Emergency Loan Application and Feasibility Study <br />Consolidated Home Supply Ditch and Reservoir Company[BORROWER] <br />Project Background <br />During the unprecedented flood of September 2013 in the tributaries to the South Platte River, a <br />significant number of diversion structures and dams along the river corridor were damaged. The <br />Project repair/rehabilitation proposed in this Feasibility Study received significant damage as a <br />result of the flood. <br />The Big Dam on the Big Thompson River is a 65-foot high masonry arch dam built in 1895. It is <br />not a jurisdictional dam as the reservoir is filled with alluvium and only a few acre-feet of water <br />is stored. The structure serves as a point of diversion for the Consolidated Home Supply Ditch <br />and Reservoir Company. It also serves as point of diversion for the City of Loveland. <br />During the flooding, the top five feet of the masonry structure was washed out. In addition, the <br />left abutment contact, and mortar between masonry blocks was partially lost. <br />Water Rights <br />The water rights impacted by this project include: Refer to Exhibit I attached <br />Name Water <br />Court Case <br />Appropriation <br />Date <br />Adjudication <br />Date <br />Amount <br />(cfs or AF) <br />Avg. Annual <br />Yield (AF) <br />Project Description <br />The goal of the project is to restore the condition of the dam to pre-flood conditions or <br />better.

The project already serves <br />multiple users. Consolidated Home Supply Ditch and Reservoir Company and the City of <br />Loveland. <br />Selected Alternative 3 - [Reconstruct the Dam to Pre-Existing Flood Conditions]: The selected <br />alternative is to reconstruct the dam crest to pre-existing flood conditions utilizing masonry and <br />concrete. The erosion holes will be repaired with shotcrete. The abutment buttress will be <br />reconstructed with concrete, shotcrete, anchor bars, and grout. The masonry will be repointed <br />with mortar. Please see the attached repair report.
