Greetings Tony:
Believe it or not, I’m not as tuned into lumber prices as I am regarding timber/stumpage prices. However, lumber and timber prices are, of course, very closely related.
You may wish to try the following Website to “gauge” lumber prices. Please pay special attention to kiln-dried vs. green prices, thickness (e.g., 4/4, 6/4, 8/4, etc.), grade, retail vs. wholesale, etc. There are of course numerous other Websites out there that publish lumber prices.

Check with your local WI-DNR district forester for local market outlets/buyers.
Best of luck!
