Between 2000 and 2010, the Missouri River was the driest it has been in 1,200 years, according to a study published Monday.
The study showed that rising temperatures linked to climate change was the cause. The higher temperatures reduced snowfall in the rocky mountains, resulting in reduced runoff into the Missouri River basin. Researchers involved with “The Turn-Of-The-Century Drought Study” studied instrumental data on water levels collected over the last 100 years but had to rely on tree rings to give them an idea of when droughts occurred and how severe they were over previous centuries. This study concluded that the Missouri River has not been that low since a single drought event in the 13th century.
Continued droughts could be disastrous for farmers in the Midwest who rely on the Missouri River for crop irrigation and municipalities that use it as a fresh water source. Species of freshwater fish and waterfowl, tourism industries, and hydropower production along the Missouri River could also be negatively impacted, according to a Washington Post article.
This study only focussed on the years between 2000 and 2010, but data from more recent years shows that droughts in the Midwest are likely to increase in frequency and severity in coming years due to climate change.
