Mayfield Dam dam
Mayfield Dam
Mayfield Dam, located in Dawes, Nebraska, is a privately owned structure designed by the USDA NRCS for irrigation purposes. Completed in 1950, this earth dam stands at a height of 15 feet and has a maximum storage capacity of 144 acre-feet. The dam's primary purpose is to provide water for irrigation in the area, with a normal storage capacity of 84 acre-feet and a surface area of 16 acres.
Managed by the NE DNR, Mayfield Dam is regulated and inspected by the state, with a low hazard potential but a poor condition assessment as of the last inspection in April 2019. Despite its condition, the dam still plays a vital role in water resource management in the region, with a drainage area of 1.1 square miles and a maximum discharge capacity of 643 cubic feet per second. The dam's location on the TR-CHADRON CREEK serves as a crucial water source for agricultural activities in the surrounding area.
While Mayfield Dam may face challenges in terms of its condition, its importance in providing water for irrigation cannot be understated. As climate change continues to impact water resources, structures like Mayfield Dam will play a crucial role in managing and distributing water in a sustainable manner. Climate enthusiasts and water resource experts alike can appreciate the significance of structures like Mayfield Dam in ensuring water security for agricultural operations in the region.

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 Mayfield Dam
Where does the data for Mayfield 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.
