Competitive swimmers have been assured by the Town of Hawkesbury that any temporary closure of the indoor pool at the Robert-Hartley Sports Complex will be planned so as not to interfere with their programs. The Orca club, which has about 60 swimmers, feared a closure from April to September for dehumidification and water chemistry work. The administration acknowledges a lack of communication and specifies that the work, estimated at $500,000, is necessary for security and infrastructure reasons.
