After that farmers will be allowed to use the water for farming.
But after five days of water release, the water flow has only extended 60km up the canal.
According to a survey by authorities, many pumping machines were used to drain water from the canal to feed plantations along the route.
An inspection found farmers had installed more than 10 water pumps close to Klong Makham Thao to drain water off to Klong 14 in tambon Nongsalai to be used for vegetable farming and feeding livestock.
Military officers said they had asked farmers for their cooperation in not draining the water in Klong Makham Thao, but many farmers did not listen.
As a result, the officers are prepared to exercise tough measures by seizing pumping machines if farmers still failed to follow regulations, a military source said.
They could reclaim their water pumps from authorities after Friday when the water releases end, he said.
