Young, R C; Dennis, W M

Studies were initiated in 1979 to evaluate the extensive aquatic macrophyte beds on the Holston River in upper east Tennessee. The primary aim of these studies was to determine if allochthonous input from drifting aquatic plant debris was a significant factor contributing to low dissolved oxygen (DO) levels in Cherokee Reservoir located downstream. This report presents the results of studies conducted in 1979-1980 to obtain refined estimate of the impact of allochthonous aquatic macrophyte input on DO levels in Cherokee Reservoir. The report also details phenological aspects of the growth and reproduction of the various species that comprise the submersed aquatic macrophyte community of the Holston River above Cherokee Reservoir and discusses the contribution of each to net primary productivity of the river. 31 references, 9 figures, 4 tables.
