Sun Valley Lake Waterfront Lot # 1982 for Sale. If you don't know about Sun Valley Lake its time you take a look. This is one of Iowa's best kept secrets! This 500+ acre lake has become one of the best fishing lakes in the Midwest. Light boat traffic make it a great family destination for skiing, kayaking and all things water sports. There is a 9 hole grass green golf course, tennis and basketball courts and a clubhouse with bar and great food. Association dues are minimal. Good roads surround the entire lake. The quiet atmosphere is a wonderful place to spend the weekends or for living year around. There are very few waterfront lots remaining on this lake.
