At today’s 2 p.m. meeting of the Helix Water District Board (7811 University Ave., La Mesa), directors will consider addition of fees and other changes at Lake Jennings, including adding kayak rentals and a tee-pee rental venue at the campground.  These are the latest improvements proposed by a committee led by director Joel Scalzitti.    As a result, the lake that some board  members sought to close due to budget shortfalls is now operating at a profit.
