June runoff in the Upper Missouri River Basin was only 52% of average this year, so the U.S. Army Corps of Engineers is implementing water conservation measures on the dams it manages along the stream. The changes come as the basin saw runoff peak several weeks earlier than normal. Above Fort Peck, the snowpack hit only 86% of average in late March. Based on its forecasting runoff for the year may be only 60% of average which would make it the 10th driest year in the basin since 1898. Meanwhile, parts of the lower basin have received heavy rainfall.
