Figure 1. Map of sample sites on the Vermilion and North Fork Rivers . Circles indicate sites on the Vermilion River, triangles represent site on the North Fork River and the red bars indicate the dam removal sites. DWN : Downriver of Dam, IMP: Impounded, ROR: Run of River.
Figure 2. Response of environmental parameters to river location and dam removal. Grey indicate pre-removal values and white indicate post-removal values. Values plotted are means +/- standard error. Refer to Figure 1 for explanation of location abbreviations.
Figure 3. Response of QHEI to river location and dam removal of each habitat on both rivers. Grey markers are average pre-removal values and white markers are average post-removal, +/- standard error. Dashed lines are labeled to correspond score to the health of the river. Refer to Figure 1 for explanation of location abbreviations.
Figure 4. Response of Index of Biotic Integrity (IBI) to river location and dam removal of each habitat on both rivers. Grey markers are average pre-removal values and white markers are average post-removal, +/- standard error. Dashed lines are labeled to correspond score to the health of the river. Refer to Figure 1 for explanation of location abbreviations.
Figure 5. Response of total fish abundances to dam removal in each river location. Grey bars indicate pre-removal values and white bars indicate post-removal values. Values plotted are means +/- standard error. Refer to Figure 1 for explanation of location abbreviations.
Figure 6. Non-metric multidimensional scaling (NMDS) ordination displaying impacts of dam removal on habitat and reproductive guild abundances and habitat metrics. Guilds are displayed as black vectors and QHEI and IBI are displayed as a grey vectors. Refer to Figure 1 for explanation of location abbreviations.
Figure 7. Response of guild diversity to dam removal. Grey bars indicate pre-removal values and white bars indicate post-removal values. Values plotted are means +/- standard error. Refer to Figure 1 for explanation of location abbreviations.
