This has been exacerbated by human activities such as draining wetlands that naturally store large amounts of water and building paved surfaces that do not absorb any water. [12] Water then runs off the land in quantities that cannot be carried within stream channels or retained in natural ponds, lakes, and human-made reservoirs .
The pre-development Missouri River as documented by Lewis and Clark was considerably different from today's river. The historic Missouri was a broad, slow-moving, shallow river with braided channels. These past river conditions created a haven for wildlife, which included vast floodplain forests of giant trees, marshes, and even wet prairies ...
A wetland (aerial view) Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
The Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) is a 1990 United States federal law that provides funds for wetland enhancement. [1] The law is implemented by federal and state agencies, focusing on restoration of lost wetlands of the Gulf Coast , as well as protecting the wetlands from future deterioration.
Where a wetland is described as "manipulated", this might mean that it has been drained, dredged, filled, levelled, or altered in some other way to allow agriculture or development to take place on the site. [8] If manipulation of wetlands results in unavoidable adverse impacts, compensatory mitigation measures are used to offset these impacts.

Many early critics of the Pick-Sloan plan were in favor of creating a Missouri Valley Authority (MVA). They claimed that the MVA would provide a more unified solution to water development on the Missouri River than the merged ideas of opposing bureaucracies. Ideas for the MVA were influenced by the success of the Tennessee Valley Authority.
