11.5.2 Project Considerations Similar to Project No. 17 (page 11-84) project considerations for this project involve the likelihood of an uncontrolled release from Harvey Place Reservoir. The 1997 flood event created operational problems for the District that required a variance from the Lahontan Regional Water Quality Control Board for release of recycled water from Harvey Place Reservoir. Project implementation is a question of the likelihood of catastrophic flood events and the District‟s desire to increase its operational flexibility.

Section 12: Fresh Water Management Projects 12.1 Water Right Management West Fork of the Carson River water rights are the cornerstone of the freshwater irrigation, water quality improvement opportunities, and conjunctive use of resources and infrastructure in Alpine County. The water currently available for the recreational pool of Indian Creek Reservoir is transferred surface water rights from the District owned property in Diamond Valley. These rights are planned to be supplemented with other transferred rights in the future to provide a reliable source of water for the Indian Creek Reservoir fishery. In addition to using agricultural water rights for Indian Creek Reservoir maintenance, the movement of freshwater through the system has great benefits to habitat quality and conveyance efficiency. By using the available storage and conveyance facilities to maximize the needs of multiple users many solutions to management objects can be developed. An assessment and quantification of District owned water rights can be found in Appendix G - Water Rights. There are two freshwater management projects and implementation of each is contingent on the success of the District‟s current Hypolimnetic Oxygenation System project, and the District‟s ability to meet minimum water surface elevations in Indian Creek Reservoir. 12.2 Project No. 19 - Use of Mud Lake Winter Diversion for Indian Creek Reservoir Flushing Flow This project addresses the purpose and need statement: PN-9. Ability to meet Indian Creek Reservoir water quality requirements is impaired and the District needs to meet TMDL requirements for the Indian Creek Reservoir. Project No. 19 would divert winter flows in Indian Creek through Indian Creek Reservoir before reaching Mud Lake Reservoir in Nevada. The flushing flows would be diverted from Indian Creek via the Upper Dressler Ditch. The construction of the Indian Creek Reservoir Hypolimnetic Oxygenation System project intends to help ensure water quality maintenance throughout Indian Creek Reservoir, preventing elevated phosphorus levels from polluting downstream water bodies. While Project No. 19 is a management project, it will require infrastructure improvements to increase flushing flows to Indian Creek Reservoir. The Upper Dressler Ditch conveyance Improvements (Project No. 15, page 11-82) address capacity and reliability issues of flow to Indian Creek Reservoir. This operational change has great promise as a means of improving water quality at the cost of agreement of parties and operation changes. 12.3 Project No. 20 - Storage of Water for Downstream Users This project addresses the purpose and need statement: PN-9. Ability to meet Indian Creek Reservoir water quality requirements is impaired and the District needs to meet TMDL requirements for the Indian Creek Reservoir. In an effort to maintain a higher recreational pool in Indian Creek Reservoir, water from transferred water rights can be stored in Indian Creek Reservoir for later use by downstream South Tahoe Public Utility District Recycled Water Facilities Master Plan - October 2009 Page 12-87
