Reed growth was observed at an experimental field located in the eastern shore of Lake Biwa's South Basin from December 1997 to October 1999. This study aims to investigate effects of water depth and ground level change on reed growth. In the results, findings are as follows: (1) Average density of reed shoots in the autumn of the second year after planting was 94.0, 72.8, 51.8 and 31.6 shoots·m<sup>-2</sup>, respectively for Mat Method, Pot Method, Sand Bag Method and Big Stump Method. (2) Reeds were able to sprout very well on the ground higher than -30cm of the Lake Biwa standard water level (B.S.L.). On the ground lower than B.S.L. -30cm, reeds planted with Mat Method produced the highest density of feed shoots among all of the methods applied. (3) Correlation analysis between water level and increase rate of reed density showed that deeper water levels (about 30cm for the first year, about 40cm for the second year) tend to inhibit reed growth, but that submerged conditions less than 30cm promote that compared with dry condition.
