Summary
Built in 1966 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock, and small fish pond. Standing at a height of 20 feet and with a length of 150 feet, it has a storage capacity of 76 acre-feet and a drainage area of 1.7 square miles.
Managed by the DNRC, Blue Drew #1 has a low hazard potential and a moderate risk assessment rating of 3. While the dam is currently in good condition and has not been rated, it is subject to state regulation, permitting, inspection, and enforcement. The spillway, with a width of 100 feet, is uncontrolled, and the dam has a maximum discharge of 500 cubic feet per second.
For water resource and climate enthusiasts, Blue Drew #1 offers an intriguing case study of a privately owned dam in a rural setting. With its unique design, multiple purposes, and regulated status, this dam provides valuable insights into the intersection of water management, environmental stewardship, and regulatory compliance. As a crucial part of the local watershed, understanding the operation and maintenance of Blue Drew #1 is essential for ensuring both water security and ecosystem health 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.
