Encouraging numbers, trends...

Compared to 2006, the herring migration [to date] has been different in several ways.

I say to date, however, because you really can't make an accurate assessment until it's all done, but these points are clear:
  1. The quantity is greater than last year: in 2006 the highest single 10 minute count was 60 herring [or 360/hour] and so far this year we've had a high count of 109 [or 654/hour].
  2. Many other counts are higher although not as strong as that peak number.
  3. The trend by day this year is quite different then 2006, when there was a noticeable drop-off after the first week. Except for a few relatively lighter days, this year it's been pretty steady from the beginning.
  4. The mornings have been very light, with most of the herring passing in mid to late afternoon, from 2:00 to 6:00 pm.
We have only last year to compare to, so it's hard interpret these trends and to make any meaningful predictions, except that in general terms, things look somewhat improved over 2006.

The whole program has been running quite smoothly and our counters have been doing a great job!!

Having them post their counts directly to their online spreadsheets saves a lot of work all around and allows us to post these timely observations.
