摘要

In the 2040 Strategic Water Supply Plan (City of Norman 2001), the City of Norman examined more than 17 possible water supply alternatives for meeting the needs of the city through 2040. Through a rigorous evaluation process based on economics, cost-benefits, environmental impacts and public acceptance, the City determined that the best methods and sources for future water would be, one, expanding the use of well fields and, two, making use of additional raw water in Lake Thunderbird that could be obtained from Oklahoma City and delivered by COMCD through the existing supply system serving Norman, Del City, and Midwest City. The well fields are already under development. The proposed project has been developed to address the other water supply option. Based on the need for COMCD to augment its water supply by up to 4,600 acre-feet per year during times of severe drought, COMCD developed the Lake Thunderbird Critical Need Water Supply Project, which is evaluated in this EA. The intent of this project is for COMCD to enter into an agreement with Oklahoma City to enable the purchase of augmentation water during severe drought periods. The water would be conveyed from the nearby Oklahoma City-owned Atoka Pipeline that presently conveys raw water from Lake Atoka to Stanley Draper Lake. To achieve this, COMCD would connect to the Atoka Pipeline and convey raw augmentation water to Lake Thunderbird via either a buried pipeline or a combination of buried pipeline and natural surface drainage channel. The augmentation water is expected to naturally mix with Lake Thunderbird water, and the mixed water would then be conveyed through the existing raw water delivery system to the member cities.
