Nodaway Lake Dam dam
Nodaway Lake Dam
Nodaway Lake Dam, located in Maryville, Missouri, was completed in 1966 and primarily serves the purpose of flood risk reduction. With a height of 55 feet and a length of 1480 feet, this earth dam is designed to hold a maximum storage capacity of 1716 acre-feet of water. The dam also offers recreational opportunities and covers a surface area of 73 acres, making it a valuable asset for both water resource management and outdoor enthusiasts.
Owned and regulated by the State of Missouri, Nodaway Lake Dam is inspected regularly to ensure its structural integrity and safety. The dam's hazard potential is classified as high, but its condition assessment is deemed satisfactory. In the event of an emergency, the dam is equipped with valve outlet gates and an uncontrolled spillway to manage excess water flow. Overall, Nodaway Lake Dam plays a crucial role in mitigating flood risks and protecting the surrounding area from potential water-related disasters.
With its strategic location on the TR-CANAL BRANCH river/stream and its association with the Natural Resources Conservation Service as the designer, Nodaway Lake Dam is a key component of the region's water resource infrastructure. The dam's risk assessment is moderate, indicating a proactive approach to risk management. For water resource and climate enthusiasts, Nodaway Lake Dam is a noteworthy example of effective flood control measures and the importance of maintaining critical water infrastructure for the safety and well-being of communities.

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 Nodaway Lake Dam
Where does the data for Nodaway Lake 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 High 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.
