As has already been stated, it's not only reservoirs which store and provide our water, the main issue in much of the drought area is the underqround aquifers which serve large parts of the country and are at very low levels. These aquifers rely on winter rains to recharge them, since much of the summer rain is lost to plant growth, evaporation etc. Recharging takes many weeks/months after rain has fallen so the less water taken from these aquifers right now, the better and that's why the hosepipe ban is still important.
