Back fill of stream. What's it going to take?

[brittsnbirds]

Enjoyed my time last week at BSSP.  Didn't know it was free fishing for kids but that didn't pose a problem.  Biggest problem was trying to negotiate the "new" stream after all the flooding this past winter/spring.  Pretty bad when you can walk to the far side of the bank at the island (that isn't there).  As well as walk all the way to the dam at the long gone stripping hole.  The gravel backfill is really bad and will only get worse.  

 

Anyone have any insight about what the plans are to dredge if there are any?  This stream is in really bad shape from arch bridge up to spring.
