Summary
Built in 1955, this earth dam stands at a height of 100 feet and stretches 1500 feet in length, holding a maximum storage capacity of 36,368 acre-feet. Its primary purpose is to provide recreational opportunities for visitors while also serving as a crucial water source for the region.
Managed by the Dam and Reservoir Safety Program, Fellows Lake Dam has a high hazard potential but is currently in satisfactory condition according to the last assessment in 2007. With a spillway width of 700 feet and a maximum discharge capacity of 32,900 cubic feet per second, the dam is equipped with valve outlet gates for water control. The surrounding area boasts a surface area of 812 acres and a drainage area of 12,858 acres, highlighting the critical role the dam plays in managing water resources for the community.
For water resource and climate enthusiasts, Fellows Lake Dam serves as a fascinating case study in dam management and infrastructure resilience. With regular inspections and a moderate risk assessment rating, the dam stands as a testament to the importance of proper maintenance and monitoring in ensuring the safety and sustainability of water resource structures. Its strategic location on the Little Sac River further underscores its significance in the local ecosystem, making it a valuable asset for both recreation and water management in the region.

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.
