About this dam

Horne Lake Dam

Horne Lake Dam, located in Rison, Arkansas, was completed in 1955 and serves as a key structure for recreational purposes and water supply in the area. The dam is privately owned and stands at a height of 28 feet with a hydraulic height of 25 feet, making it an important asset for managing water resources in the region. With a normal storage capacity of 70 acre-feet and a maximum discharge of 700 cubic feet per second, the dam plays a vital role in regulating water levels and ensuring sustainable water supply for the surrounding area.

Managed by the Arkansas Natural Resources Commission, Horne Lake Dam is subject to regular state inspections, enforcement, and permitting to ensure its structural integrity and compliance with regulations. Despite being classified as having a low hazard potential, the dam's condition assessment is currently not rated, highlighting the need for ongoing monitoring and maintenance to ensure its long-term safety and effectiveness. The dam's location on Derrieusseaux Creek-TR adds to its significance in managing water resources and protecting against potential risks in the area.

In addition to its recreational and water supply purposes, Horne Lake Dam also serves as a critical infrastructure for the community, with a storage capacity of 100 acre-feet and a surface area of 12.8 acres. It is situated within the Little Rock District of the US Army Corps of Engineers and is a key component in the overall water management system of Grant County, Arkansas. Despite its low hazard potential, ongoing assessments and risk management measures are essential to ensure the dam's continued functionality and safety for both water resource and climate enthusiasts in the region.

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.

FAQ

About Horne Lake Dam

Where does the data for Horne Lake 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 Low 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.
