Rottman Dam dam
Rottman Dam
Located in Pawnee, Nebraska, the impressive Rottman Dam stands as a testament to human ingenuity and environmental stewardship. Completed in 1999, this private-owned earth dam spans 395 feet in length and reaches a height of 29 feet, with a hydraulic height of 26 feet. Serving as a crucial flood risk reduction infrastructure along TR-CHATAWA CREEK, the dam has a normal storage capacity of 8 acre-feet and a maximum storage of 39 acre-feet.
Managed by the Nebraska Department of Natural Resources, Rottman Dam has been deemed to have a low hazard potential and is in satisfactory condition as of the last inspection in 2017. With its stone core and soil foundation, the dam is designed to withstand the test of time and protect the surrounding area from potential flooding events. As an essential piece of infrastructure in the region, the dam plays a vital role in water resource management and climate resilience efforts in Pawnee County.
With its commitment to state regulation, inspection, and enforcement, Rottman Dam exemplifies a proactive approach to dam safety and environmental conservation. As climate change continues to impact water resources, the importance of sustainable infrastructure like Rottman Dam cannot be overstated. As a focal point for water resource and climate enthusiasts, this dam stands as a beacon of resilience and innovation in the face of evolving environmental challenges.

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 Rottman Dam
Where does the data for Rottman 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.
