Jay, there are a ton of primitive campsites next to streams and lakes. The problem being that they should of been built farther away to prevent water contamination. The ones I know of primarily exist in Wilderness areas such as the Flat Tops, Eagles Nest and so on. I still use them because its a lot less damaging to use a preexisting camping spot than building a new one in my opinion. I am just careful about what I do with my grey water as not to contaminate anything. Were you looking for any area in particular?
