Notes: Abstract The submerged macrophytes of Lake Maarsseveen I were surveyed in 1983 using SCUBA diving techniques. Only 40% of the characeans and 75% of the angiosperms detected in 1977 remained. The area colonized by submerged macrophytes was 0.45% in 1983, compared with 25.10% in 1977. The observed decreases were largely attributable to a shift of the plantcolonized areas to shallower depths. By 1983, most of the earlier predominant vegetation types had disappeared and the biomass had decreased. The decline in submerged vegetation may be attributed to increasing eutrophication, fish populations and recreational activities.
