Summary
With a height of 6 feet and a length of 50 feet, the dam has a storage capacity of 5860 acre-feet and a surface area of 364 acres. The primary purpose of the dam is listed as "Other," with a low hazard potential and a satisfactory condition assessment as of October 2017.
Managed by the local government, Grove Lake Dam is regulated, permitted, inspected, and enforced by the Minnesota Department of Natural Resources. The dam plays a crucial role in water resource management, providing a source of water for various purposes in the surrounding area. While the dam has not been modified in recent years, it serves as a reliable structure for flood control and water storage, contributing to the overall resilience of the region's water infrastructure.
Despite its modest size and low hazard potential, Grove Lake Dam remains an important part of the water management system in Pope County. With its strategic location on the Crow River North Fork, the dam continues to support the local community by ensuring a stable water supply and protecting against potential flooding events. Water resource and climate enthusiasts will appreciate the role that Grove Lake Dam plays in maintaining the balance of water resources in this region of Minnesota.

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.
