This dataset shows length weighted connectivity values summarized by hydrologic unit code (HUC) for a provincial stream connectivity indicator that assesses connectivity for aquatic organisms in stream networks. The stream connectivity indicator supports evaluation and reporting on indicator condition over time and provides information to support management of watercourse crossings. The stream connectivity indicator produces an estimate of the average connectivity in a stream network, considering the movement requirements of local species and the locations of watercourse crossings. The indicator is calculated and summarized using hydrologic unit codes (HUCs). Indicator values are calculated at a HUC 6 scale, and summarized for HUC 8 watersheds at eight timesteps: 2010, 2014, 2016, 2018, 2019, 2020, 2021, and 2022.
