Drohman Dam 1 dam
Drohman Dam 1
Drohman Dam 1, located in Nuckolls, Nebraska, is a privately owned structure designed by the USDA NRCS to assist in flood risk reduction along the TR-Little Blue River. Completed in 1970, this earth dam stands at a height of 20 feet and spans 250 feet in length, with a storage capacity of 59 acre-feet. The dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its structural integrity.
With a low hazard potential and a satisfactory condition assessment as of April 2020, Drohman Dam 1 plays a crucial role in protecting the surrounding area from potential flooding events. The dam's primary purpose extends beyond flood control to include other uses, making it a versatile and valuable resource for water management in the region. As part of its operations, the dam is subject to state jurisdiction and permitting, with enforcement measures in place to maintain compliance with regulatory standards.
As a key component of the water infrastructure in Nuckolls County, Drohman Dam 1 serves as a testament to the collaborative efforts between private ownership and government agencies in safeguarding communities against the impacts of extreme weather events. Its location along the TR-Little Blue River underscores the importance of proactive measures in managing water resources and mitigating climate-related risks. With ongoing monitoring and maintenance, Drohman Dam 1 continues to stand as a vital asset in the region's resilience against potential flood threats.

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 Drohman Dam 1
Where does the data for Drohman Dam 1 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.
