Some reservoir segments not noted in reach_attributes files

Seg_id_nat 2005 traverses Marsh Creek Reservoir (https://waterdata.usgs.gov/nwis/nwismap/?site_no=01480685&agency_cd=USGS) but isn't listed as a reservoir reach in reach_attributes_drb.csv

Note, I suspect this is because Marsh Creek Reservoir isn't in GRaND, but also may be an issue with the algorithm that IDs segments downstream of reservoirs.

seg_id_nat 1565 is the 3rd reach downstream of Cannonsville and correctly listed in reach_attributes_drb.csv as a normal reach (b/c it's beyond the 2nd reach downstream of a reservoir). The temperatures, however, are clearly influenced by the reservoir, at least in some summers.

Yeah, we've been talking about doing distance downstream of reservoir, which we can "easily" derive from the distance matrices. However, it gets complicated when there are multiple reservoirs upstream. Maybe we need "distance to nearest reservoir"?

[janetrbarclay]

Yeah, and maybe something re: reservoir size?

Seg_id_1571 is another one (a few reaches down from 1565)
