constructed and maintained so that they would leak except along

reaches that were very close to the river. In these areas, it was
assumed that the canal would be earth-lined to keep losses to a

minimum.

Each of the four recharge facilities were designed to provide the

same amount of water, on an average annual basis, to the project

lands (at the farm) as Narrows Reservoir would. Thus, recharge area I

would provide 2,540 acre-feet to the lands under the Fort Morgan Canal;

recharge area II would provide 4,590 acre~eet to the lands under the

canals with the remai~e~,~~afged through spreading areas or shallow

ponds. Losses were esti~d to be 60 acre-feet, 810 acre-feet, 700 acre-

feet, and 4,500 acre-feet, respectively, for each of the four areas.

Diversion requirements, then, would be 2,600 acre-feet, 5,400 acre-feet,

14,500 acre-feet, and 6,900 acre-feet, respectively, for each area.

The recharge facilities in the test areas were sized to be able to
recharge the above quantities of water in a 30-day period. This time
period was chosen to represent a worst case condition regarding the
availability of the required water. Using an infiltration rate of
