Will do Scott. Thanks for the info. I'll be back again next week. It's just weird seeing "brown" like this. I'm guessing it has to do with the drainage out of the woods, and off the road. I've seen the water draining in off the road before. It's just a dirt and rock road, but it's been in use for over 100 yrs. It used to be a county road. We have the foundation from a one room schoolhouse back near the pond. Pictures of kids and teacher standing in front of it from 1904. It probably saw quite a bit of traffic at one time.
Looks like this now.

12 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs)
I think that's about all I should put in my little pond.
