Col. Charles D. Maynard Lock And Dam dam
Col. Charles D. Maynard Lock And Dam
Col. Charles D. Maynard Lock and Dam, located in Pine Bluff, Arkansas, is a federal structure managed by the US Army Corps of Engineers. Completed in 1968, this concrete gravity dam serves multiple purposes including navigation, irrigation, and recreation. With a height of 39 feet and a length of 7780 feet, it has a maximum storage capacity of 68,500 acre-feet, providing important water management capabilities for the Arkansas River.
The dam's controlled spillway, with a width of 900 feet, helps manage water levels and prevent flooding, while the single lock allows for navigation along the river. Despite its significant hazard potential, the US Army Corps of Engineers actively manages dam-related flood risks through monitoring, maintenance, and emergency preparedness efforts. By engaging with local emergency managers and the public, they work to raise awareness and ensure readiness in the event of a dam-related emergency.
Overall, the Col. Charles D. Maynard Lock and Dam plays a crucial role in water resource management and flood control in the region. Its strategic location and multi-purpose design make it a key asset for the community, with ongoing efforts to enhance its risk management measures to ensure the safety and resilience of the surrounding area.
Dam data reference
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.
- 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.
- 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.
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, environmental 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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Col. Charles D. Maynard Lock And Dam
Where does the data for Col. Charles D. Maynard Lock And Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
