Summary

The dam stands at a height of 9 feet and has a length of 45 feet, serving as a vital water resource on the Rush River. With a storage capacity of 5500 acre-feet, the lake provides a normal storage capacity of 2772 acre-feet for the surrounding area.

Despite its historical significance, Titlow Lake is currently assessed to be in poor condition with a low hazard potential. The dam is regulated by the Minnesota Department of Natural Resources and undergoes regular inspections to ensure its safety and integrity. The last inspection took place in June 2008, with a scheduled frequency of every 8 years. While the dam's condition may be concerning, its importance for water resource management in the region cannot be understated.

For water resource and climate enthusiasts, Titlow Lake represents a unique intersection of history, infrastructure, and environmental stewardship. As efforts continue to maintain and improve the dam's condition, this picturesque lake remains a key component of the local landscape, providing both recreational opportunities and essential water storage for the community. As discussions surrounding dam safety and climate resilience evolve, Titlow Lake stands as a reminder of the delicate balance between human development and natural resource conservation.

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.
