Summary

Designed by the USDA NRCS, this earth dam serves multiple purposes including fire protection, stock, and small fish pond management. With a height of 32 feet and a length of 315 feet, the dam has a storage capacity of 34 acre-feet and covers a surface area of 2.6 acres. Situated on TR-Sugar Creek, the dam is regulated by the Iowa DNR and undergoes regular inspections and enforcement to ensure its safety and compliance with state regulations.

Despite being classified as having a low hazard potential, Beattle Dam poses moderate risks according to a risk assessment rating of 3. While the dam's condition assessment is currently listed as "Not Rated," it remains under the jurisdiction of the Iowa DNR for permitting, inspection, and enforcement purposes. The dam's spillway type is uncontrolled, and it does not have outlet gates or associated structures. Though lacking certain risk management measures and emergency action plans, Beattle Dam continues to play a crucial role in water resource management and ecosystem conservation efforts in the region, benefiting local wildlife and agriculture.

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.
