We were there at the end of June....if I remember correctly the shallow end is about 3 ft and the "deep" end is about 5 feet. Remember that community hall is right there- so the life vests are easily accessible if you need them. My kids (9,11,15,19) are old enough and good swimmers so we don't need to worry to much anymore (although they might drown each other!), but we often used the life vests for the younger 2 when we first starting going to BWV 10 years ago.
