Lots of lakes have good bites right now. Bitter, Waubay, and Poinsett are getting the heaviest pressure, along with a slough or two, but I’ve seen nothing from bitter or waubay that would make me want to start with either of those lakes. There are so many lakes a guy can pick and find fish on, why go to where the crowds are?
Also, be mindful that there are closures of water over private land starting to occur. 10 lakes/sloughs with partial or complete closures, and more on deck. you can find that information on the map here, and more information at the GFP website.
