Summary
4, also known as Texas Eastern, is a vital flood risk reduction structure located in Fisher, Athens County, Ohio. Built in 1971 by the USDA NRCS, this earth dam stands at a height of 34.2 feet and has a storage capacity of 1413.6 acre-feet. With a drainage area of 4.21 square miles and a maximum discharge capacity of 9234.1 cubic feet per second, this structure plays a crucial role in managing the flow of Biddle Creek.
The dam is regulated by the Department of Natural Resources and undergoes regular inspections to ensure its fair condition and high hazard potential are addressed appropriately. In case of emergencies, the structure has an uncontrolled spillway and outlet gates. The risk assessment for Margaret Creek Structure No. 4 is rated as moderate, indicating a level 3 hazard potential. With its primary purpose being flood risk reduction, this structure serves as a key component in the overall water resource management strategy for the region.
Water resource and climate enthusiasts will find Margaret Creek Structure No. 4 a fascinating example of engineering ingenuity and environmental stewardship. This structure not only helps in flood risk reduction but also showcases the collaborative efforts between local government, federal agencies, and design professionals. Its location in the picturesque setting of Fisher, Ohio, adds to the charm of this essential infrastructure that plays a crucial role in safeguarding the community against potential water-related hazards.

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.
