The research described here is part of a two year study to characterize the structure and function of the littoral macrophyte community in Jackson Lake, Wyoming. The objectives for the second year were to perform experiments to: 1) Index water movement in the littoral zone of the lake; 2) Identify the zones where the greatest plant breakage occured; 3) Determine the mechanisms and the absolute force required to break the main axis of a plant, and; 4) Measure the productivity of several species of macrophytes.
