Abstract/Description or Keywords | The South East Kelowna Irrigation District (SEKID) began a process to expand storage capacity in Turtle Lake in 1988. However, during the process SEKID chose to implement water saving measures, such as water meters and education, prior to creation of a reservoir. The Demand Management Program (i.e., water meters and education on crop irrigation techniques with farmers) was highly successful, and SEKID identified a ten percent reduction in demand. These savings have now been committed to growth and SEKID's Capital Works Plan anticipates new supply capacity will be required as early as the year 2010 to satisfy future demand projections At this time, SEKID has initiated a process to update previous works that were started to expand the Turtle Reservoir. Figure 2 shows the conceptual site layout for the proposed reservoir expansion, including dams and intake structures. In general, construction of the new reservoir will include construction of two large dams, one saddle dam, and a water intake near the confluence of Sterling Ditch and Hydraulic Creek. Detailed designs of the proposed water diversions and dams are being prepared by Mould Engineering. Water will be mostly diverted from Sterling Creek, but may also be diverted from Hydraulic Creek if required. The water diversion, under Water License 109619 (Appendix A), has been approved for up to 1500 acre-feet per annum into Turtle Reservoir. The proposed water storage at Turtle Reservoir will be used primarily as a backup to supplement existing water supplies. The approximate storage capacity of the proposed reservoir is about 1.02 million cubic metres (m3 ). The three (3) proposed dam structures will be constructed using material taken from two (2) borrow pit locations (Figure 3). The outlet dam (See Figure 2 for location) will be approximately 136 m in length, at an elevation of 1295 m geodetic and a maximum height of approximately 6 m. The cutoff dam (See Figure 2) will be approximately 170 m in length, at an elevation of 1295 m geodetic and a maximum height of approximately 13 m. The proposed saddle dam will be approximately 2 m in height and will have approximately the same elevation as the two main dam structures. |
