  • Although Otoe County is not officially included on drought maps by July 10, several trees are seen in the city losing their leaves.
    Shallow-rooted trees, such as maple, hackberry, cottonwood and birch, are first to show signs of dropping their leaves in a process called abscission.
    It is considered a defense mechanism for the tree. A large tree can soak up 100 gallons of water a day, but water escapes through green leaves, so trees may shed their leaves to conserve water.
    The U.S. Drought Monitor map from the National Drought Mitigation Center at the University of Nebraska-Lincoln lists southeast Nebraska as abnormally dry. On June 12, two-thirds of Kansas and the edge of Nebraska near Falls City was listed as in moderate drought.
    On July 5, half of the United States was listed in moderate drought and an extensive heat wave was reported for the Midwest and MidAtlantic.
    The center reported that the lower 48 states had a record percentage of land, 55.96 percent, in the drought area.
    The record is from the 12-year-old Drought Monitor. In 1934, extreme drought was recorded from Nevada to Indiana and from North Dakota to Kansas.
    A high temperature of 86 degrees in Nebraska City on Tuesday was cooler. The Nemaha County Herald reports 11 days in June at 90 degrees or higher.
    In 1934, 82 days were recorded with a temperature of 90 degrees or higher.
    For the week ending July 8, temperatures on southeast Nebraska were considered 6 degrees above normal.
    Southeast Nebraska has received 10 inches of rain since April 1, two inches below the normal of 12 inches.
    Most of the June rainfall came June 15-16, where up to four inches fell.
    A rain event of 4.8 inches was reported in Rulo and Richardson County on July 8. Farms around Falls City reported 1.5 inches.
