Hm"ever, it was rej ected as an option for the reasons given below. (a) Hydrology While the site offers a large poteD-tial storage, the catchment area is only 166 square kilometres and annual runoff is therefore expected to be less than most other sites under consideration. Hence, to create a realistic size recreation lake and minimise variation in size from year to year, it would be desirable to build a lower dam than the site conveniently allows. Unless the maximum size of the lake were only 60 hectares or so, the variati~n in size would be inferior to other sites. Hore berlefit is offeree. by the site in respect of a possible future water supply storage, harnessing most ~f the available runor:;: (French, 1973, found that the dam would rarely fill) but varying considerably in size according to the seaSOD-s.
