Bill - Thank you very much for the honest assessment. What I've gathered from the responses to my post and from conversations in other threads, you're absolutely correct that this pond/lake could very well be a money pit if we let it. We love the house, so selling won't be an option!

I went out and kayaked last night and paid attention to water clarity. I'd say I could only see the tip of the paddle at 2.5'. So visibility is 6' in spring/early summer and 2.5' now. From your response, maybe less visibility at this time of year is actually a good thing.

I think I'll check with the pond management guy to see if he has the equipment to do the pH & DO testing. We don't need the full blown lake assessment but maybe he could get us info on those two readings.

Thanks again everyone for taking such an interest in our little lake!
