Colorado Colony Ditch Co. No. 2 dam
Colorado Colony Ditch Co. No. 2
Colorado Colony Ditch Co. No. 2, also known as Granger, is a private water resource infrastructure located in Big Horn, Wyoming. This irrigation system was designed by SCS and completed in 1957, serving the primary purpose of irrigation along the Peralto Ditch. The dam type is earth with stone core and soil foundations, standing at a height of 16 feet and a length of 165 feet, with a storage capacity of 254 acre-feet.
With low hazard potential and fair condition assessment, Colorado Colony Ditch Co. No. 2 is regulated by the State of Wyoming, with inspection, permitting, and enforcement processes in place by the State Engineer's Office. The dam has a spillway width of 25 feet and is equipped with a slide (sluice gate) outlet gate. While the risk assessment categorizes the structure as moderate, it continues to provide essential water resources for agricultural use in the region.
Despite being a privately owned water infrastructure, Colorado Colony Ditch Co. No. 2 plays a crucial role in sustaining the local economy and ecosystem by facilitating irrigation along the Peralto Ditch. With its strategic location in Sheridan County, Wyoming, this system reflects the importance of efficient water management and the need for ongoing maintenance and monitoring to ensure its continued functionality and safety for all stakeholders involved.
Dam data reference
Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Colorado Colony Ditch Co. No. 2
Where does the data for Colorado Colony Ditch Co. No. 2 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
