WOW guys!! Talk about some pigs...great pics.
I have never seen a crawdad in the lake, but that doesn't mean anything, since I have never really looked for them. The inlet comes in on a pretty steep section, and the lake drops off quickly along that edge.
I tied up some Olive Brown DDH Leeches this winter, which are quite similar to a bugger. I am familiar with Chan and Rowley, so I will do some more reading on their strategies.
Here's a pic of the lake - (Northeast WA)
