Another study was made to detcrrrQn8 t~9 amount Gf water divert8d under

direct flow decrees during the winteI' period, that could be stored in Caddoa

reservoir without conflict with present administrative procedure, Cnly the

water diverted during the months of December. January, and February, when

,
the Colorado canal was diverting water for storage in Lake Meredith, and/or

when there was an obvious surplus supply at Lamar, was considered as direct

flow water storable in Caddoa. By this process it is esti~ated that the follow-

ing amounts of water, diverted during the three-months winter period, could

have been legally stored in Caddoa reservoir:
