One of my favorite stretches of bass and trout water also happens to be absolutely LOADED with leeches. That generally means that a nice black rabbit strip streamer will take some good fish. You just need to be there at the right time. I went at totally the wrong time the other day, which is why I was catching nothing but sunfish instead of big smallmouth for a while.
Eventually, while I was swinging the leech through some very deep water, I got a strong pull. It ended up being a big powerful holdover rainbow, also the best fish of the outing.
Hoping to get the smallmouth figured out I tried various topwater patterns. I only caught one, on a Morrish Mouse. Clearly today was just not going to be a big fish day. At times it is safe to leave early.
