Early Floods in Los Angeles: Interview 147, J. E. Proctor, Long Beach: It was not necessary to fertilize the land…
July 16, 2016 § 1 Comment
One of the best creek freak documents around is a series of interviews made by Los Angeles County Flood Control Engineer James Reagan, around 1914. The interviews give a vivid picture of the Los Angeles basin of more than 100 years ago. We will be posting other interviews from this document in the following months.
He has been in this section of the country for more than forty years, and has witnessed some big floods. They have never done the damage that the flood last winter did, for the reason that everything is different. In the early days, and up to within the last four years, the country was covered more or less with willows, brush fences, and in some places, lakes, marshes and other small growth. In those days the water would spread out all over the country, and the velocity was very much slower, it did no damage, and in many ways did good.
It was not necessary to fertilize the land, as they are now doing. They raised 100 bushels of corn to the acre, but not now. In those days a crop of corn and California pumpkins were raised on the same land. Those pumpkins would grow so thick that it was difficult to walkaround and step between them, while it was an easy matter to go all over the place and never step on the ground, stepping on the pumpkins. The largest I ever saw weighed 214 pounds, and on our place we raised one that weighed 206 pounds.
So in this way the floods did a great deal of good. Each flood left a deposit of silt on the land that made the rich yields of those days. I am afraid the people will miss those floods, although in the last flood the land was washed very badly. That washing comes from the land being cleared off and having a freer run than before. There were no railroad embankments in those days either to hold the water either, where it is now held up, and the volume contracted into a smaller space at the openings under the railroad. And too, a flood would break out and a strong current would cut across the country carrying things before it, and in the wake perhaps putting a channel that ruined the land. Therefore part of the flood carried the big amount of silt, but the deposits were left by the last part of the flood.
On our place we have no fear of the flood that first comes, that does no damage, but it is the tail end of the flood that causes the damage. A place is started below us, and should a flood come again as last winter it will probably cut back and ruin our place. As it is we could do nothing with it this year; we could not rent it for anything.
Many peculiar things were noted in the flood of last winter. We had a chicken yard about 50 feet square, made of woven wire chicken fencing. On the inside of this fence, when the flood had gone down we found a deposit of sand and silt inside the yard about three feet deep. And another at a lower corner of the fence, a single strange of barb wire about 100 feet long, got loose except at one end, where it was held. Along this single strand of barb wire as it lay down stream had gathered a sand bar just back of the wire, or just below it, about 18 inches high.
These two things show what small obstructions can do. It gives us an idea of how little it takes to gather the silt, to form an obstruction that will soon turn the stream in some other direction.
So for a protection to the land I believe that a mat of willow roots and boughs would be more effective than anything else outside of a solid concrete wall and flood conduit for the water to travel in.
A channel 500 or 600 feet wide would probably carry the flood of last winter, but some of the others I could not say. The only objection to a wide channel is that when the tail end of the flood is running off it is liable to start zigzagging across the channel and then it is liable to cut the embankment. As long as the channel is clear and straight and enough water to partially fill the channel, everything would go all right, but the small stream that will not fill the channel will do a great deal of damage.
It is easy to get the willows to grow, they will grow anyway. The best way is to get branches as long as possible, lay them with the buts upstream, and then partially cover the with sand. They should be placed at the bottom of the embankment in the river bed, and then they will get plenty of moisture.
Mere sand banks will not do. They will melt down like sugar. But something should be done, but not any great expensive works until they work out the most effective methods of handling the water. I have worked in water all my life, and have seen some funny capers by it….
The second half of the interview, perhaps to be transcribed at a later date, describes the different qualities of well water at different strata.
