NOAA - NWS Hydrographic Data

Adventurer's Project's website remains a "works in progress" and is not published yet.  But I continue to add things to it.  The most recent thing is that I found how to get access to data submitted from five Hydrographic charts from the NOAA - National Weather Service.  I'm linking them for the following stations:

Ohio River at Marietta Pump House

Duck Creek Near Whipple (approx 320ft W of the Whipple Section between Pts. 11 & 12)

Duck Creek at Macksburg

Little Muskingum (River) at Bloomfield [3.8mi NE of Road Fork Section, Point 26 (07/2011 Map & Guide)]

-  Muskingum River at Beverly [7.2mi S of Whipple Section, Pt. 22 (10/2010 map & guide]

The Marietta Pump House give a good baseline understanding of what's going on in the area as far as water level is concerned.  The station near Whipple might determine in BT's clockwise direction if Whipple 13 is under water?

  The station at Macksburg is roughly at 672ft elevation.  The ODNR Dam at Whipple 15 is south of that at 644ft.  They are approximately 6.82 miles apart from each other.  What level would the water on the Duck Creek on Macksburg's hydrograph have to be in order to flood over the ONDR dam near Whipple 15 that is only 3 feet above normal the level of the creek in that location?  If we can determine this, then it could alert the hikers traveling in the counter clockwise direction that they'll be on "Dry Boot By-pass," instead of crossing the Duck Creek near Whipple 15 on the concrete ODNR dam.

The Little Muskingum (River) at Bloomfield station could alert hikers that the Road Fork Section near the Ring Mill might be under water?  For out of town hikers, this is the kind of information that they would need in order to know whether they should drive at distance to traverse the area.  And the Muskingum River at Beverly's levels might somehow indicate the creek and stream levels between Whipple 21 - 23.  This area is on higher terrain, but those creeks and streams could bloat?  And one of the roads there can have large holes in it?

I have the flood stage data for these stations.  But in order to make it a custom fit for these sections, I think that digital photographs are the way to go.  They have a time stamp embedded in them that can be accessed with the stock Windows Explorer in Microsoft Windows.  If I could roam the area on a very rainy week, take pictures then compare their times to the ones stated in the hydrographs, then I may be able to say based on the Duck Creek in Macksburg's normal level (for instance), that if the hydrograph shows the creek at a certain level, then the Dry Boot By-pass is definitely in effect and we can spare the hiker from having to hike 2.9 miles down to find out, then 2.9 miles back.
