So back to the venue from yesterday, armed with traces this time.
The mill pool ... zero bites ... no following perch ... no pike attacks.
Tried the nymph ... absolutely nothing which I found very odd as there had to be at least dace around.
So back into the woods to look for rising fish as the sun came out but again ... totally dead.
Figuring there had to be fish in that stream I tried the nymph again and behold after a lot of work one little dace.
Maybe the fish are put-off by the extensive manure spraying of the farmers. 
Always hate when the surface of the water begins to foam...
