Yard Watering Recap

We’re coming out of the dry season, and what a dry season it was. We tied the warmest summer ever (1967) and got the record for the driest summer ever (1910). Even with all that, I’m happy to say that our yard stayed green and I think I used about the minimum amount of water possible to make that happen. Here’s the data from our sprinkler system showing the cumulative gallons used by year:

The 2015 line is especially interesting. It was very hot and dry that summer too, and even with all that water, my yard died. I had the settings really dialed in this year. The key was getting the runtime for each zone set properly and then trusting the Zimmerman algorithm inside OpenSprinkler to automatically adjust those runtimes based on the previous day’s humidity, temp precipitation and the forecasted precipitation. I only overrode it once when we had a streak of weather in the mid-high 90s.

The rain came a little earlier than it has the past two years so I’ve already shut it off, at least for now. The yard looks healthy enough and the weather is wet enough that I doubt I’ll need to run it again.
