catches. About 60 percent of total anglers fished from shore and accounted for 49 

 percent of total catch, as against 40 percent who fished from boats and made 51 

 percent of total catch. Estimated total number of anglers was 1,044 and total catch 

 was 5,683 trout. Recommends further creel studies at Hume Lake and a comparative 

 study of Hume and Sequoia Lakes, stocked with spring and fall spawn stock rain- 

 bow respectively. 



Power development of Kings River drainage, Fresno County. California. Re- 

 port Number 2 : North Fork of Kings River. Submitted October 21, 1949, viii plus 

 56 pp., including 19 figures and 3 tables. 



Abstract : Describes the North Fork Kings River, its present trout fishery 

 and power development. Lists the proposed power developments as planned by Pacific 

 Gas and Electric Company, Fresno Irrigation District, and the U. S. Bureau of 

 Reclamation. Discusses the probable effect of these developments on the fishery. Con- 

 cludes that the fishery can be partially saved by water releases of between 3 and 4 

 percent of the mean annual flow of the river, or that it could be replaced in kind by 

 improving or creating other fishing waters at the expense of the agency developing 

 the power resources and that the fishery should be saved by one of these two means. 

 Recommends that the Division of Fish and Game notify all interested agencies of 

 the threatened loss of fisheries value and negotiate to save the fishery by obtaining 

 water releases or by a replacement of the fisheries value to be lost by having agency 

 developing power improve other waters. 



Occasional creel censuses at Hume Lake, Fresno County, during 1949. Sub- 

 mitted April 7, 1950. 1 plus 31 pp., including 14 tables. 



Abstract : Describes Hume Lake (94 acres) briefly ; gives summary of stock- 

 ing since 1947 (i.e. after last poisoning) . Results of 8 creel checks show fishing good 

 early May but poor late May through mid-September, then picked up to fair by 

 season's close (October 31). The estimated total season's catch was 17,000 rainbow 

 trout, by an estimated 7,000 angler-days of fishing (estimated average catch/day 

 of 2.4 and estimated average catch/hour of 0.51). Season's pressure estimated at 74 

 anglers/acre ; season's catch estimated at 180 rainbow trout/acre. Angling pressure, 

 catch and stocking data are compared with same for Castle, Crystal, and June Lakes. 

 Concludes that nearly all of the 1949 catch was of planted rainbow trout and 

 discusses their age, growth and condition. Estimated about 75 percent of basic 

 annual plant (30,000 spring-spawn rainbow trout at 4i inches in September) was 

 harvested in 1949, and on basis of estimated $35/M planting cost, each creeled 

 rainbow trout cost slightly over 6 cents. Recommend continuation of present basic 

 stocking policy and trial planting of 10,000 catchable rainbow trout spaced during 

 summer. Concludes that unless trial planting of catchable rainbow trout succeeds, 

 there is little hope of raising the quality of angling during mid-season months when 

 the lake temperature attains or exceeds 70 degrees F. Recommends further O2 and 

 temperature studies and investigation of success of spawning in tributary streams.

Pine Flat Reservoir, Fresno County. Submitted July 12, 1949. 15 pp. plus 

 1 table and 1 plate. 



Abstract : Chronological summary of all developments re permits and protests 

 on Corps of Engineer's Flood Control Project on Kings River near Piedra. Describes : 

 river and fishery in project area ; projected dam, reservoir and its operation ; effect 

 on fishery. Dam will store 1 million acre-feet with surface area of 5,900 acres. 

 Fluctuation may be 393 feet annually, and no provision is made for dead storage. 

 Report gives recommendations for minimum pools, impoundments outside reservoir 

 area if minimum pools are not provided, construction of borrow pits to provide fishing 

 ponds, screens, minimum flows below dam. Suggests these recommendations be put 

 into form of a resolution by California Fish and Game Commission.

The creel census at Rush Creek Test Stream, Mono County, California, season 

 of 1948. Submitted November 30, 1948. 15 pp., 5 tables, 2 figui-es, 1 photo. 



Abstract : Tlie creel project at Rush Creek was operated for a total of 169 

 fishing days. All plantings were doubled over 1947 and a 3-day post-planting closure 

 following each catchable plant was tried. From April 28 to August 11, 1948, 19,945 

 rainbow trout averaging 7 inches long (marked right ventral) were planted. (5 

 spaced plants each of about 4,000 rainbows were made). On October 13, 1948, the 

 second winter carryover plant of 8,000 rainbows (average 4 J inches) was made; as 

 in 1947 these plants were made in two groups of 4,000 each : fall-spawned from
