Big Plum Creek dam
Big Plum Creek
Big Plum Creek, located in Lexington, Nebraska, is a significant water resource managed by the Federal Energy Regulatory Commission for its hydroelectric and irrigation purposes. The dam, completed in 1941, stands at a height of 74 feet and stretches 1794 feet in length, with a maximum storage capacity of 5164 acre-feet. Despite its low hazard potential, the dam's risk assessment is considered high, emphasizing the importance of regular inspections and risk management measures.
Owned by a public utility, Big Plum Creek is regulated by the Nebraska Department of Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safe operation. The dam serves as a crucial part of the local water supply canal system, covering a surface area of 252 acres and benefiting the surrounding community through irrigation and hydroelectric power generation. With its location in Dawson County, Nebraska, the dam plays a vital role in water management and resource sustainability in the region.
The data for Big Plum Creek highlights its significance as a key water infrastructure in Nebraska, contributing to the state's water supply and energy needs. As climate change impacts water resources, the proper management and maintenance of dams like Big Plum Creek become increasingly important to ensure the safety and reliability of water sources for both human consumption and agricultural use. With a focus on risk assessment and regulatory compliance, Big Plum Creek stands as a testament to the crucial role of water resource management in adapting to 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 Big Plum Creek
Where does the data for Big Plum Creek 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.
