Five in the morning, mid-July, and the only wet thing in Mason County is a lawn under a running zone. Olson Irrigation Inc builds and looks after those systems — heads set and adjusted, lines run, spring start-ups, mid-season repairs, and fall blow-outs before frost gets into the pipe. Dune sand will not hold water, so coverage has to be even and the timing early, or half of it goes back to the sky before breakfast. Set up properly, a yard comes up green all at once instead of in patches, and keeps its color through the dry stretch of August. Irrigation and lawn watering work for Ludington, Hamlin Lake, Scottville and the townships nearby.
