Thompson Dam 3520 dam
Thompson Dam 3520
Thompson Dam 3520, located in Stamford, Nebraska, on TR-SAPPA CREEK, is a privately owned earth dam constructed in 1960 for flood risk reduction purposes. Standing at a height of 22.4 feet, the dam has a storage capacity of 69.7 acre-feet and a surface area of 6.5 acres, serving the local community in Furnas County. The dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its structural integrity and safety.
Despite its low hazard potential, Thompson Dam 3520 is currently in poor condition as assessed during its last inspection in March 2017. Located in a rural area, the dam plays a crucial role in mitigating flood risks and protecting the surrounding environment. With a drainage area of 0.5 square miles, the dam serves as a vital infrastructure for managing water resources and maintaining water quality in the region. As a significant structure in the area, efforts are needed to improve its condition and ensure its long-term effectiveness for flood risk reduction.
As a key component in the flood risk reduction system, Thompson Dam 3520 requires ongoing maintenance and potential rehabilitation to enhance its performance and safety standards. With its importance for the local community and environment, stakeholders, including regulatory agencies and private owners, must work together to address the dam's poor condition and implement necessary risk management measures. By prioritizing the dam's upkeep and investing in its maintenance, Thompson Dam 3520 can continue to safeguard the area from potential flooding events and contribute to sustainable water resource management in Nebraska.

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 Thompson Dam 3520
Where does the data for Thompson Dam 3520 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.
