The inlet in Sand Creek is not visible in aerial imagery available through ArcGIS and GoogleEarth. The imagery with the Larimer County Road Department GIS shows a concrete diversion box. There appears to be a road to and a small structure at the site.
The water diverted from Sand Creek also includes water diverted upstream from Deadman Creek by the Deadman Ditch.

The outlet is a free-flowing arroyo. The width of the eroded arroyo appears to be about 77 feet (estimated from aerial imagery).

Diverts water from Deadman Creek and several other smaller unnamed creeks into Sand Creek. Sand Creek is still in the Laramie River basin. Downstream, the Wilson Supply Ditch diverts this water into Sheep Creek, thence to the Poudre River basin.

 Description of irrigation work.
|
|
The original owners of the Windsor Reservoir are constructing a system of ditches in the mountains, about 47 miles west of their reservoir, which will greatly increase the supply available for storage. In 1902 they had completed and used the Sand Creek or Divide Ditch, which is 1½ miles long and has a capacity of 250 cubic feet per second. It cost $1,500. The ditch diverts water from Sand Creek, a tributary of the Laramie River, and carries it over the divide into Sheep Creek, one of the small tributaries of the North Fork of the Cache la Poudre River. In 1901 the flow of Sand Creek at this point was measured and was found to vary between 6 and 240 cubic feet per second, and it is expected to furnish a good supply for storage in the Windsor Reservoir every year. In 1902, however, the Sand Creek Ditch did not at any time carry over 31 cubic feet per second and the total amount supplied by it was 60,700,000 cubic feet, or an amount equal to one-eighth
of the capacity of the Windsor Reservoir. Water was run through the ditch from May 9 to July 10, inclusive, and from July 16 to 23, inclusive.
This supply drawn from the Laramie River will he reinforced by two other ditches, one of which, the Deadman Ditch, has been completed and will be used in 1903. It crosses Deadman Creek, a tributary of the Laramie River, and several other small creeks or draws, catching the flow of all of them and carrying it over the divide to Sand Creek, the water finally being taken by the Sand Creek Ditch. In 1903 the other of these ditches, called the Columbine Ditch, is to be constructed. It is planned to divert the flow of Columbine Creek, a tributary of Sand Creek, and discharge it into the North Fork of the Cache la Poudre River. It is 2½ miles long and the Deadman Ditch is 5 miles long. It is estimated that these two will furnish about the same amount as the Sand Creek Ditch each year. There are no interests on the head waiters of these streams in Colorado, and therefore no objections to these diversions have been made in that State. But Laramie River and Sand Creek flow north into Wyoming, where both arc used for irrigation. This plan of increasing the available amount of water for storage in the reservoirs of the Cache la Poudre Valley at the expense of the irrigation interests in Wyoming has been complained of and a suit is now pending in the United States court.

Water is diverted from the Laramie River just below the West Branch thereof,
and from the Rawah and Lower Supply Ditch which diverts Rawah Creek
and possibly a number of smaller creeks along its route to the south.
I say “possibly” because I am unable to see diversion structures in aerial imagery.

The ditch follows an upward gradient southward from the Pass, intercepting flows from the upper Michigan River and numerous local tributaries. The Ditch and the original Joe Wright Reservoir were constructed by John McNab and William Rist. Construction was done in three stages between 1901 and 1913, to augment water supplies of the Mountain Supply Ditch Company. Following a series of (bankrupted) ownerships, the Ditch became part of the North Poudre Irrigation Company, which owned and operated the ditch until it was acquired by the City of Fort Collins in the early 1970s (Thaemert and Thaemert, 2001)
|

The initial water control structures were built of timber; for reasons of available construction season, access, and material availability. The first stage of construction, with a decree date of July 10, 1902, included the three-mile long reach from Cameron Pass to the middle fork of the Michigan River. The open channel in that reach traversed at least one unstable earthslide area and three areas with steep side slopes that presented continual stabilization difficulties. Under the decree of July 9, 1904, the ditch was extended another mile upstream to intercept left-side tributaries. That reach traversed a quarter-mile long area of bare, steep, unstable slope that provided continual challenges for operation and maintenance--especially when summer thunderstorms would result in debris flows into the channel. The on-going quest for trans-basin water resulted in the (conditional) decree of September 9,1910, which involved extension of the ditch for another two miles to intercept Agnes Creek, directly below Lake Agnes. Unstable hillslopes on that upper two-mile reach resulted in the installation of a two-foot diameter wood stave pipeline in the ditch on the upper half (Thaemert and Thaemert, 2001)

One area of the ditch known as “the mudslide” became unusually unstable in 2014. A geotechnical assessment in 2015 showed that a tunnel that would re-route the aqueduct through the mountain in stable rock was the best solution. A 766 foot long tunnel with a curve on a 630 foot radius was begun in June 2016, and completed at the end of September 2016.

Windy Gap Reservoir is a small diversion facility located directly below the confluence of the Colorado and Fraser rivers, about 5 miles (8.0 km) downstream of Granby. Water from the Fraser River, as well as other inflows to the Colorado below Granby Dam, is diverted here and pumped eastwards to Lake Granby.
The existing 445-acre-foot Windy Gap Reservoir was not built for water storage. Instead, it acts as a forebay to pool the water before it enters the Windy Gap Pump Plant and is pumped to Lake Granby.

Shadow Mountain Lake is an artificial lake created by Shadow Mountain Dam. The lake bed was a relatively flat meadow, which accounts for its shallow depth (37 feet).
The active pool, amount of water that can be drawn down,
is very small because the pool elevation is the same as Grand Lake,
making Shadow Mountain Lake essentially a canal to move diverted water to Grand Lake from the Lake Granby Pumping Plant.

Grand Lake is Colorado's largest and deepest natural lake. It is located in the headwaters of the Colorado River in Grand County, Colorado. The lake fills a glaciated valley that is dammed in part by glacial till from the Pinedale Glaciation, and is younger than about 12,000 years. Natural tributaries to the lake are the North Inlet and East Inlet, both of which flow out of Rocky Mountain National Park, which surrounds the lake on three sides. Grand Lake was named Spirit Lake by the Ute Tribe because they believed the lake's cold waters to be the dwelling place of departed souls.
