A volume of water, very considerable as compared with the ordinary 

 flow of the stream, is diverted from the Weber Eiver for purposes of 

 irrigation. 



The main channel discharges over a well-defined fan, which extends 

 about 1^ miles from the present shore line. The shores here are formed 

 by a part of the delta laid down during a higher stage of water than 

 now obtains, and the slope is so gradual that the position of the water 

 line fluctuates widely under the influence of the winds and slight 

 changes in the lake level, a rise of an inch changing the position of 

 the shore line north of the river mouth by several hundred yards. 



The water on the fan is practically fresh, but at its edge, where the 

 slope becomes more abrujit, the density falls rapidly. On October 18, 

 1898, about 1^ miles from shore the salinometer registered a density of 

 1.0315 in a depth of 1 foot; 50 yards nearer the shore the depth had 

 decreased to 7 inches and the density to 1.0040; 50 yards farther in 

 the depth was 5 inches and the density 1.00L*0, and 100 yards farther 

 the readings were 4 inches and 1,0005, respectively. The water on the 

 fan was clear, but the salt water around the rim had a milky appear- 

 ance, probably due to the imiserfect solution of its saline contents on 

 account of its low temperature, 12^0. (53.6'3F.). The bottom on the 

 delta is generally firm and there is an abundant growth of diatoms. 

 Both of these conditions are favorable to the growth of oysters, but the 

 density is fatal and the extreme s^liallowness objectionable. 



BRACKISH SPRINGS. 



After the completion of the examination of the lake at the mouths of 

 the main streams flowing into it, it appeared desirable to investigate 

 some of the numerous brackish springs which are characteristic of the
