1. There are no other effects of the dam which will prevent the native
fish of the river from using the new sandbars below the dam.
--this could be an assumption but can’t be inferred
2. The flood caused by massively releasing water from the dam will be
like a natural flood in every major respect.--if water from dam can help recreate the sand bars, flood will also be same as natural flood
3. The size of a sandbar on a river always stays the same or increases
after a flood.
-- size of sandbar is not in discussion
4. Any other dams upriver from the Glen Canyon dam must also release
enough water to cause a flood in order for the flood from the Glen
Canyon dam to be successful.
--Other dams are not concerned
5. The dam does not prevent the flow of sediments from upriver needed
to replenish the sediments that inevitably wash downstream over time.
-- May be true but no information from passage.
