Snagging, Clearing, and Shelterbelt for Flood Control, Snake River, Minnesota.

摘要

The project would involve snagging and clearing of a 50-mile reach of the Snake River between its confluence with the Red River and the city of Warren, Minnesota. All non-rooted trees and snags in the primary channel would be removed. Standing timber within the primary channel would be cut within 6 inches of the ground. Pilings and rooted stumps in the wetted part of the channel would be cut as close to ground level as practicable. Shelterbelts would be planted along reaches of the river unprotected from drifting snow. This plan would reduce flood damages, prevent the reduction in channel capacity and the clogging effect of drifting snow, and increase the amoutn of riparian habitat. The loss of large amount of aquatic and terrestrial habitat would occur along a 50-mile reach of the Snake River. The riparian wildlife community would suffer a loss in habitat values for ffeeding, cover, perching or loafing, and movement corridors. Aquatic habitat lost would include areas important to the maintenance and protection of fish populations. (Author)
