Republicans say these rules have led to a man-made drought, and their bill would re-instate an older agreement that would allow California to manage the competing interests of wildlife preservation and the human population's demand for water. In addition to the bill itself, members will consider nine amendments, most of which are from Democrats.

The Obama administration said on Wednesday that it opposes the bill and would veto it, although the Senate is not expected to take it up anyway.

Members will also consider H.Res. 556, which condemns the government of Iran for its imprisonment of Youcef Nadarkhani, a Christian who has protested Iranian law requiring him to teach his children the religion of Islam. This resolution will be considered under a suspension of House rules, which will require a two-thirds majority vote.

Also on the suspension calendar is S. 1134, the St. Croix River Crossing Project Authorization Act, which conditions the building of a bridge over the St. Croix River.

Additionally, a vote is expected on H.R. 3902, which revises the timing of special elections for local office in the District of Columbia.

The Senate returns at 9:30 a.m. to again take up the Senate Democratic version of the highway authorization bill.
