We have initiated long-term monitoring of streamflow in headwater streams on the Prospect Hill Tract at the Harvard Forest. In addition, we have periodically recorded summer flow conditions longitudinally along the length of headwaters within Harvard Forest to obtain information about spatial heterogeneity of flow and of availability of aquatic habitat within these headwaters. In summer of 2003, we recorded streamflow each week at 20-m intervals along the length of two tributaries of Nelson Brook, Tributary A, from Route 32 to its outlet from the Black Gum Swamp, and Tributary B, from its junction with Tributary A to its origin in wetlands north of Prospect Hill Road.

Each stream channel is flagged at 20-m intervals. 0 represents the most downstream point on the study stream; successive numbers represent 20-m distances upstream from the 0 point to the seasonal head of flow.

Weekly monitoring of streamflow in a subset of the streams in summer, 2003, involved recording flow characteristics in each 20-m reach (e.g., continuous flow, flow interspersed with stagnant water, pools interspersed with waterless stretches, dry channel). In fall 2004 stream gages were installed in three tributaries, Nelson Brook A and E (BGA and BGE) and Bigelow Brook west (PHA). In fall 2007 these gages were instrumented for continuous measurement of water level and temperature (see HF070).
