<br />Executive Summary
<br />
<br />This study examines the feasibility of various structural and non-structural measures to
<br />rehabilitate the Greeley and Loveland Irrigation System. The study has been prepared in confonnance
<br />with requirements for funding of the Colorado Water Conservation Board (CWCB) and the dam
<br />safety regulations of the Colorado State Engineer's Office (SEO). This study examines the feasibility
<br />of structural and non-structural alternatives to rehabilitate the following listed projects.

<br />8. Greeley and Loveland Irrigation Canal Rehabilitation
<br />9. Big Barnes Ditch Rehabilitation

<br />11. Oklahoma Check Structure
<br />
<br />The recommended alternative for Equalizer Dam and outlet works consists of removing the
<br />existing gate structure at the southeast outlet of Equalizer Reservoir and replacing it with a conere.te .
<br />
<br />gate/spillway structure, as shown in Figure IV -20, In addition to the structure replacement, this.
<br />alternative also requires a 3.8-foot raise of the dam embankment. The new structure would be placed"
<br />in the previous location ofthe original gate structure, The existing gates and gate stnlCture'
<br />configuration would be used with the exception of a 26-foot broad crested weir located on the north'
<br />(left) side of the outlet gates, The structure would be built on a monolithic foundation, which would
<br />
<br />.. -'~'
<br />
<br />serve as the stilling basin forthe weir and the floor for the outlet gate structure. A ,single spa~l:i-> ,
<br />foot wide concrete bridge deck ,with steel handrails, would span the entire structure width of60 'feet:.
