How Is the River Changed by Lock Closure?

A Sip of Science, held the second Wednesday of each month, will meet Wednesday, May 11, 5:30-7 p.m., at Aster Cafe, 125 Main St. SE, and will focus on “How Is the River Changed by Lock Closure?” The Minneapolis Riverfront Partnership will present what they have learned in an LCCMR-funded study about how the river has changed as a result of the closure in early 2015 of the Upper St. Anthony Falls Lock. This science happy hour is sponsored by the National Center for Earth-surface Dynamics. For more information or to RSVP, visit www.nced.umn.edu/community/sip-science.
