Data were collected from September 1989 to September 1992 on an irregular basis to sample both baseflow periods and storm events across seasons of the year. Stage height was read from staff plates permanently located at several location in the mainstem channel and in a small back channel; water table elevations were measured with a weighted measuring tape with a visible signal when the tape touched the water in the well. hydrology storms disturbance physical processes hydrologic processes streamflow modeling inorganic nutrients groundwater hyporheic zone forests aquatic ecosystems streams LTER controlled vocabulary peak flows low flows Andrews Experimental Forest site thesaurus disturbance inorganic nutrients LTER core research areas See WELLLIST.TXT for basic information describing each well and locations of each measurement point included in this data set.

Data were used to parameterize a groundwater flow model (MODFLOW) which was then used to estimate fluxes of hyporheic water and groundwater through the study site. Water flux estimates were combined with water chemistry data (see CF004) to estimate nitrogen fluxes.

Water depths were only measured from observation wells. Casings for observation wells were made from PVC pipe and screened by drilling 0.32 cm diameter holes into the bottom 50 cm of each PVC pipe, at an approximate density of 1 hole/cm2. All wells were driven by hand because the study site had no road access. Large cobbles and boulders throughout the study site hindered well placement so that the deepest wells penetrated only 2.5 m below the ground surface. Wherever possible, wells were placed in holes driven at least 50 cm below the surface of the water table at summer baseflow. Holes were back filled with the soil originally removed and, if necessary, additional fill was taken from nearby soil pits or recent root-throw pits. Following installation of the wells, back fill was washed and entrained sediments were removed from the well casing by repeated pumping. A single transect of wells was established during late summer in 1989 as a pilot study. Additional transects of wells were installed during the summer of 1990 and an additional 18 wells were established on, and adjacent to, the gravel bar during 1991 and 1992. Water depths and water table elevations: Water depths measured from the well network were converted to elevation referenced to an arbitrary bench mark. All wells were surveyed and water table elevations were found by subtracting the depth to the free water (measured from the well head) from the surveyed elevation of the well head. Water depths were measured using a home-made depth sound consisting of a analog multi-meter and wire leads attached to a measuring tape. The multi-meter was set to record resistance. The tip of the wire leads were exposed and when dipped in water, the change in resistance would cause the multi-meter=s needle to jump. Measurement precision was excellent (" 1 mm). Overall, accuracy was somewhat less. Repeated surveys of well head heights had a precision of (" 1 cm). Further, the measuring tape with its attached wires would not hang perfectly straight nor were all wells exactly vertical. Expected accuracy of measurements is (" 2 cm). The McRae Creek study site was about 200 m long and 80 m wide and was located along the eastern bank of an unconstrained stream reach (see Figure). A complex of landforms is present within the study site, including a recently formed gravel bar, older floodplain surfaces, and terraces. Sediment of the gravel bar and stream channel is a poorly sorted mix of sand, gravel, cobbles, and boulders more than 1.5 m in depth. A layer of rounded, stream-worked cobbles and boulders, 10 to 50 cm in diameter, is present at 1 to 3 m depth within the floodplain. The sediment overlying this layer varies in texture from loam to fine sand. A small seep is present along the boundary between the terrace and floodplain, but is not gauged. There is no surface flow from this seep during late summer. Flows increase during the winter rainy season, and peak during storms. Sampling frequency: irregular A network of wells was installed on a gravel bar and a portion of the adjacent floodplain of McRae Creek (see Figure) between 1989 and 1992. Water depths were measured in each well to monitor changes in the elevation of ground water and hyporheic water among seasons and within storms.

Andrews Experimental Forest is a living laboratory that provides unparalleled opportunities for the study of forest and stream ecosystems in the central Cascade Range of Oregon. Since 1980, as a part of the National Science Foundation Long Term Ecological Research (NSF-LTER) program, the Andrews Experimental Forest has become a leader in the analysis of forest and stream ecosystem dynamics. Long-term field experiments and measurement programs have focused on climate dynamics, streamflow, water quality, and vegetation succession. Currently researchers are working to develop concepts and tools needed to predict effects of natural disturbance, land use, and climate change on ecosystem structure, function, and species composition. The Andrews Experimental Forest is administered cooperatively by the USDA Forest Service Pacific Northwest Research Station, Oregon State University and the Willamette National Forest. Funding for the research program comes from the National Science Foundation (NSF), US Forest Service Pacific Northwest Research Station, Oregon State University, and other sources. Data were provided by the HJ Andrews Experimental Forest research program, funded by the National Science Foundation's Long-Term Ecological Research Program (DEB 2025755), US Forest Service Pacific Northwest Research Station, and Oregon State University. National Science Foundation: DEB1440409 The Andrews Forest is situated in the western Cascade Range of Oregon, and covers the entire 15,800-acre (6400-ha) drainage basin of Lookout Creek. Elevation ranges from 1350 to 5340 feet (410 to 1630 m). Broadly representative of the rugged mountainous landscape of the Pacific Northwest, the Andrews Forest contains excellent examples of the region's conifer forests and associated wildlife and stream ecosystems. These forests are among the tallest and most productive in the world, with tree heights of often greater than 250 ft (75 m). Streams are steep, cold and clean, providing habitat for numerous aquatic organisms. 1 HF01001 Stream hyporheic and ground water elevations from the McRae Creek network: HF01001.csv 323607 a2153991eb9010f00ea16b671d2b8063 1 \r\n column , " http://andlter.forestry.oregonstate.edu/ltermeta/ltersearch/dataaccess.aspx?docid=HF01001_v2.csv DBCODE Database code char(10) HF010 FSDB database code ENTITY Entity number numeric(2,0) number 1 natural 1.0000 1.0000 DATE_TIME Date and time of depth measurement datetime YYYY-MM-DD hh:mm:ss 9/5/1989 12:30:00 PM 3/25/1993 1:49:00 PM JULIAN_DATE Julian date (yyyyddd) of depth measurement numeric(7,0) number 1.000000 natural 1989248.0000 1993084.0000 LOCATION Location of well.
