Lac de Coiselet is a vast 320-hectare reservoir in the Ain region offering excellent carp and catfish prospects across pristine, spacious banks—ideal if you want room to spread out and explore. Day fishing only, so you'll need to plan accordingly, though the sheer size means different swims perform at different times. Note: you'll need a day ticket from FD 01 (Ain federation) and must fish within their regulations; it's roughly 363 miles from Calais, making it a destination for a longer trip rather than a quick weekend.
Night fishing at Lac de Coiselet is authorised under Ain regulations. Night carp confirmed on 8 designated pegs, all on the right bank (rive droite), weekends only. Vegetable baits/boilies only. Bank fishing only. Immediate release — no keep-sack at night. Note: The lake spans both Ain and Jura departments. Night carp pegs are marked with on-site signage (though signs have reportedly been vandalised — exercise extra care to identify peg boundaries).
