Summary
This Earth-type dam stands at a height of 10 feet and spans 300 feet in length, with a poor condition assessment and a significant hazard potential. Despite being state-regulated and inspected, Mosher poses a risk due to its age and condition, making it a point of concern for water resource and climate enthusiasts.
The dam, owned privately, sits in a picturesque setting but raises issues regarding its safety and maintenance. With a history dating back over a century, Mosher's current state calls for attention and potential risk management measures to ensure the safety of its surroundings and the downstream area. Climate change impacts and increasing water demands further highlight the importance of monitoring and maintaining structures like Mosher to safeguard water resources and prevent potential disasters.
As a focal point for recreation in the area, Mosher's significance extends beyond its physical presence. The dam's condition assessment, emergency action plan preparedness, and hazard potential underscore the need for ongoing monitoring and risk assessment to protect both the environment and the community. Climate enthusiasts and water resource advocates alike can find common ground in advocating for the sustainable management of structures like Mosher to ensure a resilient and safe water future.

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.
