The amount of $400,000 is requested for continuation of 1 study in fiscal year 1962.

10

Mr. RARAUT. Where is the Bolinas Channel Harbor and how far is it from the nearest existing harbor refuge?

General MACDONNELL. It is 11 miles north of San Francisco Bay, and 41 miles south of the next harbor to the north, which is Bodega Bay.

Mr. RABAUT. How long has it been since we last deepened the Stockton Channel?

General MACDONNELL. About 1935.

Mr. RABAUT. Are you just making a study of it now?

General MACDONNELL. Yes, sir.

Mr. RABAUT. Has the Cosumnes River study been continuously active since funds were last appropriated for it?

General MACDONNELL. Yes, sir; however, last year, Mr. Chairman, the Cosumnes River and the Mokelumne River studies appeared as a combined study and was so funded. This time they have been separated into two studies with a view toward early completion of the Mokelumne study and somewhat later completion of Cosumnes.

LYTLE CREEK, SAN BERNARDINO

Mr. RABAUT. Why is it necessary to start a new study on Lytle Creek, San Bernardino, at this time when there are so many current surveys going on in California?

General MACDONNELL. This is in San Bernardino, Calif., which is a rapidly growing area. It is subjected to flooding from the east branch of Lytle Creek. This is a review report to determine the channel condition-it has been deteriorating-and to determine if conditions of growth are such that flood protection is warranted.

Mr. RABAUT. This growth is in population?

General MACDONNELL. Yes, sir.

Mr. RABAUT. Have you not attempted to keep this channel clear? General MACDONNELL. This is a branch of the Lytle Creek which is not a part of a Federal project. It does carry some releases which are diverted from another part of a Federal project. It has become overgrown and has been infringed upon by residences and other developments. It is a question of determining whether that channel will carry the runoff that can occur in the type of storms that they have.

SANTA YNEZ STUDY

Mr. RABAUT. Has the Santa Ynez study been active continuously since funds were last appropriated for it?

General MACDONNELL. There were no funds appropriated in 1961. That study was suspended in 1948. It was resumed in the spring of 1960 with some funds that were carried over from 1959.

Mr. RABAUT. Why did we start it over again?

General MACDONNELL. This a question of a multiple-purpose dam above Lompoc, Calif., which is now under study, and the belief is at this time with the available information that we have, that we should complete the work. The funds requested will complete this study.

DOLORES RIVER STUDY

Mr. RABAUT. Last year you said you would complete the Dolores River study in this current year. Now you are asking programing funds for 1962. Why?

General MACDONNELL. Yes; as you know, the conditions that pertain to a study over a particular area can vary from week to week or month to month. For the most economical use of funds we transferred $3,000 out of that study in fiscal year 1961.

Mr. RABAUT. From the Dolores River funds?

General MACDONNELL. Yes; they were transferred to the Gila River-Pinal Creek study.

SAN FRANCISCO MODEL STUDY

Mr. RABAUT. What savings in maintenance dredging have been realized as a result of your San Francisco model study? Why has the cost again been increased by $90,000?

General MACDONNELL. The first part of the study that has been undertaken and is now complete in draft form, is the question of salt water barriers. We have also investigated the movement of pollutants in the area. Beginning the first of May, the emphasis will be to determine silt movements. As yet, we do not have a definite answer. Mr. RABAUT. Can you pinpoint specific savings?

General MACDONNELL. No, sir; not on the silt movement because that part of the study will be undertaken in the beginning of the

summer.

To answer your second question, the cost estimate did increase $90,000. That is because $80,000 were expended some years ago on the preliminary examination but have never been shown as a cost against the project. They should be so shown, and that $80,000 plus another $10,000, which is a bookkeeping transaction for certain procurements, do not increase the amount of funds needed to complete. Mr. RABAUT. Does this constitute the $90,000 that is here? General MACDONNELL. Yes, sir.

SACRAMENTO-SAN JOAQUIN REGION STUDY

Mr. CANNON. Please explain the purpose of the Sacramento-San Joaquin region study.

General MACDONNELL. This study has as its purpose to evolve a plan in conjunction with the State to correlate the preservation of the natural recreation resources of the area with the flood control program, and then to determine what the effects might be on the Federal projects if that plan was executed, and to establish the proper proportioning of the costs.

Mr. RABAUT. Apportioning of the costs between whom?

General MACDONNELL. The local interests and the Federal Government. If those costs cause the Federal Government to have any expenses that they would not otherwise have, then they should be set forth in this document, with a clear understanding of who is to pay. Mr. KIRWAN. I do not have any question on the general investigations.

PROJECTS CONTINUING BUT NOT BUDGETED FOR 1961

Mr. TABER. Will you please explain why most of the studies shown appear to be continuing studies, but yet many were not shown in your request for fiscal year 1961.

General MACDONNELL. Five of them, Mr. Taber, start in fiscal year 1962. They were not budgeted last year or any previous year.

Mr. TABER. Will you list them.

General MACDONNELL. Streams in San Mateo County, SacramentSan Joaquin region study, the Atherton Creek study, the study of Bolinas Channel and the study of Lytle Creek.

Mr. TABER. When was the last work done on each of these studies that were not in the fiscal 1961 budget?

General MACDONNELL. There was no work prior to the submission of this budget.

Mr. TABER. They are regarded as needed by you?

General MACDONNELL. Yes, sir.

Mr. TABER. Why?

General MACDONNELL. In the case of San Mateo County and Atherton Creek, these are urban areas respectively about 20 and 30 miles south of San Francisco in highly developed areas that are subject to frequent flooding from runoff from a very steep mountain formation. For example, in San Mateo in the flood of 1958 alone there were 900 homes damaged. The matter of Lytle Creek and Sacramento-San Joaquin region study we have discussed, and also, Bolinas Channel to some extent. That is primarily a question of harbor refuge.

Mr. TABER. Will this complete the work on each of those?
General MACDONNELL. No, sir, this is the first allocation.

Mr. TABER. Can you give some rough estimate as to the probable Federal cost for each of these projects?

General MACDONNELL. Not at this time since we have not pursued any study of the areas. We have only authorization to study them but no funds as yet to do that. I could give a personal estimate as to Atherton Creek. I know it would be more than $400,000, but I think it would be less than $1.5 million. That is for the project, not for the study.

Mr. TABER. Are any of these jobs being contributed to by the local interests?

General MACDONNELL. Not so far as general investigations funds are concerned, sir. I would assume that the application of normal policies would eventuate in certain participation by local interests at · the time the survey documents are submitted.

CRESCENT CITY HARBOR AND HUMBOLDT HARBOR BAY

Mr. TABER. Regarding Crescent City Harbor and Humboldt Harbor Bay, what increased depths are being considered at each one?

General MACDONNELL. At Crescent City it is now authorized at 20, and I believe I can say in general terms that the possible deepening would be to 25. There might be areas where it would be something else, but in general terms that is so.

In Humboldt Harbor there would be a possibility of deepening the channels 5 feet. The navigation channels are now 30 feet and this would consider 35. Over the bar where they have very high swells and a great deal of variation in the distance between a ship's keel and the channel bottom, it would be a question of increasing the depth from 40 to 45 feet.

SAN FRANCISCO BAY TO STOCKTON

Mr. TABER. Can you give us some idea of the extent and cost of the project under consideration for San Francisco Bay to Stockton?

General MACDONNELL. This is a matter, again, sir, of 5-foot increases in project depth if they are justified. The overall cost I am not in a position to state, because we have not yet done the study, but I would not consider it an unreasonable figure compared to the present status of that project.

ATHERTON CREEK

Mr. TABER. On this Atherton Creek project, page 6, what urban areas are involved in that?

General MACDONNELL. This involves all of the city of Atherton which is a suburb of San Francisco, although in San Mateo County, parts of Redwood City and parts of Glen Oak Park.

CACHE CREEK

Mr. TABER. What about the Cache Creek project? Does the municipal water supply system enter into that?

General MACDONNELL. It has not been determined what part, of the water in any multiple-purpose reservoir that might be built there, would be municipal water. But municipal water is, however, sir, always a consideration in a project anywhere around that area. would be some, but how much it would be, sir, I do not know. Mr. TABER. Would it be the major part of the project?

There

General MACDONNELL. No, sir, I do not believe it would be. I think both flood control and irrigation would involve greater quantities than municipal and industrial water. As I say, the study is only just in progress.

Mr. TABER. But there will be no contribution on the part of the local interests, to the study anyway?

General MACDONNELL. Not to the study, no, sir.

Mr. TABER. Why is that when it is probable that they will be amongst the principal beneficiaries?

General MACDONNELL. The benefits will accrue primarily to certain specified parts of the area. In the event that those benefits should be local in nature so far as flood control is concerned, they would pay as though it were a local flood control project.

In the event that municipal and industrial water turned out to be a feasible part of the development, they would then pay the costs of that. The same is true of irrigation.

Mr. TABER. I think that is all I have.
