GROUND WATER FOR PUBLIC WATER SUPPLY AT WINDIGO, ISLE ROYALE NATIONAL PARK, MICHIGAN, 1982

By: Grannemann, N. G., and Twenter, F. R.

Abstract

Three test holes drilled at Windigo in Isle Royale National Park in 1981 indicate that the ophitic basaltic lava flows inderlying the area contain little water at depths less than 175 feet and cannot be considered a source for a public water supply. The holes were 135, 175, and 71 feet deep. One hole yielded about 1 gallon of water per minute; the other two yielded less. Glacial deposits seem to offer the best opportunity for developing a ground-water supply of 5 to 10 gallons per minute.
