About this dam

Enl

Enl, T55nr75w17swnw is a private earth dam located in Campbell, Wyoming, along the Roundup Draw river. Built in 2008 by designer Hugh Lowham, this dam serves multiple purposes including irrigation, fire protection, stock watering, and small fish pond activities. With a height of 17 feet and a hydraulic height of 12 feet, it has a storage capacity of 439 acre-feet, with a normal storage level of 232 acre-feet.

Despite its low hazard potential, Enl, T55nr75w17swnw is currently rated in poor condition, with a condition assessment conducted in June 2014. The last inspection was in July 2019, with a recommended inspection frequency of 5 years. The dam features an uncontrolled spillway with a width of 80 feet and an outlet valve. In case of emergencies, the dam lacks an Emergency Action Plan (EAP) and has not been assessed for its compliance with guidelines or the preparation of inundation maps.

Overall, Enl, T55nr75w17swnw presents a moderate risk level (3) due to its poor condition assessment and lack of emergency preparedness measures. As a focal point for irrigation and other water resource activities in the region, it is essential for the dam's owners to prioritize maintenance and safety measures to mitigate potential risks and ensure the continued sustainability of its functions for the local community.

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.

FAQ

About Enl

Where does the data for Enl 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.
