Partners

  • USFWS

Description

A railroad embankment separates the Refuge from the main channel of the river.  The role of the Refuge as a major feeding and resting area for migratory birds had been declining.  Wetlands in the southern half of the Refuge were largely unproductive for wildlife because of turbid water conditions that limited aquatic plant growth.  Wave action and rough fish contributed to the water quality problem.  In other areas of the Refuge, woody vegetation was expanding into wetland areas.
