Gladman Miller Dam dam
Gladman Miller Dam
The Gladman Miller Dam, located in Naponee, Nebraska, is a privately owned structure designed by the USDA NRCS to reduce flood risks in the area. Completed in 1963, this earth dam stands at a height of 23 feet and has a hydraulic height of 22 feet, with a length of 460 feet. It has a normal storage capacity of 7 acre-feet and a maximum storage capacity of 179 acre-feet, serving a drainage area of 3 square miles.
Managed by the Nebraska Department of Natural Resources, the Gladman Miller Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. With a low hazard potential and fair condition assessment, the dam plays a crucial role in mitigating flood risks along the Turkey Creek. Although no spillway information is provided, the dam has been regularly inspected every five years, with the last assessment conducted in June 2018.
Overall, the Gladman Miller Dam serves as a vital infrastructure for flood risk reduction in Harlan County, Nebraska. Its construction and maintenance are overseen by the Natural Resources Conservation Service, highlighting the collaboration between private owners and government agencies to protect the local community from potential water-related disasters. The dam's strategic location and design contribute to the overall water resource management efforts in the region, making it an essential component of the area's resilience to climate-related 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 Gladman Miller Dam
Where does the data for Gladman Miller 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.
