''Ahquabi'' means "resting place" in the Fox language. The park is south of Indianola and south of Des Moines. ==History== The area was recommended for a state park site by J.N. "Ding" Darling and in 1935 the Civilian Conservation Corps constructed the dam and reservoir. However methods at the time did not consider long-term effects of the surrounding watershed. By the 1980s sedimentation had shrunk the reservoir by and agricultural pollutants in surface runoff had reduced the water quality. Various government and community organizations began working with neighboring landowners to improve Lake Ahquabi. Widespread adoption of soil conservation practices by local farmers and the development of buffer wetlands and sedimentation basins have halved the amount of sediments and nutrients reaching the lake. In the mid-1990s the lake was extensively dredged, the shoreline stabilized, the dam improved, and an aeration device installed. Game fish like largemouth bass, bluegill, sunfish, channel catfish, and crappie were stocked. After restoration Lake Ahquabi State Park's annual visitation and fishing use each increased three-fold.〔 Anglers have been catching an average of 2.7 fish per hour, twice the catch rate of most Iowa lakes.〔 It has been estimated that the money brought into the local economy by increased visitation equalled the $4 million spent on the restoration project within 2 years. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lake Ahquabi State Park」の詳細全文を読む スポンサード リンク
