caniapiscau: Caniapiscau River Daily Flows

In FlowScreen: Daily Streamflow Trend and Change Point Screening

Description

This data set includes the mean daily streamflow for the Caniapiscau River. The file has been read from the original .csv format using read.flows. The Caniapiscau River is located in Nunavik, Quebec, Canada, and flows northward. The headwaters (representing 45 percent of the total flow) were dammed to create the Caniapiscau Reservoir, which started filling in 1981. In 1985, the reservoir was diverted to the west into the La Grande hydroelectric complex. This flow time series is used as an example of a river with a known change point to demonstrate the package's screening capabilities.
