The HID service area consists of 32,745 acres of irrigated farm land in Weld County. The service
area starts about 2 miles west of Hudson and extends generally east and south along 1-76, to about
9 miles east of Keenesburg. The irrigated acreage within the service area is primarily used to grow
corn, beans, sugar beets, wheat, barley, sunflowers, alfalfa and grass hay. The HID is a taxing
district that levies a tax per acre based on benefits received, not an ad valorem property tax. Each
HID acre is entitled to a pro-rata share or allocation of the water available under HID's water rights.
The HID's direct flow water is diverted at the Burlington Canal Headworks and continues 16 miles to
and past Barr Lake. It then continues 25 miles in the Denver Hudson Canal to Horse Creek
Reservoir, and from there continues another 25 miles to Prospect Reservoir, The HID is divided
into 3 Divisions. The HID delivers water available from 123 shares of Burlington Barr stock and 560
acres of FRICO Barr Division to 3,075 acres in Division I. From Horse Creek Reservoir, the Denver
Hudson Canal supplies irrigation water to 7 laterals and Lord Reservoir, providing water to 20,460
acres in Division II. From Prospect Reservoir, the Prospect Lateral supplies irrigation water to two
laterals and Olds Reservoir delivering irrigation water to 9,210 acres. Average annual HID
diversions are 39,950 AF and delivery is 19,175 AF.
