Summary
Middle Fabius River. Standing at a height of 30 feet with a structural height of 26 feet, the dam has a storage capacity of 22 acre-feet and serves a drainage area of 120 square miles. Despite its low hazard potential, the dam has a moderate risk assessment rating of 3, indicating a need for ongoing monitoring and risk management measures.
With a spillway width of 17 feet and a maximum discharge of 43 cubic feet per second, Sidwell Dam is equipped with an uncontrolled spillway design. The dam's purpose is primarily for grade stabilization, and it boasts a surface area of 1 acre and a normal storage capacity of 13 acre-feet. While the dam has not been rated for its current condition, it is subject to periodic inspections to ensure its continued safety and functionality.
Although not under state jurisdiction, Sidwell Dam falls within the Rock Island District of the US Army Corps of Engineers and is situated in an area represented by Congressman Sam Graves (R). As a key structure in the region's water resource management, the dam plays a crucial role in flood control and water conservation efforts. Enthusiasts of water resources and climate change will find the data on Sidwell Dam to be a valuable resource for understanding the infrastructure and challenges associated with managing water resources in the area.

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.
