It's back! A special day for our canine friends! Please join us for an end-of-summer celebration at Arlington Reservoir with your four-legged friend for some canine-only swimming on Sunday, August 23 from 12-2pm.

All dogs must be licensed, vaccinated and healthy.  Bathrooms and Snack Bar will be open.  Only dogs are allowed in the water.  (The water will no longer be treated and therefore unsafe for general public bathing.)  Donations Welcomed!

  • Dogs must be 4 months old to participate.
  • Dogs in heat not allowed off-leash.
  • Clean up after your dog!
  • Please keep your dog leashed entering or exiting the Reservoir Beach gate.  Off-leash permitted inside the gates provided they are on strict voice control.
  • Aggressive dogs are not permitted off-leash.  Dogs that show continued aggression towards people, other dogs or wildlife must be removed immediately.
