Dalbey Bottoms is located on the Missouri River between northwest Missouri and northeast Kansas near river mile (RM) 417.  The U.S. Army Corps of Engineers (USACE) has proposed to build a side channel chute along this stretch of the river. 

The project would be part of the Missouri River Recovery Plan aimed at restoring habitat for pallid sturgeon.  Columbia FWCO and the USACE are cooperating to study Missouri River habitat at Dalbey Bottoms before and after construction of the side channel.  Fish are being studied to assess the ecological impact of the constructed chute on pallid sturgeon and other native Missouri River fishes. 

During the month of October, Biologists from Columbia FWCO completed two sampling trips with trotlines at Dalbey Bottoms to assess abundance of adult pallid sturgeon. Thirty pallid sturgeon were captured between the two sampling trips, five of which were unmarked potentially wild fish.  Columbia plans to return in the spring to continue monitoring the fish community at Dalbey Bottoms. 

The addition of this side-channel will add to the diversity of Missouri River’s habitat.  Along with other projects up and down the river, habitat projects will aide in the recovery of the endangered pallid sturgeon as well as other species of concern.  This cooperative effort provides an avenue to apply adaptive management and supports the Service’s Strategic Habitat Conservation program.
