http://nationalmap.gov/hydro.html

This map shows water bodies and water ways along the Missouri River. It is important for water management as well as district planning. Water can be a vary valuable resource and asset to the land since for development to prevail there must be water available, thus this map can be extremely variable and when using it for mapping property it is of utter importance that it is accurate because little changes to the map can have large impacts when applicable to real life. There is more data on surface water in the US from USGs in the National Hydrography Dataset (NHD). The NHD has data covering all streams and lakes with a scale of 1:24,000 and 1:100,000 which provides a network helpful for the analysis of any type of movement of surface waters, whether it be due to navigation, erosion, sediment transport, or effluent dispersion as some examples.
