Summary

The dam serves the primary purpose of "Other" and is classified as having a low hazard potential. It is situated on TR-ROCK CREEK and falls under the jurisdiction of the Rock Island District. While the dam has not been rated for its condition, it has not been identified as a state-regulated structure and does not require state permitting, inspection, or enforcement.

Despite being unlisted for inspection frequency and lacking a condition assessment, Jones, Clarence Dam East presents an intriguing case study for water resource and climate enthusiasts. The dam's unique buttress core type and unspecified foundation design offer opportunities for further exploration into its structural integrity and resilience to changing environmental conditions. Furthermore, the dam's location in a region with a drainage area of 150 square miles adds to the complexity of its role in managing water resources and mitigating potential risks associated with flooding and other hydrological events. Understanding the history and operational aspects of Jones, Clarence Dam East can provide valuable insights into the intersection of infrastructure development and environmental stewardship.

As the climate continues to evolve, the significance of dams like Jones, Clarence Dam East in balancing water supply, flood control, and ecosystem preservation becomes increasingly pronounced. Exploring the dam's governance structure, emergency preparedness measures, and risk management strategies can offer valuable lessons for sustainable water resource management in the face of climate uncertainty. By delving into the nuances of this unassuming but essential infrastructure, water resource and climate enthusiasts can glean valuable insights into the intricate relationship between human intervention and natural systems in the context of a changing climate.

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.
