Ballyquirke Lough, between Bushpark & Moycullen, 8km (5 mile) North East of Galway City out the Cliften/Oughterard road.
Boy was this a find!! Myself and my mate thought it was just an angling lake but she had said, I hear there's a canal that links it to the Corrib. I thought she meant the overgrown one at the south of the lake but no.... if you paddle up about a mile mile (2km??) you'll come across the entrance to the canal, with a concrete traffic bridge over it....
There seems to be no current and it's over 5 meters (15 ft) wide, plenty of room for two kayaks. It's very peaceful with waterlilies, kingfishers...... It runs for about a mile and you come out at lough Corrib. Alas, lough Corrib the exit (or entrance) is over grown with reeds so I didn't chance paddling out to the lake this time because visibility was bad and I didn't know if I'd be able to find my way back to the entrance of the canal that end, however, the canal itself was wonderful. Next time I should bring a ball of red wool
There's another canal to the right, about half a mile down, which we didn't paddle but it seems to lead to a drain after about 1/2 a mile, we'll paddle it next time.
I posted some pictures on Face book
