Title
Periodic stream temperature data (1957-1983) in the Andrews Experimental Forest
Abstract
Weekly maximum and minimum water temperatures were recorded at the gaging stations on three small watershed (Watersheds 1, 2, and 3) in the Andrews Experimental Forest from 1959 through 1966. The period from 1959 to 1962 represents before-logging conditions. Watershed 2, which remained undisturbed through this period, served as a control in statistical comparisons. Temperatures continued to be recorded from these watershed until 1981. From 1964 to 1980, temperatures were recorded at watersheds 6, 7, and 8. Watershed 10 temperatures were recorded from 1981 through 1983.
