Summary
Watershed Site 3-1-1 is a vital resource managed by the local government for fire protection, stock, and small fish pond purposes. Constructed in 1984 by the USDA NRCS, this earth dam stands at a height of 44 feet and stretches 490 feet in length, providing storage for up to 435 acre-feet of water. With a low hazard potential and moderate risk assessment, this dam plays a crucial role in flood risk reduction for the surrounding area.
Situated along the TR- MC PHERRON CR. stream, this dam covers a drainage area of 0.89 square miles and boasts a surface area of 28.8 acres. Despite being uncontrolled, the spillway of Waubonsie Cr. Watershed Site 3-1-1 ensures the safe release of excess water during heavy rainfall events. Managed by the Iowa DNR, this dam undergoes state inspection, enforcement, and regulation, highlighting its importance in water resource management and climate resilience efforts in the region.
As a part of the Omaha District, Waubonsie Cr. Watershed Site 3-1-1 stands as a testament to the collaborative efforts between local and federal agencies in safeguarding water resources and enhancing the overall environmental quality of the area. With its strategic location and purposeful design, this dam serves as a critical infrastructure for sustainable water management and ecosystem protection in Bartlett, Iowa.

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.
