Simmon Road Dam dam
Simmon Road Dam
Simmon Road Dam, located in Hubbard, Nebraska, is a vital piece of infrastructure designed by the USDA NRCS to manage the flow of TR-PIGEON CREEK. Completed in 1999, this earth dam stands at 41 feet tall and spans 519 feet in length, with a storage capacity of 80 acre-feet. While its primary purpose is flood risk reduction, it also serves other essential functions for the surrounding area.
Despite its importance, Simmon Road Dam currently faces challenges in its condition assessment, marked as poor during its last inspection in May 2018. With a low hazard potential, there is a need for improvements and maintenance to ensure its structural integrity and functionality. The dam is regulated by the Nebraska Department of Natural Resources, with state permitting, inspection, and enforcement in place to uphold safety standards.
For water resource and climate enthusiasts, Simmon Road Dam presents an opportunity to explore the intersection of infrastructure, environmental stewardship, and community resilience. As a critical component in managing water flow and reducing flood risks, this dam serves as a reminder of the ongoing efforts required to maintain and enhance our water management systems in the face of changing climatic conditions. Through collaboration with regulatory agencies and proactive maintenance measures, Simmon Road Dam can continue to fulfill its essential role in safeguarding the local ecosystem and population.

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 Simmon Road Dam
Where does the data for Simmon 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 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.
