Dingwall Ditch Reg. dam
Dingwall Ditch Reg.
The Dingwall Ditch Reg. is a privately owned irrigation structure located in Lamar, Colorado, along the Arkansas River. Built in 1964, this earth dam stands at a height of 23 feet and has a length of 2640 feet, with a storage capacity of 958 acre-feet. The primary purpose of this dam is for irrigation, with additional benefits including flood risk reduction and recreational opportunities.
Despite being classified as having a low hazard potential and fair condition assessment, the Dingwall Ditch Reg. is subject to state regulation, inspection, and enforcement by the Colorado Department of Water Resources. With a maximum discharge capacity of 18,500 cubic feet per second and a surface area of 71 acres, this dam plays a crucial role in managing water resources in the region. The risk assessment for this structure is categorized as high (2), indicating the importance of maintaining its integrity and safety.
Overall, the Dingwall Ditch Reg. serves as a vital component of the water infrastructure in Bent County, Colorado, providing essential irrigation water for agricultural purposes while also contributing to flood control and recreational activities. As a privately owned and state-regulated structure, its maintenance and upkeep are crucial to ensuring the continued reliability and safety of this important water resource in the region.
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.

About Dingwall Ditch Reg.
Where does the data for Dingwall Ditch Reg. 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.
