Project Presentations for IRWM Funded Projects

  • Westside Pond Dam Rehabilitation Project Description:  Once rehabilitated, the dam will allow the pond to hold approximately 120 acre feet of water. This will be beneficial in numerous ways, including:  1.  Emergency Response – Dedicated water supply for fire suppression efforts 2.   Ecosystem / Habitat Restoration – Approximately 45 acres of freshwater and riparian habitat can be re-established. Critically important native species, including plants, waterfowl, amphibians, mammals, and fish, can be re-established 3. Ground Water Recharge – the impoundment of water is expected to enhance groundwater and provide for additional water supply stability to both tribal and private wells in the area 4.  Flood Control Benefits – the retrofitted dam and increased storage capacity of the pond will be better equipped to handle changing rainfull run-off patterns and maintain flood protection without reducing local emergency water storage.
  • THS Presentation and Twain Harte Storm Drain Rehabilitation Project Description:  This project includes stormwater improvements to Twain Harte Elementary School to include the following: Install a minimum of 12 rainwater collection tanks with a combined minimum storage capacity of 63,000 gallons to capture runoff from rooftops for irrigation and existing garden, construct a minimum of 2,500 feet of bioswales, and install a minimum of 9,600 square feet of drought tolerant landscaping.
  • GCSD Lift Station 16 Project #27  Project Description:  The design of this lift station reconstruction mirrored, in many ways, existing lift station designs  in other portions of the District, to keep reconstruction design costs down. This resulted in simplified construction drawings and specifications for use in bidding of this reconstruction work.  This project provides a reconstructed lift station for the Big Oak Flat Community (Disadvantaged Community) that is reliable and will serve the needs of the community for many years to come.  The beneficiaries of this project are: GCSD; the entire Big Oak Flat Community (which is a Disadvantaged Community based on median household income); recreational uses at Don Pedro Reservoir and the Tuolumne River, drinking/irrigation water, and the flora and fauna that live along the Rattlesnake Creek.
  • MSD Wastewater Improvement Project #2   Project Description:  The Project is located in the community of Murphys, in Calaveras County. The Project has constructed new sprayfield infrastructure on 20 acres adjacent to the existing wastewater treatment facility (WWTF) to provide reliable effluent disposal capacity under various climatic conditions, specifically heavy precipitation years. The Project will reduce non-point source contamination of ground and surface water and protect public health and the environment from potential effluent bypass or spills resulting from inadequate disposal capacity.                      
  • TRT Watersheds and Efficiency #22  Project Description:  The Regional Watershed Conservation Program is a multi-faceted project intended to promote and implement water conservation activities, water use efficiency and improvements, water demand/control methods and alternative water source development programs in the Tuolumne-Stanislaus IRWM region. This program takes place under the leadership of the Tuolumne County Resource Conservation District, with the assistance of the Sierra Watershed Progressive and the Tuolumne River Trust.                                                                                                                      
  • TUD Phoenix Lake Project #18   Project Description:  Implementation of the plan provides 139 acre-feet of restored capacity to Phoenix Lake, reduction of erosion and sediment deposition into Phoenix Lake and in the various watersheds, improved water quality, and improved habitat for fish and wildlife.  The beneficiaries of the project are customers of TUD, both domestic and agricultural users, the environment, the Sullivan Creek, Tuolumne River, and Delta watersheds.  The cost of treating water in Phoenix Lake is reduced by improved water quality. These cost savings are passed on to the customers in the disadvantaged communities via their water rates. Restored storage capacity also increases the District’s ability to provide water supply for longer durations during emergencies.
  • TCRCD – Small Landowner Grant-#16  Project Description:  The primary goal of this project is to reduce nonpoint source (NPS) pollution in the Stanislaus and Tuolumne River watersheds. This will be accomplished by engaging a portion of the community, small acreage landowners with significant potential to adversely impact water quality throughout these two watersheds. This community is outside of the traditional support network for agriculture and therefore will benefit from targeted education and outreach.
  •  ATCAA – In-Home Water Conservation-DAC-#17   Project Description:  The objective of this project is to stabilize or reduce the money a given home or business must spend on water by identifying and installing water conservation measures in their home or business.  ATCAA already has  crews, shops, vehicles and tools in addition to an outreach/intake staff.   Disadvantaged Community individuals and businesses are eligible for onsight conservation improvements and education.  As part of the metrics, ATCAA will include the number of homes and businesses worked, the measures installed and the savings expressed in both dollars and gallons saved.
  • CCWD-Douglas Flat-Vallecito-#25  Project Description:  The objective of the project is to increase the storage capacity of the ponds to allow for utilization of the entire design capacity of the treatment facility. The treatment plant produces high quality tertiary treated water which can be used for recycling. Increasing the capacity of the flow would also improve ground water quality since there would be no need for septic tanks.  The design phase includes development of plans and specifications for the construction of the new 86 acre feet storage pond.  The new storage pond will ensure all existing infill and existing septic facilities will be able to tie into the facility. This will have a positive impact on the groundwater in the area.
  •  TCRCD Conservation Outreach-#35 Project Description:  This project provides a suite of program elements that  promote high‐efficiency
    technologies and best water conservation practices that improve indoor and outdoor water use efficiency throughout the Upper Tuolumne and Stanislaus watersheds, and provide cash rebates to residents and businesses that implement various water saving practices including installation of rain barrels, rain gardens, high efficiency toilets, urinals and washers, and laundry to landscape irrigation.
  • *THCSD Water Supply Reliability Wells #38 Project Description:  The Meadow Lane Groundwater Well Project consists of drilling a new groundwater well on an existing District parcel to supplement the District’s only water supply. The overall project will enable the District to access and treat an estimated 100 gallons per minute of groundwater for distribution to its customers. This alternate supply would account for approximately 80% of  normal winter water demands and 36% of normal summer demands, providing drought and emergency reliability now and in the future.
  • USFS – Upper SF Stanislaus River Watershed Project-#9 Project Description:   The Stanislaus National Forest is restoring at-risk meadows in the upper watershed of the South Fork Stanislaus River. By repairing and stabilizing headcuts, filling gullies, re-designing stream channels, rerouting trails, and improving nearby roads, the hydrologic function of these meadows will be maintained and improved. The resulting benefits include increased subsurface water storage, flood attenuation, improved water quality, carbon storage, and habitat for sensitive species.
