Volunteers from The Grantham Canal Society took delivery of the boat at the Earlesfield Bridge stretch in Grantham on Wednesday (11 July).
It will be used to help society members clear away rubbish dumped in the waterway.
Cabinet Member for Environment, Cllr Dr Peter Moseley, said: "The Canal Society does a lot of valuable work to maintain the canal and keep it up to scratch as an asset for the town and the district.
"Sadly, parts of it have become something of a dumping ground for litter, but the gifting of this boat will help the volunteers keep it clean and tidy so it can continue to be a haven for wildlife."
Canal Society Chief Executive David Lyneham-Brown said: "This boat will make a real difference to our work, which will continue through the summer. In the past we've used grappling irons, rods and poles to try to clear hard-to-reach places and get down to the canal bed. We will now be able to access those areas we couldn't before."
The canal originally ran into the centre of Grantham, ending at the wharf behind what is now Homebase. It linked Grantham to Nottingham and beyond to the rest of the country via the extensive national system of waterways.
Canal Society Head Ranger, Christopher Cobb, said: "Our ambitions for the canal don't stop where it meets the A1. We're looking to clear the whole canal but we are concentrating on this stretch first.
"While the water is low, it's a great opportunity to get to what's at the bottom.
The Society's long term campaign will ultimately see the canal restored, re-opened and back in use along its entire length.
