  • Sweetwater Dam: Then and Now
    Sweetwater Dam: Then and Now By Richard A. Reynolds August 2, 2008 Sweetwater Dam: Then and Now Sweetwater Dam is a very important element of the water supply to the South Bay communities. It is the key to treatment and distribution of local runoff and imported supplies. This year is the 120lh in its long history in this important role. The dam, as you will see in this paper, has withstood many challenges and trials from storms that brought runoff flows from the watershed to the 100-year storm levels. A major storm in 1895, only seven years after completion of the dam, overtopped the dam by nearly two feet. This was proof of the core strength of the gravity arch configuration to withstand hydraulic forces. Sweetwater Dam, when completed in its initial configuration on April 7, 1888 (Figure 1), represented the latest design concept for masonry dams and, at its original completed height of 90 feet, was the tallest masonry, gravity arch dam in the United States. It was completed just in time to quench the thirst of South Bay residents and to ensure their hopes for land speculation, municipal growth and agricultural success. In his Nobel Prize winning novel, "East of Eden", John Steinbeck was describing people in California (albeit, in the Salinas Valley) and their awareness of water conditions in general when he wrote, "And it never failed that during the dry years the people forgot about the rich years, and during the wet years they lost all memory of the dry years. It was always that way." And so it was here in the South Bay.

    Arroyo Toad (Bufo californicus (=microscaphus)) 5-Year Review: Summary and Evaluation Arroyo Toad (Bufo californicus) Photo by permission of Will Flaxington U.S. Fish and Wildlife Service Ventura Fish and Wildlife Office Ventura, California August 2009 5-YEAR REVIEW Arroyo Toad (Bufo californicus (=microscaphus)) I. GENERAL INFORMATION Purpose of 5-Year Reviews: The U.S. Fish and Wildlife Service (Service) is required by section 4(c)(2) of the Endangered Species Act of 1973 (Act) to conduct a status review of each listed species at least once every 5 years. The purpose of a 5-year review is to evaluate whether or not the species’ status has changed since it was listed (or since the most recent 5-year review). Based on the 5-year review, we recommend whether the species should be removed from the list of endangered and threatened species, be changed in status from endangered to threatened, or be changed in status from threatened to endangered. Our original listing of a species as endangered or threatened is based on the existence of threats attributable to one or more of the five threat factors described in section 4(a)(1) of the Act, and we must consider these same five factors in any subsequent consideration of reclassification or delisting of a species. In the 5-year review, we consider the best available scientific and commercial data on the species, and focus on new information available since the species was listed or last reviewed. If we recommend a change in listing status based on the results of the 5-year review, we must propose to do so through a separate rule-making process defined in the Act that includes public review and comment.

  • January 11, 2021 Subject: Request for Qualifications For
    January 11, 2021 Subject: Request for Qualifications for Engineering Design Services Regarding Improvements to Loveland Reservoir’s Boat Ramp and Anchors for Boat Dock and Log Boom SWA File: (Gen) Loveland and Sweetwater Reservoirs – Boat Ramp Improvements To Whom It May Concern: Sweetwater Authority (Authority) is seeking an engineering consultant to provide engineering design services for improvements to Loveland Reservoir’s existing boat ramp and anchors for boat dock and log boom. The Authority encourages participation by local, small and/or disadvantaged businesses. Persons or entities submitting a proposal in response to this Request for Qualifications (RFQ) are referred to herein as “Consultant”, “Proposer”, “Firm”, or “Responder”. A. BACKGROUND INFORMATION Water Transfers from Loveland Reservoir The Authority owns, operates, and manages two surface water reservoirs along the Sweetwater River as key components of its water supply portfolio. Approximately two- thirds of the runoff from the Sweetwater River watershed flows into Loveland Reservoir, located near Alpine, CA, and the remaining one-third flows into Sweetwater Reservoir, located near Spring Valley, CA. Sweetwater Reservoir supplies local surface water to the Authority’s Robert A. Perdue Water Treatment Plant for treatment and distribution to the Authority’s customers. Loveland Reservoir is not connected to the Authority’s distribution system and the only mechanism to transfer water from Loveland Reservoir to Sweetwater Reservoir, so the water is available for treatment, is to open the Bunger valve at the base of Loveland Dam which impounds Loveland Reservoir, to release water into the Sweetwater River channel through the Middle Basin to Sweetwater Reservoir. The reservoirs are separated by approximately 17 miles of Sweetwater River.

  • Covered Species Monitoring
    5.0 COVERED SPECIES MONITORING Preservation of rare plant and animal populations in protected areas is the initial step in achieving long-term conservation. Monitoring efforts are needed to ensure that human-related activities do not present immediate threats to preserved populations nor threaten the ability of a population to persist over time. The covered species monitoring program will identify (1) short-term threats to species persistence and (2) longer-term trends that may suggest declining populations. In either case, active management may be required. The covered species monitoring effort will achieve the plan objectives of documenting the protection of covered species and changes in preserved populations of covered species, collecting new biological data, evaluating the impacts of land uses and construction activities in and adjacent to the preserve, and evaluating management activities and enforcement difficulties in the preserve. This section outlines tasks necessary to conduct the species monitoring program. These include establishing monitoring locations, acquiring appropriately-scaled base maps, establishing permanent plots and monitoring methodologies, and data collection and analysis. It should be noted that not all monitoring parameters can be identified within the context of this plan, because some parameters will be dependent on a detailed assessment of field conditions. Further, it is acknowledged that monitoring data beyond that recommended below would be highly desirable and could provide a more accurate depiction of population viability. Refer to Section 8.0 for additional research studies that should be implemented as funds and/or researchers become available. 5.1 CLIMATIC DATA Both short- and long-term plant and animal population trends can be influenced by climatic parameters such as temperature and rainfall.
