On Aug 20, 2020, I checked out a few sites on watercourses south of Hammonds Plains Road that feed into Sandy Lake via Johnson’s (Bob’s) Brook, notably in sub-area 12 of the Bedford West Secondary Planning Strategy (see page 11 in that doc showing Bedford West Development sub-areas).
I walked portions of those watercourses, took photos and measured Electrical Conductivity (EC) of surface water, also I checked EC of surface waters at a few points north of Hammonds Plains Road.
There is a large wetland in sub-area 12 and the stream flowing north from it goes through a hemlock lined, steep sided stream corridor; the land east of it is a recovering clearcut. The water EC was high (567 uS/cm) in the stream which was flowing but barely (it had been very droughty). EC was likewise high in the wetland a short distance upstream, and high (700 uS/cm) in water coming out of the northern-most of two culverts on the east side of Larry Utech Blvd (Kearney lake Road). No water was flowing out of the other culvert. This suggests that the high EC/salt content is coming from the tributary draining land west of sub-area 12. It all needs to be followed up when there is higher streamflow.
The area is currently mostly undeveloped, but has been designated for development, re: the Bedford West Master Plan, so it important that the watercourse is protected. The area is also significant as a wildlife corridor.
