I had never heard of it until I checked out a book at the public library in Salem ("Fishing the Great Northwest"). The easiest way to get there is to go to the town of St. Paul, and turn West on blanchet road, which is right downtown near the metal fabrication shop. Follow the road for about 4-5 miles (even though it says "dead end") to the very end, and you are there. There are usually at least 5-10 plunkers there, but they are for the most part generous with the space.
What is this alagae that everyone is talking about? Is it that long, stringy moss? If so, it is terrlible at Wheatland...I had an awfull time plunking there yesterday as it was constantly fouling the line and spin-glo.
