I haven't heard of Grand Lake. Do you have a link that references this lake so I can see where it is located?
As someone pointed out, eroding "not quite hard sediment" would not result in cliffs. The non-lithified, water-saturated sediment would slump constantly, forming shallow walls and a wide bed. However, you first need to explain how all that sediment was deposited in the first place. Walt Brown says by the flood.
Hopi Lake at least is likely (not sure about Grand Lake, but both could possibly be the result of post-flood, water-filled basins) and in order to get meanders, you need a relatively flat-lying land surface - that means no Colorado Plateau/uplift, yet.
So okay, you have the meanders set in "not quite hard sediment."
However, when was the Colorado Plateau uplifted? There is up to 7,000 feet difference between rocks found in the canyon and the same rocks found in other parts of the southwest. Additionally, HOW was it uplifted? No matter how much water burst from those dams, they are not going to carve canyons through a 9,000+ ft. mountain of material. The water would go around. Therefore you need to uplift the Plateau before the dam bursts.

In the old earth model as the land rose up the Colorado river would have cut sideways or horizontal across the strata and not downwards as they claim. The meanders would have been impossible using the old earthers models.
I'm sorry, that makes no sense. What do you mean the river would cut sideways and horizontal across the strata? That's actually a better explanation for how floods work. They tend to form wide anastomosing braided stream environments full of gravel and other transported material.
The original poster of this thread is also correct. That is if the waters rapidly left the lakes with out a previous template/channel for the water to follow meanders might not occur, BUT the original poster has an even more diifficult problem explaining how the slow rising land formed meanders.
Slow rising lands NEVER form meanders. Who told you that? The meanders were in place prior to uplift, which is also required for your model, though you failed to touch on that aspect.
Mainstream science can explain the haphazard path of the Colorado River, the meanders, the uplift, how the rocks got there in the first place, how the lowest and oldest rocks in the canyon were formed, etc.
YECs can't. You have a lot more to explain than just meanders.
