This is the upstream of Pea Brook (SARIS code 33 13975); it needs to be drawn in, matching the USGS maps with imagery, particularly MassGIS Lidar Slope, and have a relation added, with the ref:US:MA:SARIS key. The downstream part (where it flows into the Bear River) also needs to be correctly tagged.

This is Hawkes Brook (SARIS code 33 13900); it needs to be drawn in, matching the USGS maps with imagery, particularly MassGIS Lidar Slope, and have a relation added, with the ref:US:MA:SARIS key.

This is Florida Brook (SARIS code 32 11200); it needs to be drawn in, matching the USGS maps with imagery, particularly MassGIS Lidar Slope.

There are two streams here shown on the USGS maps, that aren't drawn (yet):

Hunterfield Brook (SARIS code 11 00950)
Wheeler Brook (SARIS code 11 00975)

This is Mad River (SARIS code 21 04650); it needs to be drawn in, matching the USGS maps with imagery.

This is Chadwick Brook (SARIS code 33 13675); it needs to be drawn in, matching the USGS maps with imagery, particularly MassGIS Lidar Slope.

This is Miller Brook (SARIS code 33 13525); it needs to be drawn in, matching the USGS maps with imagery, particularly MassGIS Lidar Slope.

This is Harris Brook (SARIS code 33 13450); it needs to be drawn in, matching the USGS maps with imagery, particularly MassGIS Lidar Slope.

This is Stafford Brook (SARIS code 33 13375); it needs to be drawn in, matching the USGS maps with imagery, particularly MassGIS Lidar Slope. Also the downstream part needs be changed from Johnson Brook to Stafford Brook, per the USGS map.
