This summer is the perfect time to try casting a line in Storm Lake during Iowa's Free Fishing Weekend, June 5-7. During this time frame, Iowa residents can try fishing without buying a license on June 5, 6 and 7 as part of the Iowa Department of Natural Resources’ (DNR) free fishing weekend. All other regulations remain in place. This weekend is the perfect opportunity for families, kids, grandparents, and first time anglers to get outside and enjoy the water together. Wheth
