I specific gaging stations right up in the collec- tion area were not available early in the game. However, we have not gone ahead with this proj- ect on the basis of one year's study. Ue have had reliable records further downstream which our hydrologists, in cooperation with the Geological Survey, have been able to project into the higher mountains and these forecasts of runoffs cover the entire period of study which originally was 47 years. At the present time we have, as ltr. Odell pointed out, put in some additional stations which have been in operation for four or five or six years in some cases and that will afford us an opportunity to project those water yields even further. Mr. Odell and the Geological Survey at the present time are reading stations, as he pointed out, higher on our collection system. On the Frying- pan River itself, on the South Fork and on the North Fork, right up in the collection area. In some instances where we will be doing con- struction out in an area like the Lime Creek area, on a deferred basis at a later date, even there we will have four or five additional years of actual collection data records before we design these extended parts of the project. I just point that out so that we don't have a mist~<en impression that we may be de- signing a collection system with very meager data. I The Fryingpan-Arkansas Tunnel extends under the Continental Divide, the west portal being on the river at this point (again pointing). The water will be collected and brought by gravity to a common point from the north and from the south where it will go under the Con- tinental Divide. These capacities vary at the extremities from about 30 cubic feet per second until, at the time you get to the tunnel, they will be in the neighborhood of 300 to 310 cubic feet per second. The capacity of the tunnel is about 900 cubic feet per second. The specifications which we hope to get out
