Summary

The dam stands at a height of 24 feet and stretches 580 feet in length, with a storage capacity of 137 acre-feet. Situated on TR-West Mill Creek, the dam serves as a vital resource for water management in the area, with a surface area of 9.2 acres and a drainage area of 0.8 square miles.

Managed by the Iowa Department of Natural Resources, Christensen Dam is subject to state regulations and inspections to ensure its safety and functionality. Despite being rated as having a low hazard potential, the dam is considered to have moderate risk (3) due to its condition assessment not being rated. While the dam has an uncontrolled spillway and no outlet gates, it plays a crucial role in mitigating flood risks and providing essential water resources for the surrounding community.

With its strategic location and significance in water management, Christensen Dam stands as a testament to effective infrastructure planning and management in the face of climate change challenges. As a resource for fire protection, livestock, and recreational use, the dam serves as a valuable asset for the area's water resource and climate enthusiasts, highlighting the importance of sustainable water management practices 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.
