As Fraser Valley residents brace for a weekend of rising waters and potential flooding, Kamloops and Shuswap residents seem to have come through the worst in this latest round of high water.

The River Forecast Centre says flood warnings remain in place for several areas of the southern Interior, including parts of the Shuswap River, Shuswap Lake and South Thompson River.

Highway 97A, three kilometres south of Sicamous, remains closed due to flooding with reopening estimated for Sunday at 5 p.m.

However, all indications point to improving conditions in the coming days.

"There are no significant rainstorms on the horizon and no significant hot spells so conditions are certainly turning more favourable for us," said Chris Duffy, executive director of emergency co-ordination for Emergency Management B.C.

The flood warning for the North Thompson River was reduced to a flood watch Thursday as levels continued to drop.

The Kamloops emergency operations centre was also starting the process of dismantling. But protective Gabion dike systems and fencing along waterways will remain until at least next week.

Planning has begun for picking up distributed sandbags, but that won't happen until next week, according to a City press release.

River closures continue through the Canada Day long weekend due to strong currents, heavy debris in the water and bank erosion.

Shuswap Lake showed a slight decline in water levels near the end of the day Wednesday from its high of 349.41 metres above sea level.

"We've hit peak levels in the lake system particularly in the Thompson Basin so Shuswap Lake, Mara Lake, Mable Lake," said Dave Campbell of the B.C. River Forecast Centre. "For the most part, they're starting to decline now, we're starting to see a bit of easing."

It wasn't enough to allow people in that area to return to their homes, however, after flash floods displaced around 350 people last weekend.

"We do expect those lakes to stay high for a few days," added Campbell.

A do-not-consume water notice also continues for the Mara Water System after a 20,000-litre gas tank fell into the lake on Tuesday.

Premier Christy Clark says she has not yet visited the region because she does not want to be in the way while crews work to clean up the mess, rebuild roads and restore water systems.

Warnings and watches have been downgraded on many other waterways, including several in the Columbia and Kootenay regions, but a flood watch is still posted for the Fraser River from Quesnel through to the Fraser Canyon.

A pulse of water caused by recent rains and heavy runoff is surging down the Fraser, raising concern through the Fraser Valley, where low lying properties could be at risk.
