About this dam

Mestl South Lagoon Dam

Mestl South Lagoon Dam, located in Red Willow, Nebraska, is a privately owned structure that plays a crucial role in managing water resources in the area. Completed in 1970, this Earth-type dam stands at a height of 21.2 feet and has a storage capacity of 153.5 acre-feet, with a normal storage level of 130.8 acre-feet. Situated on the TR-Republican River, this dam helps regulate the flow of water and provides essential support for the surrounding ecosystem.

Managed by the Nebraska Department of Natural Resources, Mestl South Lagoon Dam is regularly inspected to ensure its structural integrity and overall safety. With a low hazard potential and a satisfactory condition assessment, this dam serves its primary purpose effectively. Despite its simple design, consisting of buttress and stone core types on a soil foundation, Mestl South Lagoon Dam is a vital component in the local water management infrastructure.

Climate and water resource enthusiasts will appreciate the significance of Mestl South Lagoon Dam in maintaining water quality and quantity in the region. With its efficient operation and state-regulated status, this dam stands as a testament to responsible water resource management. The strategic location of this Earth-type dam on the TR-Republican River demonstrates a commitment to sustainable practices and environmental stewardship in the face of changing climate 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.

FAQ

About Mestl South Lagoon Dam

Where does the data for Mestl South Lagoon 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 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.
