Drought conditions persist throughout most of Mississippi Valley watershed

June 20, 2016 MISSISSIPPI VALLEY WATERSHED—Dry weather continues to dominate the Mississippi Valley watershed. Flows in the main branch of the river are approximately 25% of normal, while flows in the smaller tributaries are close to 10% of normal for this time of year. Most of the upper lakes in the watershed remain at or slightly above their summer target levels but they too have begun to drop over the last week. Although there is some rainfall in the forecast for today, the amounts predicted are expected to have minimal impact on existing conditions. Rainfall and flows both indicate that the Mississippi River has reached Minor Drought severity while many of the tributaries are at or close to Moderate to Severe drought conditions.

Water conservation is recommended for everyone within the watershed although it is less critical in the urban area of Ottawa that is served by a water system that draws water from the Ottawa River. Those who have permits for taking water from surface or groundwater sources are encouraged to reduce their actual taking as much as possible. Residents on well systems are also urged to use water conservatively. Using rain barrels to capture any rain to water lawns and gardens, and avoid using pressure washers to clean houses, driveways, decks and fences all contribute to the conservation of our water resources. Municipalities may have invoked water restrictions, so check your municipality’s website for water restriction bylaws. For more water conservation tips visit <> .

A significant rainfall over a large portion of the watershed will be required to return the watershed to normal conditions.

Daily water levels and flows are available on the MVCA website at <>

In order to track impacts of the drought conditions within the watershed, we request that any individuals or businesses within the Mississippi Valley watershed that are experiencing difficulties with their wells please contact the Conservation Authority by calling 613-253-0006 ext 233 or 243.
