The objectives of this study were to analyze the longitudinal gradient and temporalvariations of water quality in Daecheong Reservoir in relation to the major inflowingstreams from the watershed, during 2001~2010. For the study, we selected 7 mainstreamsites of the reservoir along the main axis of the reservoir, from the headwaterto the dam and 8 tributary streams. In-reservoir nutrients of TN and TP showed longitudinaldeclines from the headwater to the dam, which results in a distinct zonationof the riverine (Rz, M1~M3), transition (Tz, M4~M6), and lacustrine zone (Lz, M7) inwater quality, as shown in other foreign reservoirs. Chlorophyll-a (CHL) and BOD asan indicator of organic matter, were maximum in the Tz. Concentration of total phosphorus(TP) was the highest (8.52 mg L-1) on March in the Rz, and was the highest(165 μg L-1) in the Lz on July. Values of TN was the maximum (377 μg L-1) on Augustin the Rz, and was the highest (3.76 mg L-1) in the Lz on August. Ionic dilution wasevident during September~October, after the monsoon rain. The mean ratios of TN :TP, as an indicator of limiting factor, were 88, which indicates that nitrogen is asurplus for phytoplankton growth in this system. Nutrient analysis of inflowingstreams showed that major nutrient sources were headwater streams of T1~T2 andOckcheon-Stream of T5, and the most influential inflowing stream to the reservoirwas T5, which is located in the mid-reservoir, and is directly influenced by the wastewatertreatment plants. The key parameters, influenced by the monsoon rain, wereTP and suspended solids (SS). Empirical models of trophic variables indicated thatvariations of CHL in the Rz (R2=0.044, p=0.264) and Tz (R2=0.126, p=0.054) were notaccounted by TN, but were significant (p=0.032) in the Lz. The variation of the logtransformedIr-CHL was not accounted (R2=0.258, p=0.110) by Iw-TN of inflowingstreams, but was determined (R2=0.567, p=0.005) by Iw-TP of inflowing streams. Inother words, TP inputs from the inflowing streams were the major determinants onthe in-reservoir phytoplankton growth. Regression analysis of TN : TP suggested thatthe ratio was determined by P, rather than N. Overall, our data suggest that TP andsuspended solids, during the summer flood period, should be reduced from theeutrophication control and P-input from Ockcheon-Stream should be controlled forwater quality improvement.
