This paper presents results of small scale model experiments to determine optimum location of tree rows for increasing snowdrift volumes in pit reservoirs. These small scale model studies suggest that when a tree row is used to accumulate snow in a pit reservoir, the only effective location as at the upwind edge of the pit. Trees will draw water from the reservoir, reducing the volume available for other uses. However, amounts are of the same order as evaporation rates, and are likely to be less than seepage losses, unless the pit is lined. Low-use evergreen species reduce this water use to approximately half the amount required by cottonwood, poplar or willow. The benefits of vegetative barriers – as wildlife habitat, for example—may offset the difficulties of establishing and maintaining a living barrier.
