The 3 snow monitoring stations around the valley show the current snow levels are fairly close to where it peaked last year in mid/late April. First graph is from the Graystokes station (Mission creek drainage) east of Kelowna, second is the Brenda mines (Trepanier creek drainage) to the west and the third is Greyback lake (Penticton creek drainage) to the south. The Brenda mines snow levels are still within average range but the Graystokes levels appear highly above average. The Greyback lake station was added in 2015 so there's no average data yet.

Thank u frisk. I was wondering about snow pack levels. I suspect everything will be fine this year. Sure hope so.

Snow Pack at 123%

With snow packs higher than last year, are we worried about flooding and are any steps being taken to minimize possible flooding? Just curious if there is a coming problem.

Part of the issue last year was the mid and high snow packs all came down at once due to a combination of fast high temps and rain that washed it down.

I'm not too worried.

141% is maybe getting closer to snowpack levels of pre-mid 80s levels. imo since mid 80s snowpack levels have been much lower. This is only my opinion

Highest at 4000 feet. For example, Aberdeen Lake is at a record shattering 188% of normal with 250mm of SWE (snow water equivalent) this year! That equates to 89cm of snow on the ground.

Other locations at this same elevation in the Okanagan are also very high. The Summerland Reservoir has 311 mm of SWE, 164% of normal. McCulloch is at 238mm of SWE, or 162% of normal.

Up near Kamloops and in the Cariboo, the snowpack in the 4000 ft range is closer to 200% of normal!

Big Creek in the Chilcotin has 94mm of SWE this year, which is 196% of normal.

Highland Valley between Kamloops and Merritt is at 203% of normal with 156 mm of SWE this year.

Also, it's amazing how much more snow the Okanagan normally gets than the Chilcotin and Thompson areas of the province at the same elevations. Big Creek gets 100mm of SWE, and that's 200% of normal. At the Summerland reservoir, that's way under the normal.

The two driest 4000ft spots in BC are Big Creek and Pavilion (located between Lillooet and Cache Creek). Both average 58 mm of SWE.

Yesterday, I drove by a 950 loader removing snow from the Pennask summit. It looked like a Tonka toy beside the snow pile.
The snow pile up there is 6 feet deeper than my semi is high.

Interesting fact: Mount Timothy in the Cariboo and Big effin' White in the Okanagan are at the same elevation, but Big White normally has way much snow (411mm of SWE versus 266mm). That's because the winter is the wet season in the Okanagan while the summer is the wet season in the Cariboo (generally speaking).

we aren't going to have any lake flooding unless big rains come as well. The lake has been lowered way more than normal.

Mark my words, with at or below average rainfall between now and June the lake will end up being too low.

Streams may flood a bit, that is more a function of how quickly the snow pack melts

but let's all panic

Anyone heard what pro-active plans the municipalities, the Province of BC, the Regional District putting are putting in place, besides adjusting the lake level? Ministry of Forests still hasn't followed up on the recommendations to their 2014 report ("LOWER MISSION CREEK HYDRAULIC CAPACITY STUDY KELOWNA, BC, March 2014) to remove gravel and fix critical parts of the Mission Creek dyke. I'm sure other creeks and rivers are being equally ignored.
