Teen's river rescue sparks Memorial Day water warning.

A teenager was rescued from the rushing waters of the Cosumnes River in Sacramento County after he and three friends went rafting and he was pulled downstream. The teen was not wearing a life jacket and was able to grab onto a tree to prevent getting pushed further down the rushing water. Rescue crews arrived and threw him a rope and a life jacket, and he was able to walk out of the water with only a few scratches. Officials have been warning people to stay out of waterways across the region due to the snowmelt, which is causing rushing currents, high water levels, and cold conditions. The teen warns others not to make the same mistake and to stay out of the water.
