A draft supplemental environmental assessment for repairs to the Ponca State Park backwater site in Dixon County, Neb. is currently available for public review. The EA evaluates the environmental impacts of repairing damages that occurred to the chute during the 2011 Missouri River flood. These repairs are needed to restore the intended habitat function of the Ponca site and prevent it from degrading further. Comments are due August 26, 2015.
A draft supplemental environmental assessment for adaptive management to the Sandy Point Bend chute complex in Harrison County, Iowa is currently available for public review. The EA evaluates the environmental impacts of adaptive management measures to maintain shallow water habitat quality within the chute complex and prevent impacts to the adjacent navigation channel. Comments are due August 21, 2015.
Releases began ramping down at the three Tri-Lakes dams at the beginning of July to slow the rate of elevation drop in the reservoirs. After releases were reduced, rainfall runoff increased inflows to Chatfield and Bear Creek causing the reservoirs to experience slight pool rises. Both reservoirs have begun falling again.
