Divide Lake dam
Divide Lake
Divide Lake, located in Boulder, Wyoming, is a privately-owned reservoir primarily used for irrigation purposes. Constructed in 1954, this rockfill dam stands at a height of 12 feet and has a storage capacity of 1681 acre-feet. Despite its relatively small surface area of 133 acres, it plays a crucial role in water resource management in the region, drawing water from Divide Creek for agricultural needs.
The dam at Divide Lake has a low hazard potential, but its condition assessment has been deemed poor as of October 2019. With an inspection frequency of 5 years, the infrastructure faces moderate risk, although no emergency action plan (EAP) has been prepared yet. The spillway, which is uncontrolled, has a width of 40 feet, ensuring the safe release of excess water. Despite its flaws, Divide Lake remains a key feature in the water infrastructure of Sublette County, Wyoming.
In the realm of water resource and climate management, Divide Lake serves as a valuable case study for assessing the maintenance and risk management of aging dams. Its location in a scenic area with limited drainage area underscores the importance of sustainable water practices. As climate change continues to impact water availability, understanding and addressing the challenges faced by structures like Divide Lake will be essential in ensuring the long-term resilience of water resources in the region.

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 Divide Lake
Where does the data for Divide Lake 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.
