Help us find Travis Valenti

Travis Valenti, had a kayaking accident on Fri in Washington State at Lake Crescent & presumed deceased. Unfortunately, park rangers searched but don't have a dive team to search further. If you have anyone that you know of who can HELP us in the SEARCH/RECOVERY, we'd greatly appreciate it. We need to be able to find him & bring him home. The family is obviously distraught & want their son's body back in NY. Any agency/resources/info is greatly appreciated. Thank you kindly!
