The news comes just weeks after the Coalition Government axed the funding for the free swimming programme - aimed at under 16's and over 65's.
Leader of the Council, Cllr. Burt Keimach, Conservative (Market Rasen Ward), said:
"At the moment we are the only council in Lincolnshire, who have made a commitment to go down this route.
"We have taken the decision after careful consideration and believe we have made the right decision for the local community.
"In May, more than three thousand people accessed the free service in West Lindsey, helping to keep them occupied and lead a healthier lifestyle.Figures show that in May, 2,114 under 16 year-old and 902 people over the age of 60 accessed the service.
"As a council we are delighted to be able to continue to provide the service especially through-out the summer holidays until the end of August."
Mr. Dick Holmes a spokesman for Lincolnshire Police said:
"We fully support the continuation of this initiative. The police service in general works hard to provide diverse activities for children and young people particularly through the summer holidays. The fact West Lindsey District Council is keeping the free swimming throughout the summer can only assist us with that."To be eligible for free swimming applicants need to register at the leisure centre and provide proof of age, either with a birth certificate or a bus pass.
