Locks
The Mayenne river was naturally navigable between Angers and Château-Gontier but canalisation of the river and the construction of locks has greatly improved navigation conditions over time. There are 37 locks between Mayenne and Laval and 8 between Laval and the point where the Mayenne river joins with the Sarthe to form the River Maine.
The locks provide magnificent panoramic views, and some of them are well known for the activities that take place there or for their abundance of flowers.
- Le Pendu, a lock in bloom
- Neuville – a lock with a crêperie
- Benâtre – a lock with a restaurant
- Entrammes River Stopover  at Port Rhingeard – snacks, exhibitions, shows from May to October, boatyard.
- Bonne, a lock in bloom
- La Fourmondière lower lock – La Guinguette restaurant, a former lock-keeper’s house, providing some very tasty dishes
- La Fourmondière upper lock – Eclus’epos: art exhibitions
- Montgiroux lock – river halt
- Grenoux, a lock in bloom

Hydroelectric micro-generators
Production of renewable energy is an ever more pressing issue.
There are 24 hydroelectric micro-generators along the Mayenne, 17 of them managed by EDF.
The most recent of them, such as the one at the Roche Mill near Commer, have a turbine that can work with very small flows of water.
The electricity they produce is enough to power the equivalent of about 40 homes and they're designed to give maximum protection to fish stocks, especially eels.
