The minimum flow of the ohyama river changes seasonally. At present time, from 21th March to 30th September, the minimum flow is 4.5 m3/s, and that is 1.8 m3/s from 1st October to 20th March. The minimum flow is 1.5 m3/s before. The effect of the minimum flow on the physical situations, for example, water width, water depth and flow velocity, are studied by using an numerical simulation. Furthermore, a physical habitation for an ayu also is estimated by using the PHABSIM. It is conformed that the increase of the minimum flow gives good physical situation to ayus.
