That sound of that small creek I heard was because it's about 4 feet deep now (usually about 6 inches). Also, I have a new waterfall and creek running down the mountain I live on, about 20 feet from my house and three feet from my firepit. It's about 2 feet wide, 6 inches deep and moving fast. Never ever been water there before. My garage has inch of standing water in it. Fun fun!
