estimated that fifty horse power can be developed with a full gate open- 
ing. A thirty-five horse power steam engine is nsed in conjunction with 
the water power when the mill is run to its full capacity and during time 
of low water. The dam was built in 1890. The machinery is valued at 
$5000. 
About six miles east of Georgetown is located the flour and corn mill 
of J. F. Towns, on the San Gabriel river. The power is derived from one 
26-J-inch Leffel turbine and is estimated at thirty-six horse power under 
the sixteen foot head obtained. The dam is constructed of timber frame 
work and a top sheeting, similar to the one at Jonah, except that the 
posts on the down stream face are slightly inclined instead of being ver- 
tical, and that there is no cap on the top of these to support the stringers 
for the sheeting. Each stringer rests on the head of a post and the sheet 
planks are nailed directly thereon and lengthwise of the dam. The posts 
are about eight feet apart, and a wooden sill embedded in concrete is 
placed the full length of the dam at the foot of these posts to strengthen 
against sliding. The dam is connected to the river banks on both ends 
by stone abutments. It is about 400 feet long and six feet high, and was 
first built in 1882. In 1892 it was rebuilt entirely as it stands today. 
The power house is located about one-fourth of a mile below the dam and 
a head of sixteen feet is obtained on the turbine. The water is conducted 
to the power house by a race. The cost of the plant, dam, machinery, 
etc., was about $8000. At present the river is- so low that the mill is not 
run, but when the water supply is sufficient it is run day and night. 
About three miles northeast of Georgetown is located a small corn mill, 
owned and operated by D. A. Strange. The mill is situated on the banks 
of Bear creek, but obtains its power from a spring, the water of which 
is backed tip by a clam and forms a pond or small lake above the mill. 
The dam is built of limestone masonry, is of irregular section, and is 
about 150 feet long. In plan it is approximately trapezoidal in shape, 
and the mill is situated in the middle of the section at' right angles to the 
river. The effective head is sixteen feet, and with the 16-inch turbine 
twenty-iwo horse power can he obtained. The mill is a very small con- 
cern, the machinery old and very seldom used.
