I sure can't find anything that describes any shot rock removal prior to the gravel injection they're planning. That just doesn't make any sense. If/when that gravel ever gets flushed downstream again [during severe high-flow conditions, like in 2006], they'll still have the shot rock preventing spawning grounds again?
Although, Pasternack's report states "Specifically, the massive amount of undesirable shot rock debris located there (~170,000 yds3) should be removed off site and replaced with ~100,000 yds3of suitable rounded river gravel, to be placed by rational design using the Spawning HabitatIntegrated Rehabilitation Approach of Wheaton et al"
But, I can't see where anything says they will really do that.
