C. Study Area and Existing Facilities Description South Side Dam is a small, Class II embankment dam located in Larimer County near Loveland, Colorado, 40022'06" north latitude and 105006'34" west longitude. The dam is farther described as being just upstream of Ryan Gulch Reservoir in Section 27, Township 5 North, Range 69, west of the 6th principal meridian. It is owned and operated by the South Side Reservoir Company. The SEO identification number for South Side Reservoir is DAMID # 040213 in Water Division #1. The dam consists of an earthen embankment approximately 30-foot in height. The dam crest is approximately 600-feet long and also serves as a county road with an elevation of 5045.6 (gage height 30.5). The spillway, located beyond the left abutment of the dam, consists of a concrete control structure just downstream of a 5-foot road cut with an elevation of 5040.6 (gage height 25.5) and well-grassed sheet flow chute bordered by natural rock outcroppings. Natural rock outcroppings serve to effectively separate spillway flows from any proximity of the dam. .A 16" diameter steel outlet pipe with a "center of the dam" gate chamber is part of the original construction of the dam. The outlet was previously modified to include the replacement of 20-foot sections on either end of the outlet with 15" PVC pipe. The gate structure is in need of replacement and the county road interferes with the existence and operation of the gate chamber. The county road was apparently an afterthought to the construction of the dam. The advent and presence of modern day vehicles in close proximity to the pre-exiting concrete gate chamber has created a hazard to the South Side structure and operations personnel as well as to the traveling public. D. Water Demands The scope of this project includes the rehabilitation of the existing outlet works and resolution of the spillway issues. No additional water supplies, above or beyond that which has not been legally decreed and historically used, will be developed in connection with this project. No new or increased diversions will be made and no additional storage capacities will be created. The use of the water will not change 15
