Biwako canal in Kyoto City was constructed in the period from 1885 to 1890 in order to supply water for irrigation systems and develop the utilization of water power, transportation by ship and so on. There were 2 routes on the canal, the one was the route in Ohtoh area beside eastern district of Kamo river for the transportation and later also for hydroelectric power, the other was the route of north-east area of Kyoto for the irrigation. The expropriation performance of the canal was discussed in this paper depended on the maps drawn in the construction and the cadastre on expropriation. The new city planning in the Ohtoh area, especially road networks along the canal was designed, and the canal route was determined to decrease flow rate and to choose the low cost expropriation.
