( a ) during the period from April to September inclusive the water level of the Upper Lough shall not, as far as reasonably preventable, exceed a level of 154.0 feet above O. D., and when and as often during that period it has risen to 153.0 feet above O. D., is rising, and is in the opinion of the Ministry's Engineer or the Board's Engineer likely to rise above 154.0 feet above O. D., the water level of the Lower Lough, if above 151.5 feet above O. D., shall as rapidly as reasonably practicable be reduced by the Board to such level not lower than 151.5 feet above O. D., as may be required by the Ministry's Engineer for the purpose of ensuring that the water level of the Upper Lough may be prevented from rising above, or be brought down to, 154.0 feet above O. D., PROVIDED THAT when the water level of the Upper Lough has reached its maximum and has fallen to 154.0 feet above O. D., or has reached a maximum not in excess of 154.0 feet above O. D., and is falling, the water level of the Lower Lough shall be permitted to rise to such level not exceeding 152.0 feet above O. D., as shall, in the opinion of the Ministry's Engineer, be reasonable;
