There are many factors that enter into the determination of when dusk is. The Recreation Department's greatest concern is for the safety of the general public. Other considerations that are weighed in the decision are as follows: The amount of natural light available, The clarity of the water, Local weather conditions, The size of the swimming crowd This makes it very difficult to pinpoint a specific time each evening
Season Closing
Will be announced at a later date based on water conditions and staff availability
