FORTIETH BIENNIAL REPORT 59 



DILL, William A., & SOULE, Scott M. 



Paper work in fish management. Report No. 3. Establishment of standard 

 methods. Submitted January 25, 1947. 11 pp. including 2 figures. 



Abstract: Discusses need for uniformity and correlation in: Records of all 

 flies (in all offices) concerned with management; and in all instructions for use 

 of files, forms, and procedures. Outlines present status of "standard" sets of 

 instructions: Stream and lake survey (and forms) ; use of management binder 

 system ; filing and indexing of all types of stream and lake records. Defines 

 "standard" methods and procedures. Explains necessary steps to take in prepar- 

 ing them and explanations. Lists bottlenecks to accomplishment of above. 



Paper work in fish management. Report No. 4. A suggested set of instruc- 

 tions for use of the management binder system. Submitted January 25, 1947. 

 3 pp. letter plus set of instructions, ii plus 23 pp. (incl. 1 fig.) plus 4 pp. addenda. 

 Abst7-act: Instructions designed for use of hatcherymen, biologists, central 

 office. Explains forms used in binder, how to fill them out, their arrangement and 

 indexing ; how to keep binders up to date ; interrelationships of the three offices. 

 Has filled-out sample forms. Accompanied by letter of explanation and miscel- 

 laneous addenda. 



A fisheries survey of lakes in the Granite Creek Drainage, Madera County, 

 1946. Submitted April 29, 1948. 52 pp. including 3 figures (maps), 8 tables and 

 2 appendixes. 



Abstract: Results of a July 1946 survey of 24 natural high-altitude trout 

 lakes. Explains why past management has not been satisfactory, (^ives general 

 description of drainage, lakes, fish populations, accessibility, and fishing intensity. 

 Compares past stocking with present fish populations. Recommends definite man- 

 agement practices including a new stocking policy, improvement work, improve- 

 ment of field knowledge (by hatchery personnel) and records. Recommends addi- 

 tional surveys in areas. Gives methods (including a stocking table) and itinerary 

 of 1946 trip. It is shown that despite little stocking, the "carry over" of hatchery 

 fish may be high, and that natural propagation may often be sufficient to provide 

 satisfactory fishing. 



EVANS, Willis A. 



Reconnaissance of Upper Sweetwater River, San Diego County, with refer- 

 ence to stream improvement. Submitted August 30, 1946. 8 pp. plus 1 map. 



Abstract: The Sweetwater River was examined from Lake Loveland to 

 headwaters. Conditions found unsuitable as year around habitat for trout below 

 Hulburd Grove. Area within Cuyamaca State Park is only section satisfactory 

 for permanent trout stream. Cold Spring Creek is best area. A two-mile section 

 of it is recommended for stream improvement work in form of small rock check 

 dams, done cooperatively by Division of Fish and Game and Division of State 

 Parks. After improvement, plant with aged fish. Extreme headwaters should be 

 planted with fingerling RB trout at periodic intervals of 4-5 years. The map indi- 

 cates section of stream suitable as trout habitat. 



ERASER, J. C. 



Poisoning of McMurray Lake, Nevada County. Submitted January 15, 

 1948. 9 pp., 1 photo, 1 table. 



Abstract: McMurray Lake, Nevada County, was poisoned with rotenone on 

 September 14, 1947, to rid it of a large population of catfish. Report describes 

 character of the lake, the poisoning program, and observations made during and 

 after the poisoning. Seven brown trout were recovered and 22,672 catfish with an 

 average length of 4.7 inches were actually counted. Catfish population was esti- 

 mated at 33,000. 



The Frog Lake (Nevada County) Fishery in 1947. Submitted March 21, 

 1948. 10 pp., 5 tables. 



Abstract: 203 anglers fished 767 hours and caught 431 trout as follows: 

 RT 85 (20 percent), EB 128 (30 percent), BN 218 (50 percent) ; average catch 

 per angler 2.1 ; per angler hour 0.56. Fishing better than in 1947. BN still domi- 

 nate catch ; EB are increasing, probably due to natural reproduction ; RT not 

 increasing significantly. Marked KT were planted in 1947 in four groups ; spring 

 spawning and fall spawning from Mt. Shasta ; same from Tallac. Objective : To 

 determine relative survival by intensive counts in 1948. 



MURPHY, Garth I. 



A survey of Stony Creek, Grindstone Creek, and Thomas Creek drainages 

 in Glenn, Colusa, and Tehama Counties. Submitted September 2, 194G. 28 pp., 

 25 photos. 



Abstract: Brief survey to determine extent of trout in above drainages. In 

 general trout water starts at 2,500 feet. Streams are relatively inaccessible, and 

 well stocked with trout. Little planting needed. Streams lack adequate shade 

 causing excessively warm water. Several possible hatchery and rearing pond sites 

 discussed. Recommended : That a holding pond be established to accommodate 

 at least 37,000 RT at 15 per ounce and that these fish be distributed by pack stock 

 in Middle Fork of Stony Creek, Grindstone Creek, Killdry Creek, and Thomas 

 Creek, that in cooperation with U. S. Forest Service increase of shade be attempted 

 experimentally by planting willows and alders on a one-quarter mile section of 

 South Stony Creek.
