You CANNOT Swim!Bicentennial Park
Went over there earlier today with my pup after reading about it here. Based on the picture for this park (the dogs playing in the water) I assumed swimming was okay and bee-lined straight for the water when we got there. Her leash kept getting tangled around fallen branches, so we only stayed in the water for 2-3 minutes before I decided we should find another spot to play in the water. When we went back to the main trail I noticed NO SWIMMING signs!! I'm not sure why you're not allowed to swim but i was afraid it might be because of pollution or toxic algae or something. We immediately went home and I gave her a thorough bath and washed her harness/leash. She seems fine but definitely keeping an eye out to see if she shows any symptoms of toxicity.
Besides this, the park was decent but more family/children oriented. Lots of playgrounds and a beach volleyball court and a tennis court. The paths through the woods around the lake were mostly paved with asphalt but completely flat and very short. Took maybe 10 minutes to do the loop.
