Summary
Built in 1976, this earth dam with a buttress core stands at a height of 37 feet and has a length of 310 feet. The dam serves a primary purpose of recreation and offers a storage capacity of 160 acre-feet, with a normal storage capacity of 109 acre-feet.
The dam's hazard potential is classified as high, but the condition assessment as of 2007 was deemed satisfactory. The last inspection was conducted in April 2017, with a frequency of 3 years. The spillway, with a width of 20 feet, is uncontrolled. The dam is located on TR Charrette Creek and falls under the jurisdiction of the DAM AND RESERVOIR SAFETY PROG in Missouri.
Water resource and climate enthusiasts may find Castelenovo Lake Dam a fascinating structure due to its recreational purpose, design features, and risk assessment. Its location in a picturesque setting in Warren, Missouri, adds to its appeal for those interested in exploring and learning about dams and their role in managing water resources. The dam's moderate risk level and the ongoing inspections provide valuable insights into the safety and maintenance of such structures in the region.

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.
