Summary
Built in 1972 by the USDA NRCS, this earth dam stands at a height of 37 feet and spans 451 feet in length, with a storage capacity of 85 acre-feet. Serving primarily for fire protection and as a small fish pond, the dam plays a crucial role in managing water resources in the area.
With a low hazard potential and a moderate risk assessment, Lake Morris Erosion Control Site 3 is designed to withstand potential challenges while ensuring the safety of the surrounding community. Despite not being rated for its current condition, the dam is regularly inspected and maintained by the Iowa DNR to uphold its functionality and structural integrity. The site also falls within the regulatory jurisdiction of the state, with permitting, inspection, and enforcement processes in place to ensure compliance with safety standards.
As a key component in the water management system along TR-Little Whitebreast Creek, Lake Morris Erosion Control Site 3 serves as a critical infrastructure for flood control and water supply in the region. With its strategic location and design, the dam not only mitigates erosion but also contributes to the overall ecosystem health and sustainability of the area. This site stands as a testament to the collaborative efforts of various agencies and stakeholders in safeguarding water resources and addressing climate challenges in Iowa.

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.
