Sidney West Dam dam
Sidney West Dam
Sidney West Dam, located in Cheyenne, Nebraska, is a local government-owned structure designed by E Y GRUPE in 1958 for flood risk reduction along the TR-LODGEPOLE CREEK. The dam, primarily made of earth with buttress and stone cores, stands at a height of 26 feet and has a structural height of 31 feet. With a storage capacity of 50 acre-feet and a maximum discharge rate of 60 cubic feet per second, the dam plays a crucial role in managing water flow in the region.
Maintained by the Nebraska Department of Natural Resources, the dam is subject to state regulation, inspection, and enforcement to ensure its structural integrity and safety. With a high hazard potential, the dam has been assessed as satisfactory, with the last inspection conducted in August 2020. Despite its small surface area and drainage area, the Sidney West Dam remains a vital infrastructure for flood control in the area, highlighting the importance of water resource management in mitigating climate-related risks.
As a key component in the local flood risk reduction strategy, Sidney West Dam serves as a critical line of defense against potential flooding events. With its strategic location and design features, including a spillway and outlet gates, the dam provides essential protection for the surrounding community. Regular inspections and maintenance efforts help to ensure that the dam continues to function effectively, underscoring the importance of proactive water resource management in the face of changing climate patterns.

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 Sidney West Dam
Where does the data for Sidney West Dam 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.
