Figure 1. Daily rainfall, daily water temperature, and hourly water level along the study reach. Upper and lower temperature limits for fish species local to Weslie Creek are labeled on the water temperature graph (LSRCA, 2000; Eakins, 2018). Field assessment days are shown with diamonds along the lower x-axis.

The channel profile has a slope of 0.02 (2%) and the low flow channel had a sinuosity of 1.32 (Figure 2). All cross-sections were identified as asymmetrical, with varying channel bank slopes and different keystone shapes and sizes (Figure 2). Further, rock weir asymmetry alternates between cross-sections (Figure 2). Bed substrate distribution curves were developed for each pool feature to reflect the Wolman (1954) pebble count results for the six sampling days throughout the field season. The results of each bed substrate sampling day were merged and organized by pool feature to identify changes in bed substrate composition through the field season. Given the similarity in the bed substrate distribution curves for June 22, 2018, June 28, 2018, July 13, 2018, July 25, 2018, August 14, 2018, and September 7, 2018, it was determined that bed substrate composition did not change during this field season.
