Abstract
Study on the types and diversity of phytoplankton in the Koto Panjang Reservoir (Hydro-Electric
Power Plant Reservoir), Kampar, Riau, Indonesia, have been conducted from May to October 2009.
For water quality analysis, samples of water were collected every month from 6 stations on the
reservoir which consisted of 1 station on the riverine zone, 2 stations on the transition waters, and
3 stations on the lacustrine zone. The components of the samples have been taken vertically as
well as horizontally.
The diversity of the phytoplankton varies according to the zones, and there were 4 classes of
phytoplankton which were consist of 6 types of Bacillariophyta, 5 types of Chlorophyta, 3 types of
Cryssophyta, and 3 types of Cyaniphyta. Therefore, there were 17 types of phytoplankton have
been recorded. The abundance of phytoplankton at the lacustrine zone were higher, compared to
transition zone and riverine zone Such condition was estimated die to the higher of N and P ratio
on the lacustrine zone compared to the transition and riverine zone. The analysis of index
diversity, domination and similarity indicated that the condition of the reservoir still in suitable
(balance) condition for phytoplankton without dominant species.
