I tried to do this with just a hose when installing an oval above ground
pool.
Halfway through the installation I decided to buy a water level that had a
sensor on one end. You set this sensor at the desired height and when you
raise the other end of the hose, when the water raises to the right height
it activates an alarm back in the sensor at the other end of the hose. This
was much more accurate. The water level in the final pool is within 1/4" of
the top of the pool wall all the way around. good enough for me!

I want to make a water-level out of garden hose for levelling the yard
(approx 200' to 300'). I want to make one with a reservoir so as to
minimize the effect of the level jumping up and down as the hose is
moved and distorted.

Most instructions for a 'reservoir level' have you destroying a bucket
by putting a hole in it. Can anybody see a problem with simply letting
one end of the hose hang into the top of the bucket or a barrel? Of
course, all air must be out of the system, as is the case with any
water level. This would be no different than hauling a portion of the
hose over a fence etc, in which case I believe the water level still
works. Thanks.
