Rochelle, FYI Cooper and Tye are not the same grade in difficulty. Similar but Tye is a step up in my opinion.
Also, Tye is not low at all now. IT's crankin. Don't let Christian (a TT Master) bait you. There is a small sapling tree at the Takeout Bridge (upstream from Alpine). That tree is a good spot to guage the level off of. IF the water is at the saplings base, then the run is MED. IF its 8-10" below then its low, but still doable. When the base of the tree is under water and water is above base then start thinkin MED to MED HIGH to HIGH depending on how far water is above base. EH< 5" above base and some very capable paddlers begin portaging Paranoia.
Rochelle, you are a crazy riverboarder. I'd rather not recomment this run for you, but that will only inspire you further, so check things out. You totally could do it, but then again it's not something I'd suggest do to the gradient of some drops and the rocks you will hit in some of the bouldergardens. Hope this helps....
Not trying kill your trip Christian! Fire it UP!
