Tuesday 4 June 2013 the IFS stocked 300 adult brown trout fresh from the spawning run at Liawenee into the River Leven. The fish were released at Bannons Park on the Gunns Plains Road. A good turnout of anglers witnessed the release. These fish have yet to spawn and could provide a boost to natural recruitment in the river. The River Leven like many other rivers throughout the state has been hit hard by the large number of cormorants that were present during the 2012/13 season.
