  Major flooding occurred in Vienna, where numerous businesses were flooded. A car dealership and another business had 2 to 3 feet of water inside. Local residents reported that flooding in Vienna was the worst since 1973. A number of residences around the county were flooded. Route 37 south of West Vienna was impassable, with water up to the headlights of vehicles. Flooding of the Cache River closed a large section of Illinois Route 37 for days. Railroad tracks were washed out near Belknap. Due to damaged tracks, a train derailed north of Vienna. The engineer and conductor were injured when two locomotives tipped on their side. Sections of U.S. Highway 45 and Route 37 were damaged by floodwater rushing across them. Most of the damage was erosion of shoulders. Farmers lost some animals and equipment to the flooding. Water rose over bridges, and at least three vehicles were carried away by floodwaters. Numerous roads were closed, including the most vital routes: U.S. Highway 45, Route 146, and Route 37.

• Drought09/01/2007

  Johnson

  $3.5M damage

  What happened

  Severe drought conditions that developed late in August persisted through September. The persistent 500 mb high over the southeast and south central U.S. started to break down at times, allowing an increase in rainfall. At Carbondale, the monthly rainfall was 2.19 inches. This rainfall was beneficial but not sufficient to improve drought conditions. Soil moisture in the top 12 inches of soil was running 20 to 50 percent below normal. This impacted the agricultural sector. Statewide across Illinois, 55 percent of pasture land was rated poor or very poor. The soybean crop sustained over 60 million dollars in losses in southern Illinois alone. Fire danger remained high for part of the month. A ban on outdoor burning was posted in Union and Hardin Counties for part of the month.
