The dam truth: Climate change means more Lake Orovilles

February 16, Grist:

Just two years ago, Lake Oroville was so dry that submerged archaeological artifacts were starting to resurface. That was in the middle of California’s epic drought — the worst in more than a millennium.

And then the rains came. This winter is on track to become Northern California’s soggiest on record. A key precipitation index is running more than a month ahead of the previous record pace, set in the winter of 1982–1983 (records go back to 1895). Lake Oroville is so full that it spilled over for the first time, spurring evacuations downstream. Read more.

Although spring may be several weeks away, ice cutting machines are preparing for work on the Red River.

Equipment will be on the ice near the mouth of the river early next week and will slowly work its way upstream toward Selkirk.

Amphibex ice breakers will follow suit shortly after.

The province is trying to minimize ice jams before they become a serious problem during spring flooding. Original Article.

Nature sculpts ‘ethereal’ 3-metre-high icescapes on Lake Winnipeg shores

January 24, CBC News:

Crystalline three-metre-tall ice formations are drawing crowds of visitors to the shores of Lake Winnipeg this January.

Winnipeg Beach Mayor Tony Pimentel said in the 30 years he’s lived in the Manitoba community, he has never seen shores so chock full of impressive ice formations in January.

“We’ve had a lot more people come out and look at these things,” Pimentel said.

Following a record-breaking warm November in southern Manitoba, Pimentel said ice on Lake Winnipeg finally began to freeze in December.

The first week of December saw two days of strong northeast winds batter the chilly water up against the sand. As the water lapped up on shore and froze, it turned into slush. It began piling up and solidified as the month continued. Read more.

Southwestern Manitoba faces high risk of spring floods

January 30, CBC:

Southwestern Manitoba is facing a high risk of spring floods, while other parts of the province could also be in store for high waters after the snow melts, the hydrologic forecast centre says.

High soil moisture, snow and winter precipitation levels could mean flooding in most parts of the province, Infrastructure Minister Blaine Pederson said as a spring flood forecast was released Monday.

“We need to be aware of the potential for flooding with the understanding that we have a couple more months of winter weather and the uncertainty of the spring melt rate,” Pederson said. Read more.
