Providing interpretive education on wetlands and wildlife, panoramic views, water quality, weather, natural resource management, trails, bird watching, recreation, exhibits, displays and an eagles nest, Jackson Bottom Wetlands Preserve is a treasure of the Hillsboro community.
The Tualatin River drains an area of 712 square miles. The river generally flows in easterly direction from its headwaters in the Coast Range to its confluence with the Willamette River. The river is approximately 83 miles long, with several tributaries, including Scoggins, Gales, Dairy, Rock and Fanno Creeks.
Jackson Bottom Wetlands Preserve is located in the 3000-acre Jackson Bottom floodplain of the Tualatin River. Jackson Bottom is located just downriver of the Dairy Creek confluence with the Tualatin. In winter and spring, as a result of significant precipitation events, the Tualatin River overflows onto large areas of the Preserve. Most of the Preserve is at 128-130 feet MSL (above Mean Sea Level). The Tualatin River water quality monitoring site at the Preserve is at River Mile (RM) 44.4. (RM 0 is at the confluence with the Willamette River.)
