Summary
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 The dam's outdated condition assessment raises concerns about its long-term effectiveness in flood risk reduction and other purposes.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
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
