摘要： PROBLEM TO BE SOLVED: To provide a water level controller which allows irrigation water to be quickly supplied to or discharged from a paddy field, and is easily cleaned to remove mud, sand or the like which builds up in the device. SOLUTION: This water level controller is for an irrigation water supply/ discharge system for a paddy field, wherein water flowing into a lower chamber 11b of a water supply/discharge measure body 11 via a water supply section 15 moves into a controlling section 11g in an upper chamber 11a via an opening provided in a partition plate 12 in the water supply/discharge measure body 11, and then into a communication tube 11f leading to the paddy field via a water supply hole 18a in a third partition wall 18. Water is then supplied from the communication tube 11f to each farming section in the paddy field via a water supply/discharge tube 19. Water in the farming section flows downward, via a water level controlling tube 22, into a water discharge section in the lower chamber 11b in the water supply/discharge measure body 11, when its level exceeds the upper side of the water level controlling tube 22, being discharged out of the water supply/discharge measure body 11 via a water discharge tube section 16.
