Earlier this month I went back to Iowa to see my family and grandparents. While there my father and I fished Green Castle Lake. I remember fishing this while in High School, it was completely grown over and you couldn't fish at all. In the years since, it looks as though they have added some Grass Carp and really managed the lake well. The state record Crappie at 4 lb came out of their and they list Northern Pike in the special regulations. We didn't catch either of those species but we did land a few small largemouth. We saw some 5 lb + fish but they were in spawn and no matter what we threw at them they were not interested. Overall it has become a beautiful lake, a promising fishery, and more than anything else it was great to be able to fish with my father.
