[White-water] Sandy gauge at Brightwood

[Gordon Taylor]

Greetings:

Below is the response of USGS to my inquiry regarding the discrepancy 
between the gauges on the Sandy at Brightwood and Below the Bull Run.  In 
short, the new gauge at Brightwood is not yet fully calibrated, and the 
gauge below the Bull Run may affected by silt from the removal of Marmot 
Dam.

| Hello Gordon,
|
| You are right, the relationship between the two sites 14136500 & 14142500
| is not correct. The upper site, 14136500 Sandy River below Salmon River,
| near Brightwood is a new gage with few measurements and the rating needs
| further development after more measurements are made.  The lower site
| 14142500 Sandy River below Bull Run could now be affected by the removal 
of
| Marmot Dam.
|
| I am forwarding this email  to our field office supervisor and to our data
| manager as well as to the technician who maintains these sites. Until then
| I will see if we can't get a statement of some sort placed at the top of
| the web page explaining the discrepancy.

| Greetings:
|
| On the Sandy River, your gauge at Brightwood reads 1,200 cfs and your 
gauge
| below the Bull Run River reads 898 cfs.  This relationship is of course 
not
| possible.  Is the Brightwood gauge not reading correctly?
