PHYSICAL INFORMATION <br />Grand River Ditch originates in Water Division 5 District 51 and terminates in Water Division 1 <br />District 3 in Larimer County. <br />Grand River Ditch, completed in 1890, was original ly cut by hand, with the excavated material <br />used to form the lower and outside banks. The diversion has been in continuous operation since <br />it first diverted water in 1892. Th e ditch was historically used to provide irrigation water to the <br />eastern slope. <br />Grand River Ditch has two feeder ditches, the North Feeder Ditc h and the South Feeder Ditch. <br />The North Feeder Ditch is 15 miles long, windi ng around the east slope of the Never Summer <br />Mountains. It has 16 headgates along the length of the ditch on the following tributaries: <br />West branch of Baker’s Gulch (aka, Little Baker) <br />Middle fork of Baker’s Gulch (aka, Middle Baker) <br />East fork of Baker’s Gulch (aka, Baker) <br />Opposition Creek <br />Mosquito Creek <br />Lost Creek <br />Roaring Creek <br />Big Dutch Creek <br />Middle Dutch Creek <br />Little Dutch Creek <br />Saw Mill Creek <br />Lulu Creek <br />Bennett Creek <br />Red Mountain <br />Princess Creek <br />Grand River Ditch in Rocky Mountain National Park <br />Broken Foot <br />(horizontal feature half way up mountains) <br />The South Feeder Ditch (a.k.a. Little Grand Rive r Ditch or Specimen Ditch) is two miles long <br />and diverts water from Specimen Creek. The Sout h Feeder Ditch joins the North Feeder Ditch <br />of the Grand River Ditch shortly before it crosses out of the Colorado River Basin. <br />The ditch and feeders were orig inally earth-lined or constr ucted wooden flumes. Various <br />improvements have been made to Grand River D itch and its feeders since the ditch was first <br />constructed. In 1975, significant improvements we re made to the Grand River Ditch system. <br />Along the North Feeder Ditch, 3,600 linear feet of ditch was lined with a membrane lining and <br />760 feet of wooden flume was replaced with steel pipe. Along the South Feeder Ditch, <br />improvements were made to increase capture efficiency, enhance maintenance, and improve the <br />ditch system. Specifics of these modificati ons to the South Feeder Ditch are unknown. <br />Length: <br /> Approximately 15.13 miles (inc luding North Feeder Ditch) <br />GrandRiverDitch.doc 4 of 10 <br />
