Show Creek Reservoir. These spills would usually occur in May and June since the Strawberry Aqueduct would be flowing full during this period,, The magnitude of this potential loss averages about 3,000 acre- feet annually. ( h) Layout Creek Strawberry Aqueduct would intercept Layout Creek at a point about 2.0 miles above its confluence with Currant Creek. There are no stream gages on Layout Creek. All flows up to the 20- c. f. s. capacity of the inlet structure would be diverted to the aqueduct. Average October to March winter flows at the aqueduct, based on area- altitude runoff studies, would be expected to be less than 1 c. f. s. Any flow passing the diversion structure would reach a geological sink that occurs about 1,000 feet downstream. There is no apparent surface streamflow in Layout Creek for a 1.2- mile distance from the sinks to a series of springs which emerge about 0.4 mile above the confluence with Currant Creek. Diversion of the stream above the sinks would probably cause a reduction in the flow of the springs. The proposed annual diversion from Layout Creek has been estimated to be 1,300 acre- feet of water. An estimated 300 acre- feet would be spilled during the high runoff period. Layout Creek does not support a significant sport fishery and did not merit a classification by the State Division of Wildlife Resources. The reduction in flow in the 0.4 mile of stream below the sinks would adversely affect the minor fishery that does exist. ( i) Water Hollow Water Hollow Diversion Dam, an appurtenance of Strawberry Aqueduct, intercepts Water Hollow Creek at a point 4.5 miles above the confluence with Currant Creek and 3.5 miles above U. S. G. S. Gaging Station No. 9- 2875. Flows up to the 20- c. f. s. capacity of the inlet structure would be diverted, except for minimal |
