To cover 1,000 sq. ft of lawn and apply enough
water to moisten 1" deep,
it will take 83 cubic feet of water.

It will take 624 gallons of water to cover
1,000 square feet of lawn
with an inch of water.

One cubit foot of water is equal to 7.48 gallons of water.

Water your lawn with occasional deep waterings
to encourage grass roots to
penetrate deeply into the soil.

Roots that grow deep into the soil are more
drought resistant and cold hardy. Avoid frequent shallow waterings as
this only leads to shallow rooting.

Mow your grass higher than usual or don't mow at all
during a drought. Dried grass foliage
helps insulate the crowns so they will retain more moisture.
