authorized the president to have surveys made of routes for roads and canals "of national importance, in a commercial or military point of view, or necessary for the transportation of public mail." The President assigned responsibility for the surveys to the Corps of Engineers. To broaden the scope of possible improvements, Congress passed the first federal rivers and harbors legislation in May, again with the USACE charged to administer the work. New river and harbor legislation in 1826, authorized the president to have river surveys made to clean out and deepen selected waterways and to make various other river and harbor improvements. That year Congress also authorized the first survey for a canal between Atlantic Ocean and Gulf of Mexico,Timeline: Development of US Inland Waterways System
from Coosa-Alabama River Improvement Association, Inc. and expanded the Army engineers' workload. Although the 1824 act to improve the Mississippi and Ohio rivers is often called the first rivers and harbors legislation, the 1826 act was the first to combine authorizations for both surveys and the projects themselves, thereby establishing a pattern that continues to the present day.

Early legislation

Many of the early river and harbor legislation included authorizations for initial surveys of the navigation safety of rivers then used for transportation; as these were developed, authorizations for specific improvements were added. Many of these improvements were driven by the rapid growth in the use of steamboats on inland waters and the great commercial success of the

, railroads became recipients of federal funding; funding for river and harbor improvements increased sharply. The 1869 appropriations for rivers and harbors exceeded $2 million, and rapidly grew to tens of millions of dollars per year by the close of the 19th century; the Rivers and Harbors Acts between 1869 and 1930 are illustrative. Each of these acts identifies hundreds of projects to be built by the Secretary of War under the supervision of the Army Corps of Engineers.

This act begins the age of dam construction on the inland rivers. Prior to this act, all river improvements had been directed toward enhancing the existing channel by removing obstructions and redirecting flows with dikes or weirs. With this act, dams and locks began to be constructed that raised the level of the river in an effort to deepen the river for larger vessels and provide deep water during drought conditions.
