Percival Creek Streamflow Data - Located on the South Puget Sound Community College Campus

N 47° 01' 21" W 122° 55' 56"

TC Designation 23b

This site will be terminated in 2016 due to funding reductions

Site History:  This location was selected for multiple reasons and has been moved because of multiple incidents of vandalism over its 20 year history.  It now lies within the South Puget Sound Community College campus and provides students with learning opportunities in hydrology as well as providing 15 minute streamflow data for the Water Resources Program and our Interlocal municipal partners (Tumwater, Olympia and Lacey).

This site is located in Percival Creek which contributes to the Lower Deschutes/Capitol Lake basin.  It also joins with Black Ditch and other urban tributaries below the campus to for a combined output to the Capitol Lake system.  The site was moved to its current location in 2008 after it was damaged by vandals in its prior locations on or near the main stem of the combined flow reach near Cooper Point road.  Before that it was located further downstream near a pedestrian bridge crossing but was stolen from that site in 2003.  Some data below in historical section reflects data collected over the full period of data collection since1988 but it is from multiple locations within the drainage and may not be correlative to other locations because of slope, geology, and changing contribution areas.  The site has been stable its current location.

Note: The Water Year and the Calendar Year are not the same. The Water Year (WY) begins on October 1st of the preceding Calendar Year. It is a hydrologic measure not a calendar measure.

 For example: Water Year 2012 begins in October 2011 and also includes November and December 2011 and would also include January through September of 2012.
