Summary

Owned by a private entity, this earth dam stands at a height of 45 feet and has a length of 385 feet, providing a storage capacity of 237 acre-feet. The dam is regulated by the Iowa Department of Natural Resources (DNR) and undergoes regular inspections to ensure its structural integrity.

With a significant hazard potential and a satisfactory condition assessment, the Lakeside Development Dam plays a crucial role in mitigating flood risks in the area. Its uncontrolled spillway and rock and soil foundations contribute to its effectiveness in managing water flow during heavy rainfall events. Located in Linn County, this dam has a surface area of 9.8 acres and serves as a key infrastructure for water resource management in the region.

For water resource and climate enthusiasts, the Lakeside Development Dam is a noteworthy structure that demonstrates the importance of proactive flood risk reduction measures. As part of the larger network of dams and reservoirs in the area, this earth dam showcases the collaboration between private owners and state regulatory agencies in safeguarding communities against potential water-related disasters. Its strategic location and design features make it a valuable asset in the overall water resource management system of Cedar Rapids, Iowa.

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.
