Summary
This Earth dam, completed in 1878, serves as a Fish and Wildlife Pond, providing essential habitat for local wildlife and recreational opportunities for visitors. With a maximum storage capacity of 3,075 acre-feet and a normal storage of 600 acre-feet, the reservoir covers a surface area of 130 acres and has a drainage area of 74.7 square miles.
The dam, standing at a height of 22 feet and a hydraulic height of 12.5 feet, poses a high hazard potential but is currently assessed as satisfactory in condition. With a moderate risk assessment rating, the reservoir has a regulated spillway type and a history of uncontrolled spillway events. Regular inspections, conducted every two years, ensure the dam's structural integrity and the safety of the surrounding communities. Despite its age, Framingham #1 Reservoir continues to play a crucial role in water resource management, climate adaptation, and environmental conservation efforts in the region.
For water resource and climate enthusiasts, Framingham #1 Reservoir offers a fascinating case study in sustainable water management and dam safety practices. As a vital source of water for fish and wildlife, as well as a popular recreational destination, this historic reservoir exemplifies the intersection of human development and natural ecosystems. By understanding the reservoir's design, purpose, and risk management measures, enthusiasts can gain valuable insights into the challenges and opportunities of maintaining essential water infrastructure in a changing climate.

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.
