Summary
The dam at Pleasant Lake is a Timber Crib type, standing at a height of 15 feet and a length of 50 feet. Completed in 1900, the dam has a storage capacity of 1,541 acre-feet, with a normal storage level of 24 feet and a surface area of 339 acres.
Despite its age, Pleasant Lake Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The last inspection date recorded was in 1899, with a scheduled inspection frequency of 12 months. Situated on the Sixteenth Stream, the dam at Pleasant Lake provides a fascinating glimpse into the history and importance of water resource management in the region.
For water resource and climate enthusiasts, Pleasant Lake offers a unique opportunity to study the intersection of hydroelectric power generation, dam infrastructure, and environmental regulations. With its picturesque location and historical significance, Pleasant Lake serves as a valuable case study for understanding the complexities and challenges of managing water resources in a sustainable and responsible manner.

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.
