You're right -- we didn't see those on rocks or sand, only on wood.
I can't imagine a fish being able to deposit eggs like that... must be some type of crawling thing. Anyone know how crayfish lay eggs? I doubt it would be snails, since I've never seen any big snails in Wazee. The egg blob is about 1/2" wide so it probably isn't a bug either. There are some rather long, continuous groups of these things, so it's not a small creature.
Then again, maybe it's some type of colonial growth.

crayfish are like lobster - they lay eggs under their tail and carry them around...
have no idea what does these...

A bunch of pals and I went to Wazee last Sunday, this time at the Sherwood Forest (north-east) boat launch. I specifically brought the camera with 100mm macro lens to search for the "egg sacs". After searching for over an hour in the shallows, I couldn't find any evidence of the sacs. All the submerged wood in this area is covered by something else (see below), and there are a lot more fish in this area, so maybe it's not a suitable location.
On the second dive we scootered around the lake. I did spot some egg sacs on the top branches of some trees near the south boat launch, but didn't have the camera with me.
Here are a couple photos of the stuff that covers submerged wood on the Sherwood side. This is on the platform:

I couldn't see clearly enough with my mask to see if they were moving, but they look like they could be a colonial animal (they look similar to barnacle gills) rather than a plant. If anyone has a video camera with macro capability, it would be nice to see them in action.
