Summary
Completed in 1967, this earth dam stands at a height of 28 feet and boasts a storage capacity of 330 acre-feet, with a normal storage level of 257 acre-feet. The dam is situated on the TR-BOEUF CREEK, within the St. Louis District, and is owned privately, catering to the needs of the local community and water enthusiasts alike.
Despite being privately owned, Boston Lake Dam holds a low hazard potential and has not been rated for its condition assessment. With no state regulation, inspection, or enforcement in place, the dam's primary purpose remains focused on recreation, while also serving as a water supply source. The dam's strategic location and design make it a significant asset for the area, providing not only recreational opportunities but also contributing to the overall water resource management in the region.
While Boston Lake Dam may not be under state jurisdiction, its importance in providing both recreational and water supply benefits cannot be understated. With a rich history dating back to its completion in 1967, this earth dam continues to play a vital role in the local community's water resource and climate resilience efforts. As a key feature on the TR-BOEUF CREEK, Boston Lake Dam stands as a testament to the interconnectedness of water resources and climate management, highlighting the need for sustainable and effective infrastructure to meet the region's growing demands.

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.
