How Grows the Milfoil This Year?

Friday, May 29th, 2009

On Tuesday, May 26th, I joined the dive crew for a thorough survey of the lake.  We spent about two hours circumnavigating the lake on the pontoon boat, occasionally with a diver in the water for closer inspection.

This year, even though the ice went out mid April as usual, we had a week or two of unusually warm weather in early May.  Consequently the milfoil seems to have gotten an early start.  During the winter it “lies down” and goes dormant.  In the spring when the sunlight reaches it on the bottom it begins to grow.

It is hard to get a good photo of milfoil from above the surface. For that matter it is not easy underwater either. In a future post I will try to include some underwater shots.

As usual the milfoil has some surprises for us. In some locations where we have wiped out whole patches using bottom bottom barriers or suction harvesting the milfoil has not returned, and the local pondweed and other species are returning. In others the milfoil has taken root again. The purpose if today’s tour is to gather information so that we can plan this summer’s activities intelligently.

The Divers Return

The divers began work on May 19th this year. Most of their first week was involved with getting equipment in good repair and ready for the season.

This year we have some new faces on the crew.  We have lost Ira, our crew chief for the past few years.  A.J. Beard, pictured on the left above, will be taking over Ira’s duties.  Toby and Leon will be diving this year – each has previously worked on the crew in past years as the boat person.  I will intorduce them to you at greater length in the future.
