The aquatic vegetation of Lakelse Lake was surveyed and mapped by communities. Only four species were present in quantities covering more than 0.1 percent of the area of the lake. These were Hippuris vulgaris (4.45), Equisetum fluviatile (2.6 percent), Scirpus lacustris (2.8 percent), and Potamogeton robbinsii (9.2 percent). Tissue samples of these four species and samples of water and sediment were analyzed to determine their relative importance to the nutrient budget of Lakelse Lake during the peak of the growing season. Total sediments held between 82.1 percent and 99.9 percent of each nutrient measured; water and plant tissue were relatively insignificant. The amount of each nutrient in Lakelse found in aquatic plant tissues was from 70 to 170 times as much as that found in the phytoplankton for all nutrients measured except iron. For iron, there was 640 times as much in aquatic plants as in the phytoplankton.
