(AP) – Unusually heavy summer rainfalls have swollen rivers and creeks all over Tennessee and the surrounding area, making many normally placid areas dangerous for outdoor recreation.In Middle Tennessee, over the past holiday weekend, 6 to 10 inches of rain fell east of Nashville to the Cumberland Plateau, falling on ground that already was saturated. In East Tennessee, the National Weather Service has recorded record rainfall so far this year in Chattanooga, Knoxville and the Tri-cities area.The heavy rain has led to several river rescues. Four people were pulled from the Barren Fork River in Warren County after kayaking mishaps last Sunday.In Murfreesboro, four 911 calls in four days from the same area of the Stones River in Murfreesboro have not kept away swimmers looking for a pretty spot to cool down.
