It shows that storage so far in sight, and for whichcontrolling dams are either under construction or sites fullysurveyed and contract plans under way are:— MaximumPossible Basin. Area. Depth.

This represents a maximum possible reserve for each ofthese lakes of practically 56 billions cubic feet, or a total of168 billions cubic feet of water, which instead of rushing towaste, would be pent, up in these reservoirs and graduallylet out during the low period. Taking the low period at 150 days between October andMarch, it will then be possible to augment ultimately thelow water flow at Ottawa for that period by 10,000 to 12,000cubic feet per second. It can be seen, therefore, what im-mense benefits will be derived from these reservoirs. Theirbeneficial effect is admirably resumed in Mr. Coutlees re-port, as follows:— I St. They will improve the potability of the water. 2nd. They will increase the depth for navigation. 3rd. They will increase and steady the flow for powerprodu
