Well accoring to this
place anyway
The calculation is so full of crude estimates and averages that I wouldn't place much confidence in it being representative of the lake right now but .... FWIW it seems that NH has an annual average pan rate of 33"/year or 0.09"/day. According to the reference lakes evaporate at 70% of the rate the measurement pans do, so that gives us 0.063"/day or about 15.8 days to evaporate an inch. Funny, "Mee" asked the same question this weekend. When I get some time this weekend I'll see if I can't get a better estimate for this time of year (just for giggles).
