H. H. Moore Divide dam
H. H. Moore Divide
H. H. Moore Divide, also known as Coulson Lake, is a privately owned irrigation dam located in Teller County, Colorado. Completed in 1946, this earth dam stands at a height of 30 feet and spans a length of 333 feet. With a maximum storage capacity of 98 acre-feet and a normal storage of 62 acre-feet, this dam serves the primary purpose of irrigation along Rule Creek.
Despite being regulated and inspected by the Colorado Department of Water Resources, the dam's hazard potential is classified as low with a fair condition assessment. However, a high risk level of 2 has been assigned, indicating the need for vigilant risk management measures. With no spillway and a limited emergency action plan in place, the dam poses potential risks that need to be addressed to ensure the safety of the surrounding area and water resources.
Enthusiasts of water resources and climate will find H. H. Moore Divide an intriguing structure due to its historical significance, engineering design, and the potential risks associated with its operation. As stakeholders continue to monitor and manage the dam's condition, it serves as a reminder of the delicate balance between harnessing water for agricultural purposes and ensuring the safety and sustainability of our water resources in a changing climate.
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 H. H. Moore Divide
Where does the data for H. H. Moore Divide 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.
