Agricultural reservoir is typical water resources with streams and irrigation canal in Gyeonggi Province. Its Water Quality(WQ) as well as basin information is not readily available and kept for further review.
This study aimed to collect and analyze the existing data to classify major types according to its WQ. Only 1/7 of reservoirs in the province have been surveyed for WQ, and the rest not been monitored at all or sporadically checked. Based on the existing records, 50% is maintaining its WQ, and 25% improving, 25% deteriorating. Oligotrophic and mesotrophic reservoirs are on the decrease, and eutrophication aggravated in many cases. COD is getting better recently, TN & TP is steadily worsening. COD is relatively higher from April to July, just when irrigation begin than the rest of the year, and Chl-a exceeds its standard for agricultural use from April to September. All reservoir exceed TN standard. The WQ of many reservoirs are susceptible to urban land use.
Based on its WQ and pollution sources, this study suggests type-classification for policy decision making. If current WQ exceeds legal standard with deteriorated tendency, the highest priority is given.
Among the highest class, higher urban land use ratio weighted more than the other land use pattern and pollution sources. Five among 365 reservoirs, Dongbang, Aecheon, Myeokwoo, Hyochon, Giheung, in the province are selected as the priority management targets.
The use of agricultural reservoir became more diversified into tourism and leisure besides agricultural water supply. To explore the WQ improvement, monitoring is essential, so related regulations need to expand into smaller scale than the present. Basic and comprehensive format to keep the data for each reservoir is also suggested for local working group. Compiling reservoir cyclopedia can be the practical step to organize scattering data in many institution and sources. Reservoir Cyclopedia is useful and practical information as internet- or mobile-based web data. Local government structure are also need to integrated for control means in policy procedure. Operating administrative collaboration team to organize the decision making process in Gyeonggi Province can be a primary alternative option. Bearing the expenses for WQ maintenance by applying user pay principle should be considered also in near future.
