Eastdale Creek Detention No.2 dam
Eastdale Creek Detention No.2
Eastdale Creek Detention No.2, located in Casper, Wyoming, is a crucial structure designed for flood risk reduction along the Holman Draw. Constructed in 2008, this earth dam stands at a height of 16 feet, with a hydraulic height of 12 feet and a structural height of 19 feet. With a storage capacity of 83 acre-feet and a normal storage of 57 acre-feet, this detention facility covers a surface area of 5.13 acres and serves a drainage area of 1.89 square miles.
The dam's spillway, measuring 50 feet in width, is uncontrolled, allowing for a maximum discharge of 2304 cubic feet per second. Despite its high hazard potential, Eastdale Creek Detention No.2 is assessed to be in fair condition. The last inspection in April 2017 revealed that the structure meets regulatory standards, with a scheduled inspection frequency of 5 years. While the dam has no outlet gates, it plays a crucial role in mitigating flooding risks in the region, protecting communities and infrastructure along Holman Draw.
Managed by the local government and regulated by the State Engineer's Office, Eastdale Creek Detention No.2 is a key component of the flood risk management system in Natrona County, Wyoming. With its strategic location and design by Shane Porter PE 9475, this dam provides essential protection against inundation and serves as a vital asset in safeguarding the community from the impacts of extreme weather events and climate variability. Its presence underscores the importance of proactive water resource management and climate resilience efforts in the face of changing 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 Eastdale Creek Detention No.2
Where does the data for Eastdale Creek Detention No.2 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 High 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.
