CARNATION, Wash. -- As the reality of darkness swept over Meredith Molli's farm, she showed no sign of stopping what she was doing. Knelt beside a long row of bok choy, the farmer was determined to harvest what she could before an expected early flood wiped out her crop.

"It's a money issue," said Molli, "If this food gets flooded, it can't be consumed. If I can't sell it, then it's harder to pay my mortgage, right?"

The Goose and Gander Farm sits next to the Snoqualmie River, which is well-known for its floods. Low-level flooding is expected through Friday. What is different is the timeframe.

"We sort of say, anytime after November 1st, you should expect a flood," continued Molli, "Maybe we need to start saying anytime after October 1st."

Molli's parner Patrick McGlophlin is on the Snoqualmie Valley Preservation Alliance. The group is about to deploy a tool to help measure and gather information on the area's floods.

"This is designed by someone smarter than me," joked McGlophlin, holding an electronic measurement device, "We all know we live in the flood plain. But, the more we can plan and be prepared and see if there is something causing earlier, higher floods, the better."

The association plans to install ten devices along the river next month, supplementing what the National Weather Service uses. A study is also being conducted to better understand flooding in the Snoqualmie Valley.

"Instead of wining and complaining, we're going to do it," said McGlophlin.
