I would think they have barriers up to keep that from happening. 

Went by Sunday - no silt barriers. Everything was tapered off towards the river.

Not the first time a contractor didn't use proper run off control......unfortunately

I was up there for last day in the park yesterday.  Did not make it to Baptist, but the construction at the lower end of the park around the lagoons has started.  KCI construction had silt barriers up around all of their perimeter.

Fishing sucked.

Wish they would use silt fences, but they're only required for construction sites an acre or larger. I do see  a "floating turbidity curtain" on the plan sheets for erosion and sediment control.

 

 

[jdmidwest]

That should apply there. 

And the sensitive nature of the area, Ozark Natural Scenic Riverway, and other factors should mandate it. 

But, if you look at the pics, they are not disturbing soil, just gravel and concrete.  Instream gravel permits are a dime a dozen and do not require any barriers as long as they stay away from water.

They are returning the area to a gravel bar. Why would a silt fence be required? The park service even gave them a permit (waiver).

Mostly sand and gravel near the water.  Won't get to check it out till later this month but no worries.

Yep The contractors have done a great job so far not muddying up the river. The sub contractors are local and dont want to screw it up.

They should have just left things alone to begin with.  Maybe just re-establish a riparian corridor. Design for the original work should have considered high flows, but that's engineers for you.

Hopefully there's no big rain events in the next 90 days!  There's a lot of fine material in that construction debris that could easily wash into the river.  There's already too many degraded areas on this stretch of river with too much silt/fine material  from human disturbance in the watershed.  They could do this work in a month, or less, if they really wanted to.
