Summary
Marys, Missouri, is a private structure built in 1942 primarily for recreational purposes. The dam, standing at a height of 32 feet and with a storage capacity of 120 acre-feet, is situated on the South Fork Jonca Creek. Despite its recreational focus, the dam is classified as having a high hazard potential, although its condition assessment is currently listed as "Not Rated."
Owned and operated privately, Pineview Dam does not fall under state jurisdiction and is not regulated or permitted by state agencies. The dam's design includes an earth core with buttress foundations, highlighting its engineering considerations for stability and safety. With a drainage area of 280 square miles and a surface area of 7 acres, Pineview Dam plays a crucial role in managing water resources in the region, especially for recreational activities in the vicinity.
For water resource and climate enthusiasts, Pineview Dam offers a fascinating insight into the intersection of infrastructure development and environmental stewardship. As a significant feature in the Kansas City District, the dam contributes to the management of water flow and storage in the area, while also providing opportunities for outdoor recreation. Its historical significance, dating back to the 1940s, adds a layer of heritage to its functionality, making it a compelling site for further exploration and study in the realm of water resource management and climate resilience.

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.
