Summary
This private-owned earth dam stands at a height of 19 feet and spans a length of 690 feet, with a storage capacity of 50 acre-feet. Despite being categorized as having a high hazard potential, the dam is currently not rated for its condition assessment, highlighting the need for ongoing monitoring and maintenance.
With a primary purpose of debris control, Magasco Lake Dam plays a crucial role in managing water resources in the area. As a privately-owned structure, it is not regulated by the state and does not fall under state jurisdiction. The dam does not have a spillway and is not equipped with outlet gates, which adds to the complexity of its operation and maintenance requirements. Climate and water resource enthusiasts can appreciate the historical significance and engineering challenges associated with this important infrastructure.
Although Magasco Lake Dam lacks certain regulatory oversight and has limited data available on its current condition, its presence on Eagle Creek provides valuable insights into the management of water resources and the importance of maintaining infrastructure for debris control purposes. As climate change continues to impact water systems, understanding and monitoring structures like Magasco Lake Dam becomes increasingly critical for ensuring the safety and sustainability of our water supply in the face of evolving environmental challenges.

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.
