Summary

Completed in 1972, this earth dam stands at a height of 21 feet and spans a length of 380 feet, with a storage capacity of 62 acre-feet. The primary purposes of this dam are fire protection, stock, and small fish pond management, making it a crucial asset for water resource management in the area.

Managed by the Iowa DNR and regulated by state authorities, Lake Morris Erosion Control Site 8 has a low hazard potential and a moderate risk assessment rating. Despite its condition being unassessed, the dam serves as a key component in maintaining the health of the TR- Little Whitebreast Creek and its surrounding environment. With a surface area of 2.6 acres and a drainage area of 0.17 square miles, this dam plays a significant role in controlling debris and maintaining water quality in the region.

While the dam's specific inspection and maintenance details are not provided, its location in the Kansas City District highlights its importance as a part of the local water infrastructure. With its earth construction and soil foundation, Lake Morris Erosion Control Site 8 stands as a testament to the collaborative efforts of local government and federal agencies in preserving water resources and climate resilience 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.
