The U.S. inland river system is approaching historic levels of low water at the critical harvest time. Comparisons are being raised to the previous historic low water levels of 2012 and even 1988. River gauges are not at 1988 levels yet but could be by October 26 if rain relief is not forthcoming, according to projections.The St. Louis gauge is at -2.4 feet below the reference plane and projected to reach -3.1 by October 26. Memphis stands at -8.65, projected to reach -9.4 by October 26. Cairo is at 7.26, versus a projected 6.8 by October 26. By comparison, Cairo reached 7.15 during the 2012 low-water event and 4.93 in 1988. Even more dire levels could be reached when the Missouri River flow from Gavins Point is cut off in November. |
