4D=(3)- Rattlesnake t!reek o-" (July 30, 1935 and August 31 to 

 September 3, 1936,; Tl^iteieatherj BurrowSj and Hana-rano) Enters the 

 Naches River 25 l/2 miles upstream and is 23 miles longj, the lower 

 17.7 miles to Little Wildcat Creek having been surveyed. The stream 

 extends through a rugged mountainous canyonj, and has a fairly steep 

 gradiento A flow of 93 CofoS^ was measured at a point 4 miles upstream* 

 Logging operations on the lower watershed cause fast freshet rises and 

 bartk erosion. Good spawning riffles were found turoughoutj, with the 

 best spawning areas being in the lov;er 3 miles, and betv/eon 15 and 16 

 miles upstreamo Resting pools are numoraois, though not well protectedo 

 The ivater temperature was 52 -55 F in the lower portion and 42 -49 F„ 

 in the upper portiono Chinook salmon in small numbers are reported to 

 enter the stream in the years when conditions are favorable for passage 

 up the Yakimaj and particularly over the Sunnyside Damo Obstruction and 

 diversions are as f oliovifs s 



An irrigation diversion 1/4 mile upstream on the south barJc diverted 

 4 Cof oSo It had a lov; rock diversion dauij and has since been screenedo 



An irrigation diversion Oo9 miles upstream on the north bank and 

 above a log T/ing dam was diverting 3o6 CofoSo and v;as unscreened. 



Ari irrigation ditch lo2 miles upstream on the north barJc above a 

 log wing dam was diverting 12o7 cnfoSoj and was unscreenedo 



A small irrigation ditch 4o3 miles xjpstream on the south bank 

 above a board wing dam is unscreenedo 



A cascade falls 16 1/2 miles upstream is only 8 feet high^ but the 

 water is spread out over so great a surface that it is too shallov; for 

 fish to pass during low water periods.^ 



4D"(4)o Bumping River o°°-° (July 25-27, 1935s Whiteleather and Burrowso) 

 Enters the Naches 42 miles above the mouth and extends for a distance of 

 24 miles,, of which the lower 16o3 miles to Bumping Lake is accessible to 

 fisho An impassable storage dam at the outlet of the lake was the upper 

 terminus of the surveyo This dam is 45 feet high above the stream channel 

 and spills through a 7 foot wide conduit into a deep pool belowo It is 

 believed that most fish can pass out of the lake into the stream without 

 iriju-yo The river is 50 to 70 feet wide, has a gradient of 53 feet per 

 mileo The only obstruction below Bijmping Lake Dam is a log jam 20 to 40 

 feet high located 13o7 miles upstreamo This is passable at normal water 

 stages by a side channel around the jam, but may be a barrier to fish at 

 low water stages. 



The river flow is controlled by the discharge at Bttmping Lake Dam, r.rA 

 from April through August it is usually 100 to 600 o.fcS. From September 

 through November it is generally 30 to 90 Cof.So and from December through 

 Mar:h it is quite variable, generally being between 3 and 190 CofuS. (u^SoGoS. 

 records taken at a station 1/4 mile belov/ the dam). There is no cultivation ir 

 the valley, which has steep fortistad slopes. There are good spawning areas 

 and good resting pools along the entire river below the dam. More good 

 spawning areas are located in the main stream and tributaries above the dam, 

 but are inaccessible at present. There were formerly good runs of spring
