UUpper Thames River Watershed no longer experiencing Low Water Conditions (January 14, 2026)

A review of stream flows as well as 30 and 90 day precipitation data indicates that the Upper Thames River watershed has returned to Normal Low Water Conditions, thanks to the recent snow, rain, and snowmelt. The watershed had been in low water conditions since late August 2025. 

The Ontario Low Water Program was developed to support local response in the event of drought. Under this program, each Conservation Authority has formed a Water Response Team to provide information and recommendations to help local interest-holders and watershed communities reduce and better manage water use.

Precipitation and stream flows are the key low water indicators. The program provides the following definitions for the three-tiered system used to inform the public of local low water conditions:

• Low Water Level 1: Early indication of a potential drought condition.
• Low Water Level 2: Increased likelihood of drought conditions.
• Low Water Level 3: High likelihood of drought conditions (does not imply an emergency).

The Province's Low Water Response webpage has a map with current provincial conditions.
