UPCOMING GATE CHANGES - JULY 2018

The International Lake Superior Board of Control, under authority granted to it by the International Joint Commission (IJC), advises that the gate setting at the head of the St. Marys Rapids will be adjusted on Monday, 23 July 2018.

A construction project to automate Gates #11-14 is scheduled to begin next week. On Monday, 23 July, Gates #2 through #8 will be raised to a setting of 76 cm open and Gates #9 through #15 will be temporarily closed to allow the construction equipment to be moved into the area. On Wednesday, 25 July, Gates #14 and #15 will be partially opened 76 cm each. Gates #9 through #13 will remain closed while the first phase of construction proceeds. There will be no change to the setting of Gate #1, which supplies a flow of about 15 m3/s to the channel north of the Fishery Remedial Dike. Gate #16 will remain set to 5 cm open to facilitate sea lamprey trapping.

Adjustments to the gate setting are expected to continue in August as the gate automation project proceeds. Anglers and other users of the St. Marys Rapids need to be cautious of the changing flows and water levels that will be experienced in the rapids in July and August.
