ya, once owl starts running trips they update the level everyday (normally in the mid-aft) of that day. their first trip will be in 2 weekends, but then they aren’t running trips everyday, based on when clients come…
anyhow, their site http://www.owl-mkc.ca (i think) has the historic data from past years, so it can help plan when you wanna go maybe
I have been looking for a reliable online gauge for years. Owl is probably your best bet. WT has a spiffy new website, but the most recent update is April 28, and the Ottawakayak site hasn’t been updated since November.
Keep in mind that the level can change dramatically in a few hours, especially when the level is in the “mid-range” between 4-12. The reading for the Owl page will usually be from the morning trip.
