Measured June 14, 1882, on 
Gould ranch north of 
Fresno. Average width, 3 
feet; shade trees along por- 
tion of ditch, and banks 
overgrown with grass; weir 
used. 
Measured June 21, 1882. 
Lateral of main supply 
canal; about 2 feet wide; 
weir used. 
Measured June 26, 1882. Di- 
verts water from Fresno 
Canal at point 4 miles east 
of Fresno. Average width, 
8 feet. 
31 diversions in this length. 
Increase thought to come 
from irrigated lands west 
of Palisade. 2 
At numerous places small 
trickling streams could be 
seen issuing from canal 
bank. 2 
Water section entirely in ex- 
cavation; considerable side- 
hill. 
Same as foregoing but mostly 
along sidehill. 
Comparatively level cross 
slopes. 
Comparatively level cross 
slopes; in excellent condi- 
tion. 
Receives heavily laden silt 
waters, flood time only. 
Canal follows river for 11 
miles. 
Some land irrigated above 
ditch from Dixon Canyon. 
Some land irrigated above 
ditch from Spring Canyon. 
2 Combining these two measurements shows gain greater than loss.
