Gladys Black reported on fall migration, 1975, at the Red Rock Lake and Refuge, Pleasantville, Iowa. She noted it was an exceptional year for Evening Grosbeaks. She wrote a cover letter to Vernon M. Kleen regarding the impact on bird populations of blizzards, flooding from dams, and a potential nuclear power plant that might be built near the Red Rock Reservoir, December 10, 1975. Included was a sheet about the Red Rock Game Management Area published by the Iowa Conservation Commission, with a map of the area annotated by Black to show the power plant location and which areas were favored by different species of birds. This item was used as supporting documentation for the Iowa Ornithologists’ Union Quarterly field report of fall 1975.
