Summary
The dam, with a height of 33 feet and a length of 585 feet, has a storage capacity of 116 acre-feet and covers a surface area of 8.8 acres. It is regulated by the Iowa Department of Natural Resources and is subject to state inspection and enforcement. The dam poses a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
Situated on TR-NORTH WYACONDAH CREEK in Davis County, Iowa, Knapp Dam serves as a vital resource for water management in the region. It is owned by a private entity and was designed by the USDA Natural Resources Conservation Service. Despite its relatively low hazard potential, the dam has a moderate risk assessment rating, indicating the need for ongoing monitoring and risk management measures. While the dam does not have a controlled spillway, it is equipped to handle maximum storage capacity and is designed to ensure the safety and security of the surrounding area.
As a key infrastructure for water resource management, Knapp Dam plays a crucial role in providing fire protection and supporting local wildlife. With its strategic location and efficient design, the dam serves as a valuable asset for the community and highlights the importance of sustainable water management practices in mitigating the impact of climate change on water resources. Its construction and operation adhere to state regulations and inspection requirements, underscoring the commitment to safeguarding water quality and ensuring the resilience of the dam in the face of changing environmental conditions.

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.
