Summary
Completed in 1978, this 25-foot tall structure spans 480 feet in length and has a drainage area of 300 acres. With a storage capacity of 36 acre-feet, the dam serves the purpose of regulating water flow and preventing erosion in the surrounding area.
Despite its low hazard potential, this dam has been classified as having a high risk level, warranting attention for risk management measures. The structure, made of stone core and soil foundation, currently holds a "Not Rated" condition assessment. While it does not have a spillway, outlet gates, or locks, it is essential for maintaining the water levels and flow in the region. As the only dam on the TR-Weldon River, its strategic location and functions make it a critical piece of infrastructure for water resource management in the area.
Managed by the Rock Island District of the US Army Corps of Engineers, Wash Twp Site Ca-29-6003-129-010-1 is integral for maintaining the ecological balance and water quality of the surrounding environment. As climate change continues to impact water resources, the proper maintenance and upkeep of this dam are crucial for ensuring the safety and sustainability of the watershed. With a focus on risk assessment and management, this structure plays a vital role in mitigating potential hazards and ensuring the continued resilience of the local water supply.

Dam Data Reference
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.
