Why does my lawn have a perfect brown arc around a sprinkler?
Short answer: A recognizable geometric dry pattern can reveal where a sprinkler’s actual coverage ends — the brown arc is the edge of the spray, and everything beyond it is getting no water from that head.
When a head’s spray stops short — because the nozzle is wrong for the distance, the pressure is low, the head is blocked by grass, or the head is a rotor that was set to a shorter radius — the lawn inside the spray stays green and the lawn just outside it dries out in a clean arc. The shape is the clue: a perfect arc means a spray pattern, not a disease or a pest, which would look ragged and irregular.
We run the zone and watch where the water actually lands, then check the nozzle, the pressure at the head, and whether grass or a shrub is blocking the spray. Fixing the arc usually means a nozzle change, a pressure fix, or moving the head so its pattern covers the dry ground.
What we check in New Caney
This is a common call in New Caney, and it is the kind of problem we test in the yard instead of guessing at from the driveway. We run the system, watch how the water is actually moving, and check the parts that cause this — before anything gets replaced. That is the same approach in the full Sprinkler Installation service page.

Frequently asked questions
Could a brown arc be a disease?
Disease and pests usually make irregular patches, not a clean geometric arc centered on a sprinkler head. A perfect arc that matches a spray pattern is almost always coverage.
Why would the spray stop short all of a sudden?
A clogged nozzle, a drop in pressure on that zone, or grass growing up around the head can all shorten the throw. Any of those can turn a head that used to reach into one that falls short.
