Hydrologist Scott Lindsey says it’s just a question of when the snow runs out.
Though creeks of about the same size on the Kenai have crested and are going down, Willow Creek and Montana Creek are still rising. And while temperatures are expected to cool on Saturday, Lindsey thinks river levels will continue to rise through Sunday.
The gauges at different points in the river drainage system show peak levels at very different times of day, which is one example of the complexity of predicting what the rivers are doing. The gauge on the Talkeetna River about a mile above Talkeetna shows peaks between 5 o’clock and 10 o’clock in the morning, but the gauge where the Susitna River flows below the Parks Highway in Sunshine peaks around 4 or 5 o’clock in the afternoon, and local observations are that the rivers peak near 10 pm.
Emergency Services personnel are watching the Susitna and the Talkeetna River, which reached minor flood stage level Thursday morning.
