After completing the Dam 3 Challenge (D3), I got interested in dams in Washington State and ended up doing some dam research. Did you know that Washington State has over 800 dams? These dams range from flood and flow control to hydroelectric producers. Washington also has the largest hydroelectric producing dam in the country which is the Grand Coulee Dam. In 2011, Washington State was the leading producer of electricity from hydroelectric sources and produced 29% of the country’s net electricity generation.
Enough of the stats, lets get down to the puzzle. This cache is obviously about dams in Washington State. The final cache coordinates are:
N 47 29.Boundary, Long Lake, Wanapum (minus 2)
W 122 13.La Grande, Howard Hanson, The Dalles
You may have to park a bit up the road and walk back to the cache. Enjoy!

CONGRATS TO TERRIBLE T'S FOR THE SOLO FTF!
This is one of 54 puzzle caches spelling out "WSGA" in honor of the 10th anniversary of Washington State Geocaching Association.
