PROJECT DATA

   Pool limits for the projects located on the Arkansas River are designed to keep the water levels in the river deep enough to allow for navigation up and down the river.  These pool limits DO NOT provide for any type of flood control.  The values for the pool limits provide a range of flow dependent elevations at which the project should be maintaining it's pool.

  The table below illustrates the what the pool limits are for each of the district's projects along the Arkansas River at various flowrates.

Inflow (cfs) 0-45,000 45,000-100,000 100,000+ open river
