From email from the Douglas County Water Resource Authority:
Memorial Day usually announces the beginning of our summer season, and with all of this spring’s rain and snow, your lawn may be greening up nicely. This may be a good time to measure how much water your sprinkler system is actually putting on your grass. Use “catch cups” to find out how much water your sprinkler system is putting on your yard. If you’re not sure exactly how to do that, here’s the link to the two-minute “how-to” video: http://www.youtube.com/watch?v=MXHhwMZ2KO0. “It’s so easy, a kid can do it!”
