Summary

The dam serves multiple purposes including fire protection, stock, small fish pond, and recreation. It has a structural height of 24 feet and a hydraulic height of 9 feet, with a storage capacity of 58 acre-feet and a surface area of 6 acres.

Despite being classified as having a low hazard potential and a moderate risk assessment, Tanglewood Farm has not been rated for its condition. The dam does not have outlet gates or a controlled spillway, relying instead on an uncontrolled spillway type. Although it is not regulated by the state and does not require inspections, the last inspection took place in April 2020 with a frequency of every 5 years.

Water resource and climate enthusiasts may find Tanglewood Farm an interesting site for its unique features and multi-purpose use. The dam's location on the North Fork Wolf River and its historical significance as a fire protection and recreational facility add to its allure. Monitoring and assessing the condition of this earth dam can provide valuable insights into its sustainability and resilience in the face of changing climate conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
