GCDAMP History PAGE
 The dashboard idea is nothing new, and is utilized by companies 

and businesses all the time

 How nice would it be to find out the mass sediment balance, the 

current science trips/projects, the lake levels, the snowpack, the 

latest news stories, the status of the guiding documents, 

hydropower unit availability, rafting, fishing info??? 

 (With much of the inputs automated)

 The Dashboard can automatically search out, and pull information from 

existing web-sites and trusted reports and display the information/ 

graphs on one page. (front and back) 

 One click of the button and bam... all the latest and greatest 

GCDAMP related info on a printable page.

 *Still in protocol form, but you get the idea...
