Data sheets were filled out for each site which listed all samples that were collected, descriptions of sites, notes, drift times, water velocities, temperatures, dissolved oxygen (DO), and included a map of each site. Additional notes on water appearance, fauna, and general conditions were recorded. Water Quality The water samples consisted of two replicates collected in 116 ml sterilized jars. The jars were externally labeled and kept in a dark cooler with ice until transferred to a freezer for storage. The water was collected by dipping the jar into the water at each site. These samples were analyzed for total organic carbon, total dissolved nitrogen, ammonium-N, nitrate-N, Orthophosphate-P, and total phosphorus. Benthic Invertebrates Benthos samples were collected with a 58 mm diameter core sampler. Replicates of each sample consisted of ten cores for the first week and five cores each for each trip thereafter. Each core in a sample was collected in a five gallon bucket and transferred to a 1,856 ml plastic jar. The samples were preserved in alcohol with an internal and external label. Drift Samples Replicate drift samples were collected at sites with any current. These sites included all main channel sites, inflows, and outflows of floodplain terraces and depressions. The water velocity and time duration of each sample effort were recorded to later calculate the volume of water sampled. The drift nets have a 100 mm PVC pipe mouth with one meter of 80 micron netting leading to a removable cup. The net was removed from the water and rinsed to get everything into the cup. The cup was then rinsed into a 116 ml jar with internal and external labels and preserved in alcohol. Zooplankton Replicate zooplankton samples were collected at each habitat within each site. Samples consisted of four sub-samples collected with a tube four liters in volume taken at mid-depth. The four sub-samples were combined by filtering each through a 80 micron zooplankton net with a removable cup on the bottom. The filtrate was washed from the cup into a 116 ml jar with internal and external labels and preserved in alcohol. Carbon To determine the role of floodplain habitats in carbon transport and storage, drift sampl a at inflow and outflow areas were collected during weekly sampling trips. Drift nets were 1n 11 long, 330 ,um nets and were placed within active channel areas. Flow rates were calculated usi dye transport methodology. Nets were left in the channel from 5 to 60 min, dependi h th 47 m 1 1 1 1 1 1 1 1 J
