Water Resource Development Public Corporation project Regional development project Project that combines and in an economical and efficient manner.

	Incorporated Administrative Agency Japan Water Agency Project (The Lake Biwa Development Project) Lake leves Dreding of the South Lake Levees were constructed in low land districts around the lake to prevent flooding of Lake Biwa. The Seta River was dredged to increase its discharge capacity to facilitate water flow. Internal drainage facilities Improvement of the Seta River Weir Fourteen internal drainage facilities (drainage pumps and sluice gates) were constructed in six areas particularly vulnerable to flood damage in order to drain water from rice paddies and the like that have been inundated in a flood. To reduce the needless outflow of valuable water in droughts, the bypass aqueduct was constructed nearby the Seta River Weir to regulate discharge accurately even at low water levels.

	Public Corporation Project(The Lake Biwa Development Project) and Refinal Deveropment Project Rivers (A river related to the lake shore is contained.) Marine facilities To prevent flooding on bending rivers, high-bedded rivers and the like, engi-neering projects were undertaken to, among other things, raise embankments, dredge and dig riverbeds and widen rivers. To preserve Lake Biwa's valuable aquatic resource, ayu (Plecoglossus altivelis), artificial rivers were made at the mouths of the Ado and Ane rivers as spawning locations for when the lake's water levels have dropped. waterworks harbor, fishing ports The water intake facilities were relocated offshore and additional pumps were installed to ensure a sufficient amount of water even if water levels drop on Lake Biwa. The mooring wharfs were engineered and the waterways and docks, dredged to maintain the functions of harbor facilities and waterways even at low water levels.
