Mazour Dam 1 dam
Mazour Dam 1
Mazour Dam 1, located in Nuckolls, Nebraska, is a privately owned structure designed by USDA NRCS and regulated by the NE DNR. This earth dam, completed in 1967, serves as a flood risk reduction measure along the TR-Walnut Creek. With a height of 28 feet and a length of 510 feet, it provides a storage capacity of 353 acre-feet and covers a surface area of 15 acres within a drainage area of 2.4 square miles.
Despite its low hazard potential, Mazour Dam 1 has been assessed as being in poor condition as of March 2020. The dam has a hydraulic height of 27 feet and a structural height of 32 feet, and it is primarily composed of earth and stone materials. The dam's outdated condition assessment raises concerns about its long-term effectiveness in flood risk reduction and other purposes. Regular inspections and maintenance are crucial to ensure the dam's continued functionality and safety for the surrounding community.
As water resource and climate enthusiasts, it is important to monitor and advocate for the proper upkeep and modernization of structures like Mazour Dam 1 to effectively manage flood risks and protect local ecosystems. By staying informed about the dam's condition, inspection frequency, and emergency preparedness measures, enthusiasts can contribute to the sustainable management of water resources in the region. Additionally, engaging with regulatory agencies like the NE DNR and supporting infrastructure improvement projects can help ensure the resilience of dams like Mazour Dam 1 in the face of evolving climate 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 Mazour Dam 1
Where does the data for Mazour 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.
