Meelick weir lies downstream of Banagher, and regulates the river level for Victoria Lock; the first lock on the Shannon navigation upstream of Lough Derg.
The only rapids and alluvial woodland – in the entire middle reaches of the River Shannon – occur downstream of this weir. Even here you do not experience the full flow of the river, as much of the flow is diverted away from here via the “new cut”. The river channel downstream of the weir was dredged and heavily modified during Victorian times; however this is still a very wild place.
If you ever want to get an appreciation of what the Old River Shannon may have looked like before the Shannon scheme, then go here.
