How far downland is your property from the area where the chicken

about 350 ft.

do you know if the poultry farm just started spreading the goods two summers ago or have they been doing this for some

10 + years

LoopTech do you have surface scums or films that accumulate on the down wind shores? OR is the water a uniform green as you go deeper into it?.

No scum at all.. The water appears to uniform green

The color looks to me to be too deep green, assuming the camera captured the true color

It is a deep green color ( Pictures were taken with a 6 Mega Pixel camera)
