Summary
The dam stands at a height of 30 feet with a hydraulic height of 29 feet and a structural height of 31 feet. It spans 460 feet in length and has a storage capacity of 35 acre-feet, with a normal storage level of 18 acre-feet. The dam's low hazard potential and moderate risk rating make it a crucial structure for managing water resources in the area.
Despite not being regulated or inspected by state agencies, Forrest Byergo Structure Dam serves an essential purpose in stabilizing grades and protecting the surrounding area from potential flooding events. With a spillway width of 13 feet and a maximum discharge capacity of 130 cubic feet per second, the dam is equipped to handle moderate risk situations. While the dam's condition is currently not rated, its strategic location and design make it a key player in water resource management and climate resilience efforts in Nodaway County, Missouri.
As a part of the Kansas City District, the Forrest Byergo Structure Dam plays a vital role in the overall infrastructure of the area, ensuring the safety and security of local communities. With its stone core and soil foundation, the dam stands as a testament to engineering excellence and serves as a beacon of hope for water resource and climate enthusiasts looking to understand the intersection of infrastructure and environmental stewardship.

Dam Data Reference
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.
