Man-made modifications of trout habitat in the upper mile (section A) of Lawrence Creek were followed by significant increases in standing crops of wild brook trout (Salvelinus fontinalis), angler use, and yield. During the 3 years (1965-67) after completion of development, average annual biomass of age 0 and older trout was 41% greater than the average for the 3-year predevelopment period (1961-63). Biomass of age I and older trout increased by an average of 57% and biomass of age II+ trout increased by an average of 141%. An obvious stockpiling effect was evident, a result primarily of improved overwinter survival after development.
