George,
You are correct that I am in the Post Oak Savannah. The soil is clay with a sand covering of about 3". Great for water runoff.During the construction of the new pond, we uncovered several large boulders which are currently stacked along one side for seating and visual effects. What kind of rocks would I need to bring in for SMB to spawn? I did lay some stones (the type used on the exterior of strip retail building you see around here) at a couplpe of spots at 4' depth.
I fly fish my pond quite a bit. Would love to get a decent size HSB on the end of a 3wt rod. Do you have any experience with YP at your place?
