it is repoi'ted to have cost f 1,100. The weir or gate in Bogg Slough at the head of 

 Stimson Canal is a massive structure, 51: feet wide, erected at a cost of $2,000, and 

 was built in 1897. The canal headgate was originally a light structure that cost 

 about $400; it was washed out in June, 1894, and replaced bj' a new gate, 40 feet 

 wide, at a cost of about $600. 



CAIiAMITY DITCH. 



The Calamity Ditch was constructed in 1894. It is a high-water ditch about 16 

 feet wide on the bottom, having its headgate located near the edge of the swamp 

 and overflow land about a mile to the northward of Summit Lake and just south of 

 Cresctent Canal. The ditch has a northwesterly course, is several miles in length, 

 and supplies water for about 1,.500 acres of land. Its cost of construction is reported 

 at $1,000, and the annual expense of maintenance $100. Water is generally available 

 from the beginning of May to the end of July. The ditch is owned b\' the land- 

 owners whose farms are served with water by it. 



HITE DITCH. 



The Hite Ditch was original!}' constructed as a branch of Stimson Canal, but 

 owing to the unreliable flow of water in Stimson Canal, due largely to litigation with 

 the owners of the Crescent Canal, an independent diversion of water was effected b}' 

 the irrigators whose lands were served by the Hite branch. The ditch was con- 

 structed several j'ears ago. It has a headgate 9 feet in width, placed in the reclama- 

 tion levee on the west side of Bogg Slough, near the point where the Stimson 

 Canal receives its water. This ditch receives water only for a short period each 

 year, and irrigates about 500 acres of the reclaimed lands in Fresno Swamp. The 

 ditch is but poorly maintained, and is reported to have a capacity of 15 to 20 cubic 

 feet per second. 



JAMES EAST SIDE CANAL. 



The James East Side Canal receives its water from the eastern side of Murphy 

 Slough, just above the head of Steamboat Slough, which is one of the water courses 

 of the Fresno Swamp region. It has a northwesterly course for a distance of about 

 15 miles, skirting the easterly edge of the submersible lands of Fresno Swamp. The 

 canal was constructed by J. G. James in the fall of 1885. It was made 10 feet wide 

 on the bottom and to carry water 2 feet in depth; width and depth have been gradu- 

 ally increased to a present bed width of 20 feet and a depth of 4 feet. Water is 

 admitted into the head of the canal without being under control of a check weir or 

 headgate, and parts of the canal have assumed the appearance of a natural water- 

 way. Water from this canal is used only for grass-land irrigation. It is reported 

 that as much as 5,000 acres have been irrigated in one season. The canal capacity 

 has l)een estimated at 75 cubic feet per second. 



JAMES WEST SIDE CANAL. 



I'he James West Side Canal was constructed in 1892-93 bj' J. G. James along 

 the western margin of the Fresno Swamp lands. The point at which it diverts 

 water from one of the Fresno Swamp sloughs is about 8 miles below the point at 

 which the East Side Canal receives its water. In 1889 the original West Side Canal
