with a low of 20 degrees and high of 50 yesterday the maple sap ran at the highest volume of the year. The vacuum exchanger at Harmons was tripping every 25 seconds (highest ever) and the 1.5″ sap line was full coming off the hill. The new booster in the west section was filled with sap since it was running at maximum flow. The sap ran hard for about 6 hours and then fell off as the pressure dropped. The frost is almost out of the ground. I was able to drive a pipe into the ground that was needed to hold up the new slough 3/4 line. I then went down to the pickup tanks and helped Marlo Bauer pickup a tanker of 3000 gallons at 1pm. It didn’t freeze overnight and the high today is in the mid sixties with a strong south wind. Jim turned off the vacuum last night about 8 and turned it back on at 10am. The sap is running at a slower rate today but with the vacuum we still should be able to get a good amount of sap.
