The Watershed Alliance of Sandy Springs is holding a photo contest to try to raise visibility of the city’s six watersheds. Photos must be shot within the city’s boundaries and show images related to Nancy Creek, Long Island Creek, Heards Creek, Marsh Creek, Sullivan Creek or Crooked Creek.

A dozen winning photos will be selected for publication in a 2016 calendar. The calendar will be sold at the Sandy Springs Festival in September, the alliance said.

Entries are divided by age: photographers 10 and younger or 11 or older. Deadline for entries is July 31. Entries should be emailed to For more information:
