State water officials are asking towns and industry along the North Platte River to assess their water rights and whether they might have to tap into an emergency water bank.
For now, those with "junior" rights must shut off their spigots, with little snow and water relief in the forecast.

I coped with 2025 by reading and running. I read 52 books, mostly fiction. 34 new to me, 18 comfort rereads. I also ran 1,200 miles, including 2 50km races and a 43 mile fun run along Lake Superior at Pictured Rocks.
