Summary

Francisville, Missouri, along the TR-DES MOINES RIVER, was completed in 2001 by the USDA NRCS. This private dam serves multiple purposes, including fire protection and providing water for stock or small fish ponds. With a structural height of 35 feet and a length of 325 feet, this earth dam holds a normal storage capacity of 14 acre-feet and a maximum storage capacity of 19 acre-feet.

The dam's spillway, with a width of 10 feet, is uncontrolled, and the outlet gates are also uncontrolled. Despite its low hazard potential, Ed Riney Dam is considered to have a moderate risk, with a risk assessment rating of 3 out of 5. The dam is not currently regulated by the state and has not been inspected since its completion in 2001. While the dam's condition is listed as "Not Rated," it remains an important structure for water resource management and climate resilience in the region.

Water resource and climate enthusiasts will be intrigued by Ed Riney Dam's design and purpose, as it contributes to the local ecosystem and provides essential services for the community. With its location in Clark County, Missouri, this dam plays a vital role in maintaining water levels for irrigation, fire protection, and agricultural activities. As a privately owned structure, Ed Riney Dam stands as a testament to sustainable water management practices and the importance of maintaining infrastructure for the benefit of both people and the environment.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
