the watersheds and potential remedies. These products include: Watershed Resources Inventory (WRI)—Existing watershed information was identified including reports, studies, maps, Geographic Information System (GIS) files, and technical data covering land use, water supply, water quality, ecology, hydrology, habitat and vegetation, agricultural and grazing practices, and planning efforts. The inventory is comprised of a spreadsheet file containing over 300 entries as well as an annotated bibliography of a select number of the entries. 5 Analysis of the WRI (Analysis)— Existing information was compiled in order to establish a baseline describing existing watershed conditions including land use, major water features, water quality, water supply, designated beneficial uses, point and nonpoint sources of water pollution, population, infrastructure, vegetation and habitat, and agricultural and grazing practices. Trends were identified for those items that had sufficient historical data. The Analysis did not include a technical review of compiled information. Grazing Land Management Plan—the Upper Salinas/Las Tablas Resource Conservation District conducted an assessment of the 24,000 acres of grazing land owned and managed by the MCWRA at the Nacimiento and San Antonio Reservoirs to determine impacts on water quality, maintenance of ecological communities, and management of sustainable and restorative grazing. Watershed Goals and Strategies—The WRI and Analysis were utilized by the stakeholder group to articulate goals and planning strategies for future watershed activities that focus on water quality improvements. These include non-regulatory approaches to watershed protection, integration of watershed planning with existing government planning activities, land use planning strategies for watershed protection and potential partnership scenarios which could serve to protect the health of the watershed. In addition, the stakeholders identified research and monitoring opportunities to fill data gaps to address issues of concern, identified many roles and associated responsibilities of stakeholders in implementation of the proposed actions and strategies as well as draft time frames for implementation. Watersheds Management Plan—The Plan is an integration of the above products and includes the geographic boundaries of the watershed, a description of the natural resource conditions within the watershed, a series of goals, objectives and implementation measures for achieving and sustaining water quality improvements, and description of how to monitor, update and maintain the Plan as a living document. The plan is divided into four sections. Part 1 includes purpose and need for the plan and plan preparation. Part 2 is the Existing Conditions section which identifies physical and current conditions

  • Wildland Fire in Ecosystems: Effects of Fire on Fauna
    United States Department of Agriculture Wildland Fire in Forest Service Rocky Mountain Ecosystems Research Station General Technical Report RMRS-GTR-42- volume 1 Effects of Fire on Fauna January 2000 Abstract _____________________________________ Smith, Jane Kapler, ed. 2000. Wildland fire in ecosystems: effects of fire on fauna. Gen. Tech. Rep. RMRS-GTR-42-vol. 1. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 83 p. Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals’ ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire effects on animal communities generally depends on the extent of change in habitat structure and species composition caused by fire. Stand-replacement fires usually cause greater changes in the faunal communities of forests than in those of grasslands. Within forests, stand- replacement fires usually alter the animal community more dramatically than understory fires. Animal species are adapted to survive the pattern of fire frequency, season, size, severity, and uniformity that characterized their habitat in presettlement times. When fire frequency increases or decreases substantially or fire severity changes from presettlement patterns, habitat for many animal species declines. Keywords: fire effects, fire management, fire regime, habitat, succession, wildlife The volumes in “The Rainbow Series” will be published during the year 2000.

  • Monterey County
    Steelhead/rainbow trout resources of Monterey County Salinas River The Salinas River consists of more than 75 stream miles and drains a watershed of about 4,780 square miles. The river flows northwest from headwaters on the north side of Garcia Mountain to its mouth near the town of Marina. A stone and concrete dam is located about 8.5 miles downstream from the Salinas Dam. It is approximately 14 feet high and is considered a total passage barrier (Hill pers. comm.). The dam forming Santa Margarita Lake is located at stream mile 154 and was constructed in 1941. The Salinas Dam is operated under an agreement requiring that a “live stream” be maintained in the Salinas River from the dam continuously to the confluence of the Salinas and Nacimiento rivers. When a “live stream” cannot be maintained, operators are to release the amount of the reservoir inflow. At times, there is insufficient inflow to ensure a “live stream” to the Nacimiento River (Biskner and Gallagher 1995). In addition, two of the three largest tributaries of the Salinas River have large water storage projects. Releases are made from both the San Antonio and Nacimiento reservoirs that contribute to flows in the Salinas River. Operations are described in an appendix to a 2001 EIR: “ During periods when…natural flow in the Salinas River reaches the north end of the valley, releases are cut back to minimum levels to maximize storage. Minimum releases of 25 cfs are required by agreement with CDFG and flows generally range from 25-25[sic] cfs during the minimum release phase of operations.

  • 20020906 Water Issues
    The Californian September 6, 2002 Section: Local Page: 3C Water Issues Divide Residents of Two Counties POLLY KENNEDY SPECIAL TO THE CALIFORNIAN There's a storm brewing in South Monterey County, but this one doesn't contain any water. Actually, a great part of it is about a lack of water. I have learned a couple of valuable lessons over the past decade: don't believe everything you hear, and there are always two sides to every story. These lessons were certainly proven true after a week-long vacation to Oak Shores at Lake Nacimiento with a family from Pacific Grove, which has become somewhat of a summer tradition. We paid for this home probably seven months ago, and it was at the end of July when, much to our chagrin, we heard (they in P.G. and we in King City) that the lake was dried up. I can tell you first-hand this rumor is false. The lake, according to a year-round resident Leslie of Oak Shores, hasn't been dry since the drought of 1990. She told us rumors have been escalating for years, because the lake is - and always has been - an agricultural reservoir and water is let out. The residents of Monterey County, she said, will vote on this issue in November. The lake is filled by rainwater only, and Monterey County uses the water to help keep the saltwater from intruding into the Salinas Valley. Adding to the problem is the lack of rain this past year. A year ago, 16 inches of the precious stuff was measured at Lake Nacimiento.

  • Regional Project Description
    CHAPTER 5 Regional Project Description 5.1 Introduction This introduction discusses the origin of the Monterey Regional Water Supply Program (Regional Project), places the Regional Project in the context of the Coastal Water Project (CWP) as a whole, describes the regional water supplies and needs, and provides an overview of the Phase 1 and Phase 2 Regional Project components. 5.1.1 Project Overview and Background As explained in prior chapters, this environmental impact report (EIR) evaluates the potential environmental effects of a project proposed by California American Water Company (CalAm) to provide a new water supply for the Monterey Peninsula. The project is known as the Coastal Water Project. The water supply is needed to replace existing supplies that are constrained by recent legal decisions affecting the Carmel River and Seaside Groundwater Basin water resources, as described in more detail in Chapter 2. The CWP would produce desalinated water, convey it to the existing CalAm distribution system, and increase the system’s use of storage capacity in the Seaside Groundwater Basin. The CWP would consist of several distinct components: a seawater intake system; a desalination plant; a brine discharge system; product water conveyance pipelines and storage facilities; and an aquifer storage and recovery (ASR) system. Coastal Northern Monterey County has long faced water supply challenges (Figure 3-1 shows the area referred to as Coastal Northern Monterey County). The problems of seawater intrusion and excess diversion have existed for decades. Seawater intrusion was identified in Monterey County in the late 1930s and documented by the State of California in 1946 as part of Bulletin 52.
