Jamestown is a small village on the west bank of the River Shannon in south County Leitrim, roughly 5 km east-south-east of Carrick-on-Shannon.

It serves as a notable access point on the Upper Shannon, with its own quay that makes it a popular stopping place for cruisers and recreational boaters.

Navigation downstream for cruisers is not possible beyond Jamestown; vessels must use the Jamestown Canal and Albert Lock, which rejoins the Shannon south of Drumsna. The weir at Jamestown is a well-known paddling and angling spot.

Kayakers should be aware that water below the feature can be shallow, eddy lines are boily, and rolling conditions can be challenging.

Anglers will find productive swims on both the upstream and downstream sides of the weir, with bream, roach, hybrids, and wild brown trout all present. Access to the riverbank is partly through private land via stiles provided by Inland Fisheries Ireland.

Paddlers are encouraged to respect the local community, as access to the site depends on good relations with residents.
