Green River/Howard Hanson Dam

Storms in January 2009 weakened the Howard Hanson Dam, causing the U.S. Army Corps of Engineers to restrict the water level of the reservoir behind it.  Their inability to store as much water as in the past, forcing them to release water during very signficant "Pineapple Express" storms increased the risk of flooding in the Green River Valley for the last few years.

 

Repairs have now been made at the dam, and it is operating at full capacity again for the 2011-2012 flood season.

 

Even with full working capacity at the dam, there is always some flood risk here in the Green River Valley as well as other areas near bodies of water.
