Box 1240 Leadville, Colorado May 19, 1977 This letter is to further explain the necessity for haste in the acquistion of a permit to allow the production of bedding material for the Mt. Elbert Conduit required by the specifications of the Bureau of Reclamation. 80461 The location of the project is near Leadville, Colorado. The ele- vation of the project is approximately 10,000 feet above sea level, which creates very short working seasons of approximately five months per year due to freezing conditions. The determination of the five month working season is derived from the weather charts of record for this area. The entire project is affected by the freezing con- ditions but particularly the compacting of the bedding material. It is necessary to add water to the bedding material as it is placed and if the temperature is below freezing it makes it impossible to com- pact the bedding material to the specified density. The contract time allowed by the Bureau of Reclamation is 3 years, which allows Kasler-Woods 15 months of working time to complete the project. The construction of Mt. Elbert conduit will furnish one of the final links required to complete the collection and conveyance system which will divert western slope water to the Arkansas River basin of eastern Colorado. Halfmoon diversion adds east slope water to the system. The water from this system will be used for municipal supply, irrigation, and power production. The work is located south and west of Leadville, Colorado, in Lake County.
