The Chairman of the Save Our Shannon Organisation is warning that gates must be opened further down the river to prevent flooding in this region.
The organisation was set up two years ago replacing the former Mid-Shannon Flood Relief Group.
The group says that while some flood defences have been put in place in the region, the fact is that farmers and rural homeowners are still on their own when it comes to trying to prevent flooding.
Michael Silke says a number of homes and farmyards will be under threat of flooding again in the coming days if action isn't taken now to release some of the water building up on the system.
"We're less than 2 feet below the massive surge we had on the 5th of January 2016 and we remember the consequences that had and the affect it had on people. The Shannon is currently over 6 feet above the navigation summer level. We're in a very very serious situation and we're appealing to all the different agencies to pull together and let as much water as they can go further down the river without affecting people".
