DG,
I personally have been working on this for 2 years now. And I can tell you everything you have asked has been looked at and quite a bit more as well. This has taken a lot of work by a lot of people to get it to this point.
For many, many years we have asked TU and NMWF for help in addressing the flows being changed on the Juan and the effect it would have. We were told flat out we were a tailwater and to more or less take a hike.
So we started this with help from the Fly Fishing Federation, local businesses and the local fisherman.
It is frustrating to see TU fighting us on this, they simply don't give a damn about this river our the people that use it. this is about an agenda on oil and gas. They have thrown the river under the bus with negitive and false radio ads, newspaper stories, etc.
I was told by the fellow that runs TU national for New Mexico that TU is no longer an angling group. TU is now an enviromental group.
TU has lost touch with the average fisherman
sorry for the rant guys
