Saylorville Lake is a reservoir on the Des Moines River in Iowa. It is located upstream from the city of Des Moines, and from the mouth of the Des Moines River at the Mississippi River. It was constructed as part of a flood control system for the Des Moines River as well as to aid in controlling flood crests on the Mississippi, of which the Des Moines is a tributary. At its normal level of above sea level, Saylorville Lake covers an area of or and reaches some upstream. At full flood stage the lake can reach or and reach long. At this point any further flow into the lake is channelled over an emergency spillway to the west of the main dam structure. The record high stage for the reservoir was above sea level set on July 11, 1993 during the Great Flood of 1993. Construction of the Saylorville Dam was authorized by Congress in 1958. Excavation began at the site in July 1965, becoming fully operational in September 1977. The dam itself is long, tall, and wide at the top. The lake is utilized for many recreational activities in the central Iowa area as well, as there is a large state park infrastructure surrounding the area of the lake, notably Jester Park and Big Creek State Park. Boating and swimming are very popular here, as are camping, deer and game bird hunting, fishing, hiking, biking and disc golf. Coast Guard Auxiliary (Flotilla 4 ) provides boating safety education and free vessel safety checks to boaters in the area. Fish species that can be found in the lake include crappie, bluegill, green sunfish, largemouth bass, smallmouth bass, brown trout, northern pike, common carp, white bass, walleye, yellow bass, american eel, flathead catfish, channel catfish, bullheads, and hybrid striped bass == External links == * (Corps of Engineers' Saylorville site ) * (Mississippi Valley river levels ) * * (Local Coast Guard Auxiliary Flotilla 4 ) 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「Saylorville Lake」の詳細全文を読む スポンサード リンク
