Eberhard No. 1 dam
Eberhard No. 1
Eberhard No. 1 is a privately owned earth dam located in Big Horn, Wyoming, along the Long Draw river. Built for irrigation purposes, this dam stands at 37 feet in height with a hydraulic height of 32 feet. It has a storage capacity of 211 acre-feet and covers a surface area of 15 acres, serving a drainage area of 280 acres. The dam features an uncontrolled spillway with a width of 150 feet and is equipped with a single valve outlet gate.
Despite its low hazard potential, Eberhard No. 1 is currently rated in poor condition as of the last inspection in May 2020. The dam has a moderate risk assessment rating and is subject to state regulation, inspection, and enforcement. With a history of modifications that are not specified in the data, the dam requires attention to improve its structural integrity and overall safety. The risk management measures for this dam are currently unspecified, highlighting the need for ongoing monitoring and potential upgrades to mitigate any potential hazards.
Water resource and climate enthusiasts interested in Eberhard No. 1 will find this dam's data to be a valuable resource for understanding its current condition and operational details. As a vital component of the irrigation infrastructure in the area, this dam plays a crucial role in water management and agricultural practices along the Long Draw river. With its location in Wyoming's Congressional District 00, Eberhard No. 1 represents a key piece of the region's water resource system, prompting the need for continued monitoring, maintenance, and potential improvements to ensure its long-term reliability and safety.
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 Eberhard No. 1
Where does the data for Eberhard No. 1 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.
