The Rangers out at Lake Red Rock offer some reminders to help you return home alive this weekend. Statistics show that 90 percent of those who drown at U.S. Army Corps of Engineers lakes and rivers may have survived if they had worn a life jacket. Swimming in open water is more difficult than in a swimming pool, because you can tire more quickly and get into trouble. It only takes 20 seconds for a child to drown, and several people drown each year within 10 feet of safety because the people around them did not recognize that they were drowning. Seconds count, and it could make the difference between life and death. The U.S. Army Corps of Engineers is the Nation’s largest provider of outdoor recreation, managing more than 420 lake and river projects in 43 states.
