About this dataset
The Extrapolating Logarithmic Flow (ELF) Model is an empirical mathematical model for estimating a 30-day stream flow forecast during the summer low flow season at Water Survey of Canada hydrometric gauge locations in British Columbia. This map provides mapped flow forecast output from the ELF model against assessed mean annual discharge and mean annual gauge level at Water Survey of Canada locations. Data includes: Water Survey of Canada Gauge Name and Number; station location (latitude/longitude); analysed station mean annual discharge; analysed station mean annual gauge height; minimum recorded gauge level; current discharge; percentage of current discharge to mean annual discharge; current gauge height; percentage of current gauge height to mean annual gauge level; ELF Model minimum, maximum and average forecasted flow over following 30-day period; ELF Model minimum, maximum and average forecasted flow as percentage of mean annual discharge over following 30-day period; ELF Model minimum, maximum and average forecasted gauge level over following 30-day period; ELF Model minimum, maximum and average forecasted gauge level as percentage of mean annual gauge level over following 30-day period; time of update of data.
