Paw Paw Lake (Coloma / Watervliet) – Zebra MusseL Invasion

For those who did not get outside today, it was actually quite pleasant. At Forrest beach (Paw Paw Lake, Watervliet side) it was in the mid 40’s, no wind and not even drizzling. The water was just a bit cool to the touch, still soft and with good clarity.

The lake bottom appears to have a thick silty sand build up everywhere with no patterns to indicate where it’s coming from. Did not notice any weeds but did come across very nice patches of green vegetation. The most notable finding and change from last year, other than the sand, was the number and quantity of zebra mussels.

On the bottom, if it’s not sand or vegetation it has a significant buildup of mussels. Everything from tires, boulders, tree parts, and even very small exposed parts of small rocks are all covered with a thick covering of mussels. Did not see any cray fish and the few clams I did locate were barely alive and all covered in mussels.

After hearing some motor noise nearby, I surfaced to see a fast moving speed boat whizzing by a dive flag. No chance to get numbers or name. So obviously boaters / fishermen are out and about.  Interesting how many inland boaters do not know the requirement to keep away from a divers flag.

Small clump of zebra mussles. There are over 60 individual mussles in this clump.

Thirsty Thursday Dives (Niles, Mi)

The nice thing about belonging to a dive club is you can more often than not find a buddy to go diving with you.  Other opportunities to dive include the weekly  “Thirsty Thursday”  dive after 5:00.

During the last month of summer and early fall, the Saint Joseph river, as it wanders thru and around Niles, Michigan,  begins to clear up. That means the visibility increases , the river current moderates and the water temperature is suitable for wet suits.

One of the draws to diving the river  is looking for bottles, some of which can be of significant value to some collectors. Divers that do this sort of diving are called “grubbers” as they dig around in the muck looking for treasures made of glass.

Here are some of the finds:

A littler bit of everything
and more
good bit of glass today
and after cleaning- many are “keepers”

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Golf Balls Galore

Today was an interesting day as I had the opportunity to do a little underwater work at a local golf course. Not too technical, just an intake pipe inspection, a bit of cleaning vegetation off intake screens and clearing the intake flow path. Cut and removed some  tree root balls from a suction pit and did some video of several pump intake pipes. Here are a few u/w shots of what you might see under the water in golf course ponds.
