The Roscommon County Council filed the planning application in September. A temporary pipeline will drain water from Lough Funshinagh and release it into the nearby Cross River as part of the relief efforts.

Until long-term steps to control the region's flood risk are finished, temporary measures are being implemented. The planning application is subject to certain conditions.

Last winter, the south Roscommon lake reached an all-time high. Some homes had to be evacuated as a result, and many more needed to rely on industrial pumps constantly to stay dry.

Simon Harris, the Taoiseach, has praised the ruling. "I have met with a number of residents who have been affected by the flooding at Lough Funshinagh and saw first-hand the situation homeowners were dealing with," he stated.

"I want to thank OPW Minister Kieran O'Donnell, his Officials and Roscommon County Council for driving forward in finding a solution for the families involved," he said.

According to Roscommon County Council Director of Services Mark Keaveney, the ruling opens the door for the local government to offer much-needed assistance to nearby estates impacted by flooding.

The council will keep working towards an application for a permanent solution to solve the numerous issues surrounding Lough Funshinagh, he added, acknowledging the dedication and support of everyone who worked on the proposal.

Installing a 3 km subterranean overflow conduit from Lough Funshinagh to the River Shannon is the long-term fix.
