Green Castle Recreation Area
In 1977 Marshall County Conservation Board purchased a 116 1/2 acres area with a 16 acre lake now know as Green Castle Recreational Area. The rolling landscape of this area is painted with native prairie, evergreen trees, and hardwood trees. Green Castle has many day use facilities to offer including: three shelter houses (one reservable by contacting 641-752-5490), hiking trails, astronomy observatory, and a small wildlife exhibit.
The lake was renovated in 2014, accumulated silt
was removed, the shoreline armored with rip rap and numerous additional fish
habitat structure created. The lake was restocked with bluegill, large-mouth bass, channel catfish and black crappie. This fishery will improve over the
next few years. Several new fishing jetties were also constructed in 2014 as
well as a boat ramp installed near the south end of the lake for easy access
for canoes and kayaks.
When you visit make sure that you also stop by the wildlife exhibit to see the bison and swans and check out the Central Iowa Astronomy Club to see when their next astronomy event will be held at Green Castle Recreation Area.
