Eshom dam
Eshom
Eshom, a privately owned irrigation dam located in Platte County, Wyoming, serves as a crucial water resource along Cooney Creek. Completed in 1947, this earth dam stands at 28 feet high and spans 1192 feet in length, with a storage capacity of 253 acre-feet. Despite its low hazard potential, Eshom is in poor condition as of the last inspection in September 2018, signaling a need for maintenance and improvements to ensure its long-term functionality.
Managed by the Wyoming State Engineer's Office, Eshom is regulated, permitted, inspected, and enforced upon by state authorities, highlighting the importance of compliance with safety and maintenance standards. With a hydraulic height of 23 feet and a spillway width of 100 feet, Eshom has a moderate risk assessment rating due to its poor condition and outdated infrastructure. As climate change continues to impact water resources, the sustainability and resilience of dams like Eshom are crucial in ensuring reliable water supply for irrigation and environmental conservation in the region.
As water resource and climate enthusiasts, it is essential to monitor and advocate for the restoration and modernization of aging infrastructure like Eshom to address the challenges posed by a changing climate. By investing in the maintenance and upgrade of dams like Eshom, we can enhance water security, mitigate risks, and adapt to the evolving climate conditions to safeguard our valuable water resources for future generations.

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 Eshom
Where does the data for Eshom 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.
