COLORADO RIVER BASIN SALINITY CONTROL ACT

in room

The purpose

MONDAY, MARCH 4, 1974

HOUSE OF REPRESENTATIVES,
SUBCOMMITTEE ON WATER AND POWER RESOURCES
OF THE COMMITTEE ON INTERIOR AND INSULAR AFFAIRS,

Washington, D.C. The subcommittee met, pursuant to notice, at 9:50 a.m., 1324, Longworth House Office Building, Hon. Harold T. Johnson presiding

Mr. Johnson. The hour of 9:45 having arrived, the Subcommittee on Water and Power Resources will come to order.

of our meeting this morning is to receive testimony on legislation pending before the committee and having to do with the Colorado River and salinity matters.

At this time I want to recognize the former chairman of the Interior and Insular Affairs Committee for many years, a very able friend and supporter of all things good for the Colorado River. He has spent a lifetime in public life, a good portion of it here in Washington, and most of that time dealing with the Colorado River.

So we are going to give you the title this morning of Mr. Chairman Emeritus. We are glad to have you here, Wayne, and glad to see you looking so well.

Mr. ASPINALL. Mr. Chairman, may I just take a minute to reply?

Members of the committee, when I heard that you were having an important hearing on Colorado River basin matters, I wished to be present. I had no idea that I would be sitting up here, Mr. Chairman. I thank you very much for permitting me to be next to you.

I see in the room many of those men with whom I have worked for many years, all of them trying to figure out some way to take care of the problems of this great river.

It is nice to be back again. I feel at home, Mr. Chairman, but I can tell you there is a lot of solace and pleasure in being away from Washington most of the time these days. Thank you very much.

Mr. Johnson. Ănd I might say, you look that pert this morning. You look fresh, happy and relaxed, younger, too.

Mr. Aspinall. Thank you, Mr. Chairman.

Mr. Johnson. The bills which we will be considering today are listed on the agenda sheet before each member, The Chair suggests a format for today's session that is slightly different from our usual practice. Unless there is objection, I will call Mr. Brownell, Secretary Horton, Ambassador Bowdler and Commissioner Friedkin to the witness table all at the same time.

(1)

I see you gentlemen are all here this morning, and if you do not have any objections and there is no objection from the committee, that will be the format. I think it will allow for a more orderly procedure here, do away with duplications and save time so that we can get all of the facts.

We will let each of you gentlemen deliver your prepared statements and then after all of you have been heard we will go into questioning because you are the experts, in this very important matter that is pending before our country, the country of Mexico and the States that make up the Colorado River basin.

At this time, unless there is objection, I would like to place in the record a copy of H.R. 12165, H. Ř. 12834, H.R. 7774 and H.R. 7775. H.R. 12165 and H.R. 7774 are measures which were initiated in the committee and for which departmental reports have been requested from the Departments of Agriculture, Interior, State, and the Environmental Protection Agency.

Unless there is objection I will ask that these reports be placed in the record at this point.

Is there objection?

Now, accompanying the reports, we have four very important documents. I would ask unanimous consent that they be placed in the committee file at this time. Ahead of them I would like to ask unanimous consent to have placed in the record the comments on H.R. 12834 which are contained in the executive communication from the Departments of State and Interior under date of February 7, 1974. This is a very important communication and I would ask that it be placed in the record.

Is there objection?
Hearing none, so ordered.
