1 IRRIGATION TALK — Jay Antle, executive director of the Center for Sustainability at Johnson County Community College, was to speak 7 p.m. Thursday at Neosho County Community College, 900 E. Logan St., Ottawa, on water irrigation in Kansas. “From ditches in Garden City, to center pivot units across the state, to new plans to divert Missouri River water to Goodland, this presentation will encourage Kansans to consider how the past can inform present-day discussions of water usage in the state,” according to the event’s Facebook page. According to a press release, the discussion is offered in conjunction with the Old Depot Museum’s current exhibit, “Crossings: Getting Over, Around, and Through Water in Franklin County.”
