To provide a field water storage system that enables water to be stored in a filed with efficiency.SOLUTION: A field water storage system 10 has a water management server 28 that can control a water supply device 31 and a drainage device 33 for managing water supply and drainage in a field H. As control modes for controlling the water supply device 31 and the drainage device 33, the water management server 28 has a normal mode for adjusting the drainage height of the field H according to predetermined conditions, and a dam mode in which the drainage height of the field H is set to "dam-preparation-time drainage height" regardless of the predetermined conditions and water is drained from the field H once, before the drainage height of the field H is set to "dam-storage-time drainage height" higher than the drainage height in the normal mode", to enable a larger amount of water than that in the normal mode to be stored in the field H. On the basis of a predetermined first reference, "dam-preparation-time drainage height" is automatically set.SELECTED DRAWING: Figure 2 【課題】圃場に水を効果的に貯留することが可能な圃場貯水システムを提供する。【解決手段】圃場Ｈの給排水を管理する給水装置３１及び排水装置３３を制御することが可能な用水管理サーバ２８を具備する圃場貯水システム１０であって、用水管理サーバ２８は、給水装置３１及び排水装置３３を制御するための制御モードとして、所定の条件に応じて圃場Ｈの排水高さを調節する通常モードと、所定の条件にかかわらず、圃場Ｈの排水高さを「ダム準備時排水高」に設定して圃場Ｈの水を一旦排水した後で、圃場Ｈの排水高さを通常モードにおける排水高さよりも高い「ダム貯留時排水高」に設定することにより、通常モードよりも多量の水を圃場Ｈに貯留可能とするダムモードと、を具備し、所定の第一基準に基づいて「ダム準備時排水高」を自動的に設定する。【選択図】図２
