(2) What makes a basin more suitable to a weather modification operation than another? Tests were devised to answer the first question. Utilizing a target-control concept the tests indicate that six years or less would be sufficient to detect a 10% increase in seasonal runoff for about one third of all gaged basins in the Upper Colorado River Basin. Suitability criteria for both large water gain and rapid evaluation have been developed. Their application to the Upper Colorado River Basin point to three optimal zones of approximately 30 mile radius, centered around Red Mountain (half way between Silverton and Ouray,) Marble (or more precisely half way between Marble and Crested Butte) and Vail.technical reportsengCopyright and other restrictions may apply.
