Summary
Constructed in 1972 by the USDA NRCS, this earth dam stands at a height of 35 feet and spans 670 feet in length, providing a storage capacity of 324 acre-feet to the surrounding area. The dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections to ensure its structural integrity.
Situated along the TR-Little Whitebreast Creek, Lake Morris Erosion Control Site 7 serves as a low hazard potential structure with a moderate risk assessment rating. While the dam itself has not been rated for its current condition, it continues to fulfill its primary purpose effectively. Despite lacking certain emergency preparedness measures such as an EAP and updated contact information, the dam remains a crucial asset for water resource management in the region. With its controlled spillway and soil foundation, Lake Morris Erosion Control Site 7 represents a key component of the local infrastructure for both environmental conservation and community safety.
As water resource and climate enthusiasts, the significance of Lake Morris Erosion Control Site 7 lies in its role as a sustainable solution for erosion control and water management in the area. With a surface area of 12.5 acres and a drainage area of 1.16 square miles, this dam contributes to the overall ecological balance of the region. While it may lack certain risk management measures, the dam's functionality and purpose highlight the ongoing need for proactive monitoring and maintenance to ensure its long-term effectiveness. As stewards of our natural resources, it is crucial to recognize and support initiatives like Lake Morris Erosion Control Site 7 that contribute to the resilience of our water ecosystems in the face of changing climate patterns.

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.
