Brook‐trout habitat in Big Hudson Brook was destroyed in 1950 by extensive bulldozing in preparation for pulpwood driving. Following bulldozing, the brook had no well‐defined channel at low water levels, water temperatures reached the mid‐seventies, and the small flow seeped through bottom rubble. Although restoration of original habitat conditions was impossible, an attempt was made, using a bulldozer, to improve trout‐stream habitat that had been destroyed earlier by bulldozing. Seventy‐one wing deflectors, 10 rock dams, and 6 spring holes were created by a single bulldozer in 3 working days. Evaluation of the work 2 years later showed that 63 deflectors had successfully narrowed stream flow or created pools, rock dams were largely unsuccessful, and pools created by excavation of spring areas commonly harbored trout during warm summer weather.
