At the inlet, where silt is deposited, and where the lake water is aerated and mixed with that of the inlet stream P. amplifolius grew in 5-6 feet of water, but elsewhere it grew in water 1-2 feet deep near the shoreline. 3. Meach Lake. Figure 4 In areas 1 and 3 a total of 34 species was found and the total abundance numbers 287 and 306 respectively, indicate that many of the species were present at maximum density on the scale used. By contrast, area 5 had only five species and a total abundance number of only 35. The numerical values emphasize that area 3 (Mac- donald Bay) had a high density of aquatics, while area 5 consisting of rocky exposed shore, had a low aquatic plant density. The range of aquatic plant abundance varied between these extremes in the other areas of the lake. Area 9 may have originally supported more aquatic vegetation but natural conditions have been altered by the use of rock fill in road construction along the shore and by the dumping of sand for beaches. The water entering Meach Lake from Har- rington flows through very dense beds of over 30 species of aquatic plants and presumably seeds from these plants are distributed throughout the.
