River Flows

Last update to river flow plots: April 30, 2018

River flows naturally fluctuate seasonally, with the highest flows normally seen during and immediately after the rainy season (June–September), and the lowest flows at the end of the dry season (October–May). To gage the health of the river, it’s important to compare the flows to the historic averages for that time of year.

The plots below show flows for four rivers over one-year and 10-year time periods. Readings are placed in four categories: above normal, normal, below normal and extremely low. Plots show how actual river fluctuations over those time periods compare to normal flows based on historic averages.

Please note that the 10-year plots include the drought of record in 2000, which is reflected by the extreme low flows during 2000–2001.
