My oldest son won our hatchery lottery this year so he got to take me, his two brother's and his grandfather fishing at our rainbow trout hatchery in Castalia. Our fishing slot was from 11:10 am till three and we had a beautiful small crystal clear creek loaded with hungry trout all to ourselves. The rules are catch and keep with a 5 fish limit per person. You are not allowed to throw any back. Being a hatchery loaded with fish hooking up wasn't really an issue but keeping them on with three kids 5, 7 and 9 was a challenge that kept the adults running back and fourth. We stuck to fly fishing only and all three did pretty well casting but most of the fish were large enough that we had to keep one hand on the rod and one on the back of their shirts to keep them both from going in. We finished the day with 22 trout most of which were in the 14-16 range and couple 19"-20". My 5 year old had a couple of bigger ones on that we just couldn't land. Afterwards we spent a few hours cleaning and filleting the trout and had a nice grill out with my wife's family. It was a great day to spend with my kids.
