The U.S. Senate Appropriations Subcommittee on Energy and Water Development is one of twelve subcommittees of the U.S. Senate Committee on Appropriations. The United States Senate Committee on Appropriations has joint jurisdiction with the United States House Committee on Appropriations over all appropriations bills in the United States Congress. This is called "302(b) allocations" after section 302(b) of the Congressional Budget Act of 1974. That amount is separated into smaller amounts for each of the twelve Subcommittees. The federal budget does not become law and is not signed by the President. Instead, it is guide for the House and the Senate in making appropriations and tax decisions. Regular appropriations bills are passed annually, with the funding they provide covering one fiscal year. The fiscal year is the accounting period of the federal government, which runs from October 1 to September 30 of the following year.

There are three types of appropriations bills: regular appropriations bills, continuing resolutions, and supplemental appropriations bills. If Congress has not enacted the regular appropriations bills by the time, it can pass a continuing resolution, which continues the pre-existing appropriations at the same levels as the previous fiscal year (or with minor modifications) for a set amount of time.

Appropriations bills are one part of a larger United States budget and spending process. They are preceded in that process by the president's budget proposal, congressional budget resolutions, and the 302(b) allocation. Article One of the United States Constitution, section 9, clause 7, states that "No money shall be drawn from the Treasury, but in Consequence of Appropriations made by Law..." This is what gives Congress the power to make these appropriations. The President, however, still has the power to veto appropriations bills. while the Bureau of Reclamation oversees federal dams, irrigation, and rural drinking water projects in the Western United States.
