This study identifies lakes and streams which might be vulnerable to acid precipitation from the proposed Hat Creek thermal generating station. Routine water quality data collected by the Fish and Wildlife and Pollution Control Branches are used. Lakes and streams in the study area with pH =7.0 or total alkalinity =50.0 are considered to be vulnerable to acidification. Of the streams and lakes for which there are data, 60.5% (N=43) and 10.5% (N=162), respectively are considered to be vulnerable. Of those which are vulnerable, small streams fed by snow-melt during spring thaw are probably the most vulnerable. Large streams with diverse sources of water and lakes are probably not vulnerable.
