Description and specifications are presented for the laser monitoring system, designed using Leica DISTOTM plus rangefinders. This system provides all-season monitoring of positions of both shore and river walls of the deep-water single-lift of the Ust'-Kamenogorsk lock. Results are presented of long-term measurements of the lock walls deflections due to both seasonal (winter-summer) temperature changes and filling-emptying the lock.
