Summary
This earth dam stands at a height of 31 feet and has a length of 600 feet, providing a storage capacity of 171 acre-feet to control runoff and protect the surrounding area from potential flooding. With a low hazard potential and a moderate risk assessment rating, this dam plays a crucial role in managing water resources in the region.
Despite being unregulated by the state and federal agencies, the Grindstone-Lost-Muddy Watershed Dam D-34 is designed to withstand the hydraulic pressures of its environment, with a spillway width of 40 feet to handle a maximum discharge of 290 cubic feet per second. The dam's primary purpose of grade stabilization is evident in its construction using stone core and soil foundation, ensuring its structural integrity over the years. With no associated structures and a condition assessment of 'Not Rated', this dam continues to serve its purpose effectively while maintaining a low risk to the surrounding community.
As a key component of the local government's infrastructure, the Grindstone-Lost-Muddy Watershed Dam D-34 stands as a testament to the collaboration between state and federal agencies in managing water resources and mitigating the impacts of climate change. With a capacity to store 97 acre-feet of water under normal conditions, this dam plays a critical role in maintaining the ecological balance of the region while protecting downstream areas from potential inundation. The dam's presence highlights the importance of proactive risk management and emergency preparedness in ensuring the safety and well-being of the local community in the face of changing environmental conditions.

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.
