Be careful out on the water!

  • Always wear a safety vest when on the water.

  • Even calm rivers can present hazards, like high spring flows, dams, and other obstructions (downed trees can pose serious safety risks). 

  • In some rivers, high levels of bacteria and pathogens prevent safe swimming. Be sure to refer to postings by state agencies and local watershed organizations for information on related advisories. 

  • Watch for poison ivy alongside rivers, and always check for ticks after spending time in the woods! 

Do your research! 

  • Are you going to a coastal river? Check the tides so you don't end up stranded!

  • Both floods and droughts can inhibit safe boating. Check the weather and streamflow before you go!

  • Some watershed groups have up-to-date information on river conditions, such as flow levels on the Ipswich River, and river obstructions in the Sudbury-Assabet-Concord watersheds.

  • When in doubt, check with your local watershed or conservation organization for safe paddling spots and where to park.
