Summary
A-2-4, also known as Hoggatt, is a vital water resource structure located in Daviess, Indiana. Built in 1962 by the USDA NRCS, this earth dam serves the primary purpose of flood risk reduction along the Thompson Ditch. With a height of 21.5 feet and a length of 400 feet, Prairie Creek No. A-2-4 has a storage capacity of 518 acre-feet and a drainage area of 0.5 square miles.
This significant dam is state-regulated by the Indiana Department of Natural Resources (IDNR), with required permitting, inspections, and enforcement in place to ensure its proper function. Despite being assessed as in fair condition as of April 2013, Prairie Creek No. A-2-4 poses a significant hazard potential, with a high risk assessment rating of 2. It is essential for water resource and climate enthusiasts to stay informed about the condition and management of this structure to mitigate potential risks and ensure its continued effectiveness in flood risk reduction.
As a critical flood risk reduction measure in the area, Prairie Creek No. A-2-4 plays a crucial role in protecting the surrounding community from potential inundation events. With its stone core and rock and soil foundations, this dam is designed to withstand high discharge levels up to 1,018 cubic feet per second. Regular inspections and maintenance efforts are essential to keep this structure in optimal condition and to uphold its capacity to mitigate flood risks effectively.

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.
