The Primary production and budget of organic carbon at rainy and dry period was surveyed to evaluate the contribution of primary production in Paldang Reservoir. Primary productivity of phytoplankton showed remarkable differences depending on sampling dates and sites, ranged from 110 to 2,701 ㎎Cm^(-2)day^(-1). In the rainy period of April and August when there had been frequent rainfall resulting short hydraulic retention time and low algal biomass in Paldang Reservoir, autochthonous organic carbon occupied very low ratio, forming approximately 7 percent of total inflow of organic carbon. However in June when it almost never rained and dominant algal species changed from diatoms to green algae and small flagellates, autochthonous organic carbon from primary productivity of phytoplankton formed 29 percent of total inflow of organic carbon.

Seasonal and vertical distributions of dissolved and particulate organic carbon were investigated from May 1995 to March 1997 in n deep mesotrophic reservoir, Lake Soyang, POC contentrations at the dam site ranged from 0.1 to 1.8 mgC/L and DOC concentrations ranged from 1.4 to 4.9 mgC/L. POC concentrations in the surface layer were higher in the season of cyanobacterial bloom, July to September. High POC was observed at the depth of 30 to 60m after storm runoff in summer monsoon season. Turbid storm runoff formed intermediate current laden with much particulate materials from terrestrial sources. The vertical and seasonal variation of DOC was smaller than POC. Higher DOC was observed near the lake bottom which implies sedimentation and degradation of much organic detritus at the bottom. The ratio of DOC : POC varied from 2 to 60, and the ratio was lowest in September 1995 when algal density was highest. DOC : POC ratio of the main inflowing river, the Soyang River, varied from 1 to 10, and the ratio was low in storm runoff when the POC concentration was high.
