About this dam

Eastdale Creek Detention No.1

Located in Casper, Wyoming, Eastdale Creek Detention No.1 is a crucial water management structure designed for flood risk reduction along the Holman Draw river. This earth dam, standing at 24 feet high with a hydraulic height of 19 feet, was completed in 2008 and serves a primary purpose of flood risk reduction. With a storage capacity of 57 acre-feet and a drainage area of 1.89 square miles, the dam plays a vital role in protecting the surrounding areas from potential flooding events.

Despite its low hazard potential and fair condition assessment, Eastdale Creek Detention No.1 is regularly inspected by the state regulatory agency to ensure its structural integrity and operational effectiveness. The dam features an uncontrolled spillway and has a maximum discharge capacity of 437 cubic feet per second. With its stone core and soil foundation, the dam covers a surface area of 5 acres and provides essential flood protection for the local community, showcasing the importance of sustainable water resource management in mitigating climate-related risks.

Maintaining a moderate risk rating, Eastdale Creek Detention No.1 continues to be a critical infrastructure asset in the region, overseen by local government authorities and adhering to state permitting and inspection requirements. With its strategic location and design, this detention structure serves as a testament to the ongoing efforts to safeguard water resources and combat the impacts of climate change in Wyoming's Natrona County.

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 Eastdale Creek Detention No.1

Where does the data for Eastdale Creek Detention 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.
