Officials say more than 1,100 public comments were submitted for the proposed Lake Powell Pipeline designed to pump water to two southern Utah counties.
The Spectrum reports the proposed 140-mile road is estimated to cost between $1 billion to $1.7 billion to be repaid over 50 years.
Critics say the pipeline is an unnecessary use of funds.
Bureau of Reclamation officials will consider all the comments before releasing a draft environmental impact statement.
Officials say the draft is the first step in the year-long National Environmental Policy Act.
Another public comment period will open after the department releases the draft.
