Prouty Irrigation Dam dam
Prouty Irrigation Dam
The Prouty Irrigation Dam, located in Holt, Nebraska, is a key structure designed for irrigation purposes along the Young Creek. Constructed in 1981, this earth dam stands at a height of 23 feet and has a hydraulic height of 22 feet, providing a storage capacity of 52 acre-feet. Despite its low hazard potential, the dam is currently assessed to be in poor condition, highlighting the need for regular inspections and maintenance to ensure its structural integrity and safety.
Managed by a private owner, the Prouty Irrigation Dam falls under state jurisdiction and regulation by the Nebraska Department of Natural Resources. With a drainage area of 1.2 square miles and a maximum discharge capacity of 187 cubic feet per second, this dam plays a crucial role in supporting agricultural activities in the region. However, the dam's poor condition underscores the importance of proactive risk management measures and emergency preparedness to mitigate potential hazards and ensure the continued functionality of this vital water resource infrastructure.
As a focal point for water resource and climate enthusiasts, the Prouty Irrigation Dam serves as a reminder of the intricate balance between human intervention in water management and the need for sustainable infrastructure practices. With its historical significance and operational challenges, this dam presents an opportunity for stakeholders to collaborate on enhancing its safety, efficiency, and resilience in the face of changing environmental conditions. By prioritizing regular assessments, maintenance, and risk mitigation strategies, the Prouty Irrigation Dam can continue to support agricultural activities and contribute to the overall water management efforts in the region.

About Prouty Irrigation Dam
Where does the data for Prouty Irrigation 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 below 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.

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.
