Summary
With a height of 25 feet and a storage capacity of 40 acre-feet, this dam offers a serene and picturesque setting for water resource and climate enthusiasts to enjoy. Despite its low hazard potential, the condition of Hopper Dam is currently not rated, indicating a potential opportunity for further assessment and enhancement.
Managed by private owners, Hopper Dam has not been subject to state regulation, permitting, inspection, or enforcement. This suggests a unique opportunity for independent stewardship and conservation efforts by local water resource enthusiasts. With a surface area of 3 acres and drainage area of 50 square miles, Hopper Dam provides a valuable recreational space while also serving as a potential focal point for community engagement and environmental education initiatives. The dam's location within Boone County, Missouri, further highlights its importance within the local landscape.
As a part of the St. Louis District, Hopper Dam stands as a testament to the intersection of water resource management and recreational opportunities. While its risk assessment and management measures are currently unlisted, the dam's presence offers a potential platform for collaborative efforts among stakeholders interested in sustainable water resource practices and climate resilience. For water resource and climate enthusiasts, Hopper Dam presents a unique opportunity to explore the intersection of human-made structures and natural ecosystems, inspiring a deeper appreciation for the interconnectedness of water, land, and community.

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.
