Summary
This state-regulated lake was completed in 1952 with a primary purpose of serving as a gravity dam with a core type of buttress. The dam stands at a height of 8 feet and a length of 80 feet, providing a normal storage capacity of 1275 acre-feet.
With a low hazard potential and a satisfactory condition assessment, Ogechie Lake serves as a vital water source for the surrounding area. Managed by the Minnesota Department of Natural Resources (MNDNR EWR), the lake covers a surface area of 410 acres and has a drainage area of 419 acres. The dam's construction by the Works Progress Administration - Civil Works (WPA-CW) showcases its historical significance and engineering feat in harnessing water resources for the benefit of the community.
Visitors to Ogechie Lake can enjoy the scenic beauty of the Rum River, with Pete Stauber (R) as the Congressional representative for the area. The lake's importance in water resource management is evident through its state jurisdiction, permitting, inspection, and enforcement processes. As a vital component of the St. Paul District's water infrastructure, Ogechie Lake stands as a testament to the harmonious relationship between human development and environmental conservation in the face of climate change challenges.

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.
