Summary
Built in 1986 by the USDA NRCS, this earth dam serves a dual purpose of providing a habitat for fish and wildlife while stabilizing the grade in the surrounding area to prevent erosion.
With a height of 34 feet and a length of 530 feet, this dam boasts a storage capacity of 33 acre-feet, making it an essential feature in managing water resources in the region. The dam is situated on TR-EAST FORK LOST CREEK and is designated as having a low hazard potential with a moderate risk assessment. Despite not being regularly inspected or rated, the dam remains a crucial component in the local ecosystem, providing valuable benefits to both wildlife and the community.
Although lacking in certain regulatory certifications and emergency preparedness measures, the Grindstone-Lost-Muddy Watershed Dam Lt-159 serves as a prime example of private stewardship in water resource management. Its presence underscores the importance of sustainable practices in maintaining a healthy environment for future generations to enjoy.

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.
