USGS 01653600 Piscataway Creek gauge height at 7:30AM: 3.09 feet. This is why we compare the data from Piscataway Creek with the rain gauge: the rain gauge measures 0.01 inches of precipitation with no evidence of frost on the gauge. Experience has taught me, during the last year, that it requires a certain amount of effort on behalf of Mother Nature to put 0.01 inches of rain in the gauge. But I noticed absolutely nothing of rain last night. The data from both Piscataway Creek graphs shows a noticeable upward bump for yesterday evening and yesterday I was hard at work composing music with my headphones on all afternoon and evening, so I would not have noticed the rain.
