SO. DAKOTA RESEARCH TEAM: ALARMING INCREASE IN STOCK DAM SALTWATER DURING 2021 DROUGHT
Rapid City, SD - A team of research faculty and students at South Dakota Mines has been tracking salinity content in 70 stock dams across 12 watersheds in two northwestern South Dakota counties over the past two years. Their study, funded by the Bureau of Land Management, shows an alarming trend of increasing salinity in the stock dam water during the ongoing drought of 2021. In some cases, the salt concentrations of the water is high enough to cause adverse health effects for livestock and wildlife. In a handful of stock dams, the salinity is high enough to be lethal.
"We hope the information will help the people who matter the most, and that's the livestock producers in this scenario," says Lisa Kunza, Ph.D., associate professor of chemistry, biology, and health sciences at South Dakota Mines. "Our producers need decent water to give to their cattle and this trend could exacerbate the water shortages they are already facing. We hope our students can foster this collaborative effort to help local ranchers and land managers understand this problem, know their options, and find solutions."
