CTUIR GIS Program Databases


The purpose of this web site is to share some of the natural resources and GIS data that have been collected by CTUIR and partnering agencies. The CTUIR GIS Program’s mission is to promote and facilitate the collection, maintenance, and beneficial use of geographic information within the tribal government. The GIS Program focuses their efforts on providing training in the use and management of GPS and GIS information, development of reporting and analytical tools as well as cartographic data and products which inform decisions. The GIS Program manages the implementation of ESRI ArcGIS desktop and server software. The website hosts a CTUIR fisheries and a water quality database, which make these data sets available: *Escapement data - Carcass and Redd Surveys for Umatilla and Walla Walla Watersheds (1987 - 2010). *Data collected from 2004 - 2006 at Catherine Creek (Grande Ronde River Basin) and the Upper Grande Ronde River Fish Weir. *Lamprey electroshocking data (1998-2003) and lamprey portable assessment trap data (1997-2007). *PIT tag data collected in the Umatilla and Walla Walla basins. *Steelhead telemetry data collected between 2001 and 2007 (Walla Walla Basin). Umatilla Basin telemetry data from 2009-Present. *Water Temperature data - Over 15 years of Tribal data from the Umatilla, Walla Walla and Grand Ronde Watersheds. *ISCO / Turbidity data - Turbidity, sediment, total suspended solids data that have been collected by CTUIR and the Umatilla TMDL Monitoring Project. *Water Quality Lab data - Parameters include nitrate, nitrite, arsenic and more. These samples were collected by CTUIR and the Umatilla TMDL Monitoring Project. *Interactive Map - Find all of the above data using an interactive map that shows where the data were collected.
