The Fraser River is flooding. This has implications for paddlers. The lower the level of the river, the further upstream the strait's tidal pulse is felt and the farther upstream the river's flow reverses on the flood-tide. With the river as high as it is now, even at Barnston Island the flow will not significantly reverse on the flood-tide --- the absolute level might change a BIT, and the outwards flow might slow down a tad, but the actual direction of the river's flow will not reverse like it does when the river is low. If you are paddling the Fraser around here, don't count on getting a free ride back upstream on the flood-tide like you can during the dry season.

This is a picture of a post made on the emergency services trailer parked at the Barnston Island ferry parking lot at the extreme eastern end of 104th Ave during last year's freshet, showing the Fraser River at 5.8 meters on the Mission Guage.
Here's a higher rez version:

Here's a link to the realtime hydro data site, you have to click on "I accept", then choose BC, then, "Fraser River at Mission Guage", and it will give you realtime data:

Last I checked it was 5.72 meters on the Mission Guage.

Also, the flooding Fraser raises water levels in the Pitt Lake / Wigeon Slough complex --- you can get much further upstream along the Wigeon tributaries, and up the Pitt Lake headwaters at the north end of Pitt Lake.

Lets hope the weather doesn't heat up too fast because if that big snowpack melts all at once it'll over-top the dykes --- if it get's to 8 or 9 meters on the Mission Guage --- look out.

The Fraser River level seems to have topped out at 5.8 ( meters at the Mission Guage) and has slightly dropped. The weather has cooled off, I guess thats why --- the rate that the snowpack is melting has declined.

But we aren't out of the woods yet.

The weather has cooled off so much here on the lower mainland that they re-opened one of the local ski resorts last weekend because of all the fresh snow --- seriously, I'm not making this up. That's how lousy the weather has been in southern BC lately. In fact, we've had the coldest first week in June since 1940.

Whatever happened to the Pacific High that used to set up shop off Van Isle and just sit there week after week, making good weather and north-westerlies?

Now we seem to get the Pacific Low, which just sits there, spinning off an endless series of cold fronts.

The really sad thing about BC getting all this extra precip that we don't need, is that it means that somewhere else on the globe that DOES need it, isn't going to get it. Rainfall is a zero-sum game (one player's gains must necessarily come from another player's losses).

It's been like this for the last couple/three years now --- I sure hope this isn't what our southern BC summers are going to be like from now on ...

June is typically cold and wet around here. A news weatherperson today referred to it as Juneuary.

Really? Yeah, but not THIS cold & wet, surely ...

As long as it warms up for early July --- thats when I leave for Queen Charlotte Strait/Cape Scott. I'm really looking forward to it --- been planning this trip all year.
