Revised - The recent spate of sunny, warm weather and snowpack melt rates are affecting water levels around the territory.

On Tuesday, a high streamflow advisory was issued for the Klondike River at the Klondike Valley.

The water level on the Klondike River above Bonanza Creek has risen nine centimetres in the past 24 hours, with a similar rise on the Klondike River at Rock Creek.

It’s due to ongoing snowmelt runoff and additional rainfall in the last 48 hours.

Water levels are currently approximately 20-30 centimetres from the minor flooding threshold in Rock Creek.

A flood warning was issued Monday for the Pelly River at Ross River.

The river rose 20 centimetres in the 48 hours previous to Monday, and is now above the five-year return period, the Yukon government reported.

The water level is still rising, although the rate of rise has started to slow. Low-lying areas adjacent to the river are currently flooding as water seeps through berms.

Government crews and private contractors are helping with the situation, with hundreds of sandbags being filled.

A handful of homes are affected.

A public closure notice has gone out for the Ross River pedestrian bridge.

“Rising water levels on the Pelly River have forced closure of the bridge due to safety concerns,” the government said.

“Community Services is monitoring the situation and will provide updates when available.”

Meanwhile, the water level on Teslin Lake rose 18 centimetres in the 24 hours previous to Monday and was expected to surpass the two-year return period today. A high-water advisory was issued Monday.

“All upstream and signal stations for the Teslin Lake basin are continuing to rise as high elevation snowmelt runoff continues,” the advisory states.

“Water levels are expected to continue rising at close to the current rate for at least the next week, with an approximate increase of 1.25 metres over that period.

“Teslin Lake typically peaks near the end of June.”

The public is advised to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the high- streamflow period.

Flood-prone property owners are advised to have a plan in place in the event of a flood. See Yukon.ca/floods for more information.

“We will continue to monitor conditions and will provide updates as conditions change,” the government said.

A flood watch is out for the Liard River and tributaries in the Upper Liard area near Watson Lake.

The river rose 31 centimetres in the 24 hours previous to Monday and is now above the five-year return period level, and is rising at an increasing rate.

As well, a high streamflow advisory was issued for the Yukon River at Carmacks.

The waterway is currently above the two-year return period water level and rose close to 16 centimetres Sunday into Monday.

High streamflow or water advisory indicates lake levels or river flows or levels are rising or expected to rise rapidly, but no major flooding is expected. Minor flooding in low-lying areas is possible.

A flood watch means river or lake levels are rising and will approach or may exceed banks. Areas beside affected rivers and lakes may flood.

A flood warning suggests river or lake levels have exceeded or will exceed banks or flood stage very soon. Areas beside affected rivers and lakes will flood.

Matthew; good observation but guess the answer is that time really flies, especially for government spokespersons.
