Mills
$800K damage
What happened
Drought conditions continued across North Texas. Although occasional rainfall helped some areas of North Texas improve by the end of October, many areas missed out on the beneficial rains. The U.S. Drought Monitor included more of the North Texas in the Extreme Drought (D3) category by the end of November than in the previous month, but did eliminate the Exceptional Drought (D4) area from North Texas.|Areas which did receive rainfall experienced reduced fire danger. Hydrologic deficits remained extremely high, with almost every lake well below conservation levels. The worst included Lake Bridgeport at over seventeen feet below normal, and Lake Grapevine at twelve feet below normal. Stage 1 water restrictions remained in effect in most metroplex counties. |The Drought Impact Reporter reported that hay prices in Texas were approximately twice what they were before the drought began this month. Crops continued to suffer, with the cotton production this year about half of last year���s crop.
