Summary

Doutt Upground Reservoir, located in Delaware, Ohio, is a key water supply source designed by MS Consultants, Inc. It was completed in 2014 and boasts a dam height of 46 feet and a storage capacity of 32,028 acre-feet. The reservoir covers 842 acres with a drainage area of 1.33 square miles and serves the primary purpose of water supply for the local government.

Managed by the Department of Natural Resources in Ohio, this reservoir has a high hazard potential but is currently assessed as satisfactory in condition. The dam underwent its last inspection in December 2018 and is subject to regular maintenance with an inspection frequency of 5 years. Despite the potential risks, the reservoir meets guidelines for emergency action preparedness and continues to play a vital role in water resource management in the region.

With its strategic location along Ottawa Creek, John R. Doutt Upground Reservoir offers a critical water supply solution for the community of Prospect. Its significant storage capacity and reliable infrastructure underscore its importance in maintaining water security for the area, making it a key asset for both water resource and climate enthusiasts alike.

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.
