Greentree Reservoir Management

The sight of mallards falling through the trees in Arkansas’s flooded timber is a magical experience for duck hunters. At the turn of the 20th century, the Arkansas Delta and other river floodplains in the state boasted more than 5 million acres of bottomland hardwood forests. Changes in land and water use eventually destroyed or degraded more than 60 percent of this amazing bottomland ecosystem in Arkansas, In the 1950s greentree reservoirs were developed to offer reliably flooded bottomland hardwoods to mitigate these losses and provide habitat and duck hunting opportunity. But time has not been kind to Arkansas GTRs. The forest composition and health have gradually changed to less desirable conditions. Scientific information gained during the last few decades encourages a more natural and sustainable management philosophy for GTRs.

Greentree Reservoir Infrastructure Operation Status

The status of each gate controlling water on AGFC-controlled greentree reservoirs is available in the table below. If the gate cannot be closed due to hazardous conditions, extreme water levels or other obstructions, the reason for the gate being left open will be indicated. 

NOTE: Some structures may remain open by design to properly move water through an area and fill greentree reservoirs downstream of them.

The South GTR in Hentry Gray Hurricane Lake WMA will remain open throughout the 2018-19 season in an effort to prevent additional damage to trees on the area, which has seen a massive die-off from prolonged flooding during the last decade.

Mud Slough GTR in Sheffield Nelson Dagmar WMA will remain open throughout the 2018-19 season to promote the red oak saplings established on the area following a selective forest thinning in 2016. These saplings are at a critical stage when prolonged flooding can damage them and prevent the next forest of preffered oak species. .
