Summary

Constructed in 1945, this Earth dam stands at 25 feet high and spans 360 feet in length, with a storage capacity of 544 acre-feet. The primary purpose of Engineer Lake is for recreation, offering a surface area of 23 acres for water enthusiasts to enjoy.

The lake is situated on Tr Big Creek and is overseen by the US Army for operations, design, construction, and regulatory purposes. Despite being categorized as low hazard potential, the risk assessment for Engineer Lake is moderate. Although the last inspection was conducted in 1981, with an inspection frequency of 4 years, the condition assessment is currently not available. With a spillway width of 30 feet and a maximum discharge of 1100 cubic feet per second, Engineer Lake provides both a safe and enjoyable environment for visitors.

Overall, Engineer Lake offers a picturesque setting for outdoor activities in the Bloomer area, with its recreational facilities and tranquil waters attracting both locals and tourists alike. As a key water resource managed by the US Army, the lake serves as a vital hub for leisure and enjoyment while also ensuring the safety and well-being of its visitors through regular hazard assessments and risk management measures.

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.
