Site Description:

The streamflow site is located on a branch of Mewhinney Creek near the northern border of the Delbar property, just below the confluence with another tributary and near an access road. The channel bed is boulder-lined and appears stable, though there is significant vegetation and poison oak in the channel. The original stilling well, installed in September 2017, is attached to a large rock below a cascade in the middle of the channel. The new stilling well, installed in December 2021, is attached to a boulder in a pool upstream of the old site on the north bank. The staff gage was also relocated from the original location near the original stilling well to the same boulder that the new stilling well is attached to. The new gage was installed since the placement of the old gauge in an area that has a waterfall in high flows may have affected the data quality. This site is accessed via a dirt road (the lower road), approximately 2 miles past the Delbar house. The water level sensor is now telemetered as of 31 July 2024, so there is conduit and cable going up the hill next to the streamgage to a datalogger.
