As a matter of fact I've been told by close relatives of the owners of deer creek ranch that there
are some german brown trout that hide out in some of the pools along deer creek (mazatazal).
although I also recognize the fact that the creek does seem completely dry at times. I was told
by one of the old-timers who also mentioned that way back when all those creeks in that area
ran year round and that it has only been in the last 30 years or so that they started drying up. I would tend to believe that, seeing how the deer creek ranch had owned water rights to the creek
until a few years ago. still i dont know if the stories hold any water.

though you have to assume
if the creeks once ran year round its possible they were once stocked or had native species.
