Enjoy the parks.
Know the rules. 

Keep a lid on your ice chest. 
Be sure to securely latch the lid both in the parks and on the river. Loose lids can cause your contents to spill and float downstream - ruining your day and the river too.

Keep a lid on your alcohol. Consumption and public display of alcohol prohibited in all city parks. There are alcohol access points to the river though so you may still take refreshments on your water activities.

Keep a lid on your litter. 
Please dispose of trash properly. Recycling receptacles and trash cans are located throughout the park to make it easy. Remember, if you take it in the river, bring it back out again.

Keep your styrofoam at home.
All styrofoam is prohibited in the parks and on the river. This includes not only ice chests but cups, plates, toys and floats too. Please use paper products or recyclable plastics for your picnic.

Keep pop-up shelter and propane grill next to City picnic table only.
Pop-up shelters and propane grills are limited to one each per city installed picnic table. Charcoal or wood grills are not allowed in any park. Personal tables are also prohibited.
