Ek Addition No. 1 Dam dam
Ek Addition No. 1 Dam
Ek Addition No. 1 Dam, located in Natrona County, Wyoming, serves as a crucial structure for debris control along Ek Creek. Built in 1966 by the Bureau of Land Management, this gravity dam stands at a hydraulic height of 24 feet and a structural height of 29 feet, with a length of 790 feet. With a storage capacity of 103.3 acre-feet, it primarily functions to mitigate potential hazards from debris and has a low hazard potential rating.
Despite its importance, Ek Addition No. 1 Dam is currently assessed to be in poor condition, highlighting the need for maintenance and potential improvements to ensure its long-term effectiveness. The dam's last inspection in July 2017 revealed its deteriorating state, prompting concerns about its structural integrity and overall stability. With a moderate risk assessment rating, there is a pressing need for proactive risk management measures to address any potential vulnerabilities and enhance the dam's resilience to climate-related challenges.
As water resource and climate enthusiasts closely monitor the state of Ek Addition No. 1 Dam, its critical role in debris control along Ek Creek underscores the importance of ongoing maintenance and risk mitigation efforts. With the dam owned, funded, and overseen by the Bureau of Land Management, collaboration and strategic interventions are essential to safeguarding this essential infrastructure asset and ensuring its continued functionality in the face of evolving environmental conditions.

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 Ek Addition No. 1 Dam
Where does the data for Ek Addition No. 1 Dam 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.
