~. ~ <br />Water Project Construction Loan Program - Project Data <br />Borrower: Henrylyn Irrigation District <br />Project Name: Horse Creek & Prospect <br />Reservoirs <br />Drainage Basin: South Platte <br />Total Project Cost: $2,403,000 <br />Type of Borrower: Agricultural <br />CWCB Construction Fund Loan: $2,184,327 <br />(incl. 1 % loan fee) <br />County: Weld <br />Project Type: Reservoir Rehabilitation <br />Water Source: Denver- Hudson Canal <br />Funding Sources: CWCB, H1D <br />Aver. Delivery: 13,850 acre-feet <br />Interest Rate: 2.25% Term: 30 years <br />The HID was formed in 1907 Irrigation District Law of 1905, and consists of 32,745 acres of <br />irrigated farm land in Weld County. The service area starts about 2 miles west of Hudson and <br />extends generally east and south along I-76, to about 9 miles east of Keenesburg. The HID <br />diverts water through the Burlington Canal Headworks on the South Platte River, extending 16 <br />miles to and past Barr Lake. From Barr Lake the Denver-Hudson Canal continues 25 miles to <br />Horse Creek Reservoir, and then continues another 25 miles to Prospect Reservoir. Annual HID <br />delivery is 19,175 AF. Horse Creek Reservoir was constructed in 1910, and is a High Hazard, <br />Class 1 earth fill dam, with a dam height of 64 feet, a length of 4800 lineal feet, and a crest width of <br />16 feet. There is a 200 foot wide earth-lined spillway. The decreed storage right is 19,515 AF, but <br />normal storage is 18,747 acre feet. The outlet works consist of 3 x 48" diameter steel conduits. <br />The proposed project will provide a lining for the outlet works, install additional toe drainage, and <br />resurface and re-grade the dam crest. Prospect Reservoir was constructed in 1914, and is a <br />Significant Hazard, Class 2 earth dam, with a dam height of 43.5 feet, a length of 5,301 lineal feet, <br />and a crest width of 20 feet. There is a 250 wide concrete and riprap spillway. The decreed <br />storage right if for 7,660 AF, but the normal storage is 6,368 acre feet. The outlet works consist of a <br />48" concrete pipe that narrows to about 30" downstream of the control gate, due to previous re- <br />lining projects. The reservoir is currently restricted to 1.5 feet below the historic maximum stage, <br />due to concerns about the stability of the downstream slope of the dam. The proposed project will <br />provide a lining for the outlet works, and resurface and re-grade the dam crest. <br />~ y~'f Koggen ~ ;:2: ~;- <br />~40- ~Firestone ? y g ~ RGAN <br />~~ Z~` Frederick `e~ F~~ x 1, -.
