Consideration of return flO1Q from the three project areas led to the
conclusion that usable return flow would be availa:ble only in the Cattle
Creele area. The slopes and locations of the Sopris and Carbondale areas
and the lack of inflow diversion data. led to the assumption that return
flow from these areas would be minor and would probably reappear at points
. too low for rediversion to project lands.
