Information about the 65km long canalised River Baïse

Baise-location

The river Baïse, a left bank tributary of the Garonne, was restored to navigation in the 1990s over a distance of 65km, from its confluence with the Garonne at Saint-Léger to Camarade mill upstream of Valence-sur-Baïse. It was formerly navigable a further 21 km and 8 locks to the village of Saint-Jean-Poutge, a small river port serving Auch in the département of Gers. The Baïse is connected with the Canal de Garonne by a double staircase lock at Buzet-sur-Baïse, and with the navigable river Lot via a 5km length of the river Garonne (the ‘Garonne crossing’), downstream from the double outfall lock at Saint-Léger.

The navigation was abandoned in 1955 and sold to the riparians throughout most of its length, but the two départements Lot-et-Garonne and Gers invested more than €10 million in restoration of the waterway as the key to developing tourism in this rural area, redolent of armagnac and corn. The upstream limit of Valence was chosen because of the importance of the Cistercian abbey of Flaran, on the left bank of the river just before this small town is reached.
Baise-reg

History – The Baïse was naturally considered for possible canalisation by Henri IV, who resided in Nérac before he became king of France. It was a more regular, less challenging river than the nearby Gers. Napoleon also saw the value of canalising this left-bank tributary of the Garonne. The project was started in 1808, and completed a few years later. The waterway was closed in 1954 and removed from the list of navigable waterways in 1957, except for the section between the canal and the Garonne. It then became private property. Restoration works, after a study by the author in 1990-91, meant that the right to navigate had to be negotiated with the riparian owners. This popular waterway is operated by the Councils of the two départements.

Navigation

The Baïse is an ideal cruising river, with no particular difficulties except when the river is in flood. No vignette is required, as this is not part of the VNF network. The cruise on this tranquil shady river, steeped in history, offers a marked contrast with the long straight pounds of the Canal de Garonne. The river is attractively leafy and narrow, in some places twisting as well. In a suitable boat (including many hire boats available from
Buzet or Agen) it offers a uniquely delightful cruise, surrounded by wild life including lots of kingfishers (martin-pêcheurs). There are several attractive, historic small towns to visit. Navigation is interrupted when the Baïse floods to a level of +0.50m on the gauge at
Nérac. The speed limit is 6km/h.
The banks above Lavardac are all private and mooring must be at a locks or other pontoons, or the quaysides at Nérac, Moncrabeau, Condom and Valence.

Locks There are 21 locks including the double staircase at Graziac. Saint-Léger lock leading to the Garonne is 40.50m by 5.20m. It is extended by an additional chamber into the Garonne, since the sill of the original lock was too high to provide sufficient depth during periods of low flow on the Garonne. The route description gives the historic lock numbers, which started at Saint-Jean-Poutge, hence 29 for Saint-Léger and 9 for Flaran. The three locks up to Lavardac have the restricted dimensions of the original locks on the Midi canals: 32.00 by 5.20m. From here upstream, the locks are the same length but narrower (4.20m).
The lock-keeper posted at the Buzet locks from June to September issues the swipe card for operation of all locks, from 09:00 to 19:00, with the exception of Saint-Léger (access to the Garonne), and the double staircase lock at Graziac, which was not mechanised and is operated by a lock-keeper (9:00 to 18:00, with a lunch-break). The magnetic card may need to be ‘jiggled’ to get it to read, or in extremis the stop button may be given a quarter-turn to release it. Out of season, consult the canal staff or follow instructions posted at Buzet locks.

Draught The maximum authorised draught is 1.50m downstream of the junction with the Canal de Garonne, reduced to 1.20m upstream of the junction.

Headroom The bridges leave a minimum head­room of 3.50m above normal water level up to Nazareth lock, and 3.00m thereafter.

Towpath The towpath is of varying condition over the first 19 km up to Lavardac, and totally impracticable upstream from Lavardac following sale of the river to riparians between 1956 and 1962.
