Denzel Lofgreen Road Dam dam
Denzel Lofgreen Road Dam
Denzel Lofgreen Road Dam, located in Furnas, Nebraska, serves as a critical infrastructure for flood risk reduction along TR-Sappa Creek. Constructed in 1975 by Charles Wright of USDA NRCS, this earth dam stands at a height of 38 feet and spans a length of 600 feet, with a capacity to store 75 acre-feet of water. Despite its essential purpose, the dam's current condition is assessed as poor, highlighting the need for maintenance and potential upgrades to ensure its effectiveness in mitigating flood risks.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Denzel Lofgreen Road Dam plays a crucial role in safeguarding the surrounding area from potential flooding events. With a drainage area of 1.7 square miles and a maximum discharge capacity of 335 cubic feet per second, this dam serves as a vital component of the flood control infrastructure in the region. However, ongoing inspections and maintenance are necessary to address the dam's deteriorating condition and ensure its continued functionality in the face of changing climate patterns and increased water resource challenges.
As water resource and climate enthusiasts, it is essential to recognize the significance of structures like Denzel Lofgreen Road Dam in managing the impacts of extreme weather events and preserving the local ecosystem. By understanding the history, design, and current state of this dam, stakeholders can work towards implementing sustainable solutions to enhance its performance and resilience in the face of future climate uncertainties. Through collaboration with regulatory agencies and community involvement, efforts can be made to secure the long-term effectiveness of Denzel Lofgreen Road Dam in protecting the region from potential flood risks and promoting water resource sustainability.

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 Denzel Lofgreen Road Dam
Where does the data for Denzel Lofgreen Road 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 Hazard 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.
