Markland Locks And Dam dam
Markland Locks And Dam
Markland Locks and Dam, located on the Ohio River in Vevay, Indiana, is a federal-owned structure managed by the US Army Corps of Engineers. Built in 1964, this concrete gravity dam serves multiple purposes, including navigation, fish and wildlife management, hydroelectric power generation, recreation, and water supply. With a total storage capacity of 640,700 acre-feet and a surface area of 19,000 acres, the dam plays a crucial role in managing water levels and discharges along the river.
The dam features two locks, each 1200 feet long and 110 feet wide, facilitating the passage of vessels through the waterway. Markland Locks and Dam is also equipped with 12 Tainter radial gates for controlled water release. Despite its significant hazard potential, the dam is regularly inspected and maintained by the US Army Corps of Engineers to mitigate flood risks and ensure its structural integrity. Emergency action plans are in place, and risk management measures are continuously implemented to address potential threats and safeguard surrounding communities.
As climate change intensifies, the importance of effective water resource management and climate resilience at facilities like Markland Locks and Dam becomes increasingly crucial. By prioritizing risk assessment, monitoring, and proactive maintenance, the US Army Corps of Engineers aims to enhance the safety and sustainability of this essential infrastructure for both current and future generations of water resource and climate enthusiasts.

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.

About Markland Locks And Dam
Where does the data for Markland Locks 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.
