Santa Maria Reservoir Company Agenda Item 29b September 13, 2013 (Updated September 26, 2013) Page 3 of 7 Water Rights The Company's decreed water rights include 37,515 AF of storage in Santa Maria Reservoir (1916 priority date), 26,716 AF of storage in Continental Reservoir (1934 priority date), and 275 cfs of direct flow rights from North Clear Creek, Bennett Creek, and Bolder Creek. On average the Company diverts 6,300 AF annually. The CWCB has filed a statement of opposition to the Company's water court application to change the use of certain storage rights in Santa Maria Reservoir. Staff intends to work with the Company's representatives to ensure that the resulting decree contains terms and conditions to prevent injury to any decreed instream flow water rights while allowing the Company's proposal to move forward. Project Description The objective of this Project is to rehabilitate the Continental dam and restore the full storage capacity of the reservoir. Several options were evaluated to address the spillway project including: no action, complete replacement of the spillway, and rehabilitation of the existing spillway. Rehabilitating the existing spillway was selected as it had the lowest cost while still safely passing the required design flood. Several options were also evaluated to address the seepage from the embankment. These alternatives included grouting the left abutment, grouting the dam embankment, and constructing an internal seepage collection system along the downstream dam face. Because of unknowns with grouting, the Company selected the internal seepage collection system as the preferred alternative. Final engineering documents have been prepared and were used for estimating the total project cost.
