About this dam

Tyson Lagoon Dam - Cell 3

Tyson Lagoon Dam - Cell 3, located in Madison, Nebraska, is a privately owned earth dam that was completed in 1980. With a height of 14 feet and a length of 4988 feet, the dam serves a primary purpose of "Other" and has a normal storage capacity of 349 acre-feet. Situated on TR-Union Creek, this dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its structural integrity.

The dam's hazard potential is classified as "Significant," but its condition was assessed as "Satisfactory" during the last inspection in June 2020. Despite its age, Tyson Lagoon Dam - Cell 3 continues to effectively manage water resources in the region, with a surface area of 33.5 acres and a drainage area of 0.07 square miles. The dam's location in Congressional District 01, Nebraska, highlights its importance in water resource management and climate resilience efforts in the area.

As an essential component of the local infrastructure, Tyson Lagoon Dam - Cell 3 plays a crucial role in protecting the surrounding community from potential flooding events. Its satisfactory condition and regular maintenance demonstrate a commitment to ensuring the safety and reliability of this earth dam for years to come. Water resource and climate enthusiasts can appreciate the significance of this dam in maintaining the ecological balance and safeguarding the region's water supply.

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 Tyson Lagoon Dam - Cell 3

Where does the data for Tyson Lagoon Dam - Cell 3 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 Significant 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.
