  • 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.

  • Forever Green Water Conservation Patch
    California is in the middle of a very serious drought and it is up to us, as stewards of our land, to make every effort to conserve water and help educate others to do the same! This patch program has been designed to educate the participants about water conservation, exploring your water footprint, how water is treated, water runoff, and to save money reducing unnecessary water usage. You will explore and investigate your local water district through printed materials and links found within this patch program. Learn how to test your local water source and compare results. Visit locally suggested water sources, water bodies, creeks, and beaches to gain a better understanding of your watershed. With guided instructions you’ll learn how to reach out to communities and help spread the word about water conservation. By reducing wasteful water practices you’ll save money on your water bill. Within this patch program, you’ll learn which county has a water rebate program for customers being proactive about water conservation. 1. Get to know your H2O! 1.
