Summary

This earth dam structure was completed in 1974 by the USDA NRCS with a primary purpose of fire protection, stock, or small fish pond. The dam stands at a height of 12.5 feet, with a length of 1050 feet and a storage capacity of 290 acre-feet.

Despite its low hazard potential, Forshier Pool is currently in poor condition as of the last inspection in October 2016. The dam has a moderate risk assessment rating of 3, indicating a need for risk management measures to be implemented. The drainage area of the pool is 0.7 square miles, with a surface area of 36 acres and a normal storage capacity of 166 acre-feet. The dam is state-regulated and falls under the jurisdiction of the Minnesota Department of Natural Resources.

Water resource and climate enthusiasts may find Forshier Pool an intriguing case study due to its unique design features and history. With its location on the Knife River in Kanabec County, Minnesota, this dam serves multiple purposes while also posing challenges in terms of maintenance and compliance with state regulations. As efforts are made to address the poor condition and moderate risk assessment, there is an opportunity to explore sustainable management practices for this important water resource in the region.

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.
