Snowfall in the area (the Tetons are part of the Greater Yellowstone Ecosystem) is 150% of normal, but the moisture content of that snow is 200% of normal. That is where all this water is coming from.
I assumed the cruiseboat there would be having an issue with that bridge, but had forgotten about the electrical boxes in the marina. Yellowstone does have a very nice floating dock system, but there is a limit on how far up that can go without damage due to the connection to their "seawall" on the shore side.
All the tributaries in the area are running full (some over the banks). The Snake River (running south of Yellowstone) has a lot of dams and reservoirs that have been drained down in anticipation of the massive runoff (that was our situation in Colter Bay when we first arrived - we are now above 90% capacity and doing fine); Yellowstone has no controlling dam, so as that lake overfills, there is a LOT of water going down the Yellowstone River. I would anticipate debris in the lake there to be a concern for all boaters.
For Dave, unless you were going to spend all your time on the lake in Yellowstone, I don't think you'll find the rest of that HUGE park to be affected by this, other than some trails closed due to snow/mud. Further south in the Tetons, everything is running as normal, although our tributaries south of the dam are causing high/fast water on the Snake... the three-hour scenic float trips (rafts) are taking about two hours. :wink: The white water raft rides are actually a little less "thrilling" due to the high water - but it will still take your breath away. Here's a shot of our family rafting while our daughter and son-in-law were here the week of Father's Day...
The floating docks in our marina in the Tetons have required a lot of repair after the tough winter (welders are still working on some parts), but because they do not have a hard attachment to the shore (like Yellowstone), they won't be damaged by high water. Transient slips here, however, are much tougher to come by, where Yellowstone generally has vacant transient slips.
If you're "land traveling" either park, there should be no issue. As stated previously, the oil leak was way downriver from the park, although the media has sensationalized the fact that it is the Yellowstone River (and many assume that IS all in the park). The Yellowstone River is one of the longest undammed rivers in the US.
So, come on down to two of the most amazing National Parks in the country... it's only 23 miles from the south entrance of Yellowstone Park to the Colter Bay Marina in Grand Teton National Park.
Best wishes,
