1: Epifaunal Substrate/Available Cover:
Score: 20/20 (optimal)
notes: plenty of fallen branches in the water, and the substrate is mostly medium to large rocks that make perfect microhabitats
1: Epifaunal Substrate/Available Cover:
Score: 20/20 (optimal)
notes: plenty of fallen branches in the water, and the substrate is mostly medium to large rocks that make perfect microhabitats
2: Embeddedness :
Score: 16/20 (optimal)
notes: there is some embeddedness, but definitely not more than 25%, even in the more heavily embedded areas, which is surprising given the recent flooding and high turbidity
3: Velocity/Depth Regime:
Score: 20/20 (optimal)
notes: it isn't a large stream, but the frequent large obstructions provide every type of velocity/depth regimes several times over
4: Sediment Deposition
Score: 13/20 (suboptimal)
notes: there were a few enlarged silt bars, but overall surprisingly little given the recent flooding
5: Channel Flow Status
Score: 14/20 (suboptimal)
notes: there was a bit of exposed substrate on each side, but it was less than 25%. (note: there was a sizeable chunk of the stream which changed course for several meters before returning to the usual bed, but I don't count the resulting empty streambed as part of the site, as while it is empty, the new streambed is doing quite well)
6: Channel Alteration:
Score: 20/20 (optimal)
notes: the area is quite remote, and has, as far as I can tell, zero human interference
7: Frequency of Riffles (or Bends)
Score: 20/20 (optimal)
notes: very high frequency but still had plenty of deeper areas. I'd give it a 25/20 if I could
8: Bank Stability
Score (Left): 9/10 (optimal)
Score (Right): 8/10 (suboptimal)
notes: there's a little bit of erosion in places, but very little, and the riparian zone has enough of both small and large plants to form a very solid line that erosion is incredibly unlikely to happen past
9: Vegetative Protection
Score (left): 9/10 (optimal)
Score (right): 10/10 (optimal)
Notes: the site is in a well-forested area, which I believe is why the site survived the flooding so well. the vegetation is dense enough that I almost dropped the e.coli sample on the way back when I tripped over a bush
10: Riparian Vegetative Zone Width:
Score (both banks): 10/10 (optimal)
notes: It would take several minutes of walking to reach the nearest human-affected area
Overall Score: My opinion: 95/100
