Hi Mike - here's the OHWM info from our flagging effort. Let me know if you have any further questions. 
 
Thanks
Karmen
 
Karmen,
 
The stream’s OHWM was determined by using multiple indicators including (1) the upper 
elevation of alluvial features (e.g., point bars), (2) significant changes in slope, and (3) significant 
changes in vegetation. Specifically, for most of this this site, the OHWM was where the reed 
canarygrass begins to thin out at the first major elevation break on the riverbank.
 
In regards to the missing numbers on the sketch map, I only picked the points seen on the map 
because of their location relative to notable features on the site (i.e. boat ramp, bridge, etc). It's 
strictly for reference purposes and the flags that were omitted from the sketch map can be found 
between the ones that are shown.
 
Let me know if you need anymore info.
 
-Ben

Thanks, Karmen.  Do you have field notes that document the geomorphic and vegetative features 
observed that helped to locate your points?  We may need to extend OHWM downstream and would 
like to assure procedures/observations are similar.  

From your sketch, I notice that several points are not shown (6,7,9,12,14).  Is this something to be 
aware of?  

Jim, Chris, when is the surveyor expected to be on site?

Mike - We completed the OHWM several months back. I've attached our field sketch showing the flag 
locations. We flagged approx. 100' up and down from the outfall pipe. There are 15 blue and white 
striped flags. I imagine the vegetation is much denser now so some of the flags may be difficult for the 
surveyor to locate, but hopefully they can piece it together.   Let me know if you need anything else.
 
 
Thanks
Karmen

Karmen, I am wanting to remember an email or memo documenting your efforts to locate OHWM 
along the mainstem Stillaguamish River, but I cannot locate it.  As I recall, the OHWM was flagged but 
surveying of it was left for a later date.  Can you please re-send your documentation and/or an update 
to it?

Thanks, mw
