This study was conducted to introduce the characteristics of the freshwater environment of Mulkol, considering that it is less known area about the ecosystem of the Tok Island. The salinity of freshwater in the Mulkol was less than 2.0 psu, while its periphytic algal biomass was thriving with 25.9 ${mu}g;chl-a/cm^2$. As for the nutrients in water, the content of $NH_4$ was higher than the rest of inorganic nitrogen components, and SRP and SRSi were much higher as 117.3 ${mu}$g P/l and 4,104.6 ${mu}$g Si/l respectively, than nitrogen components. Also, the ratio of N/P was found less than 1.0, revealing the condition that N was greatly limited. The high level of nutrient concentration and periphytic algal biomass at the Mulkol ecosystem could be explained as a result of natural pollution, but no full explanation was made in this study. It is a question that needs additional research in the future.
