Flood Facts & Fiction
A lot of people think floods only happen in the Midwest, or east of the Mississippi River. Are we really safe from floods here? No. A flood happens when there is more water flowing down a river channel than the river can hold. Some of the water, called runoff, is forced to flow out over the riverbanks into the adjacent land, called the floodplain. The amount of runoff varies from year to year due to variations in snow and rainfall we receive. Some winters are snowier than others! Spring temperatures and rain can speed up or slow down the melting too. A quick melt can produce flooding.
But not all floods are the same. You may have heard of the 100 year flood? It is not one that happens once a century! A 100-year flood can happen any year, and could happen several years in a row. Each year, scientists record the amount of precipitation and runoff. Using statistics, the weather records help establish a probability or likelihood to have a certain runoff. A 1-year flood has a 100% chance of happening every year. This runoff amount will not be large. A 10-year flood is the volume that has a 10% chance of happening every year, and will bring a larger runoff volume. A 100-year flood has a 1% chance of happening. Good thing, because it is much bigger! A 500 year flood has a 0.2% chance of happening this year or any year. Those types of floods don’t happen often, but when they do, look out!
Since they don’t happen very often, people can forget about floods. They may build their house or business in the floodplain. It can get flooded! What should you do if there is a flood at your home? Don’t be scared, be prepared! Before the flood happens, you and your family should have a plan. Check out the resources below to help you make a good plan. Don’t walk or drive in a flooded area.
Floods can happen any time of the year, but are more common in spring. In October 2006, a strong thunderstorm got stuck over Glacier National Park. Lots of rain fell in one spot over a short period of time. The heavy rain caused a flash flood in McDonald Creek, washing out the Going-to-the-Sun Highway, bridges and overlooks. It damaged Many Glacier on the east side too.

BY LUCY SMITH Art has something wonderful and germane to teach each of us; one of the first lessons being that Art doesn’t start out on a wall or a pedestal. Art is created when someone is inspired (or hired) to record something noteworthy. It is a lens, focused on life as experienced across time
Barber Creek Pit more commonly called Barber Pit, a ten acre piece of United States Forest Service (USFS) land in Section 32, has served the Swan Valley in many capacities over the years. Besides the obvious use as wildlife habitat, it has been a Montana Department of Transportation gravel pit, a dumping area for deer
Nancy Zapotocki, Flathead Audubon Education Coordinator The cold of winter is melting away, with the warming arrival of spring. As day length changes and temperatures slowly increase – a wake-up (and welcome back) call goes out to many inhabitants in northwest Montana. One of the earliest plants of the season has already made its appearance

By: Ansley Ford Fall is a delicious time of year in the Flathead Valley! Farms and gardens are overflowing with the summer’s bounty. Melons, apples, potatoes, squash, and many other colorful, nutritious fruits and veggies are ripe for the picking. Whether you’re harvesting from your own backyard garden or taking advantage of the bounty of
By Patti Mason After the spring equinox on March 20th, the days get longer and allow the earth in the northern hemisphere to absorb heat. The sun shines down on the peaks that rim our valley, defining the boundaries of the Flathead basin watershed. The snow which has accumulated in the watershed during the winter
By Diann Ericson “Pollinator” is a collective word referring to dozens of species that spread pollen. Many pollinators are common species, including bees, butterflies, moths, wasps, flies, ants, beetles, bats and hummingbirds. We see them, hear them and benefit from their work every day of our lives. Like them or not, they help put food
By Lindsay Steinbauer Winter is here and you know what that means – howling wind and frigid snow! Each year, as the days get shorter, the temperatures drop, making survival more difficult for our local native plant species. This means that only those plants that are specially adapted to such harsh climate extremes will live
If you missed the March 16 Meeting, no worries, the notes from the meeting are on-line here: FFEC March Meeting Notes There was a lot of positive energy and feedback from the group to bring FFEC to the Flathead Watershed. Those teachers in attendance felt strongly this would be a valued training and even though
In the Flathead Valley we are lucky to be able to experience “winter water in the form of snow. Evaporation from the ocean, lakes, streams, plants, and even our breath puts water vapor into the air. When the air is cold enough snow flakes grow from that water vapor, literally out of “thin air. Snow
By: Lex Blood With the return of winter and snow to the mountains and floor of the Flathead Valley, we are reminded of a time beginning about 2 million years ago and concluding about 10,000 years ago when great masses of ice up to 3,000 feet thick periodically covered almost everything we see today. Initiated
Glacier National Park is famous for its mountainous landscape and glacially carved terrain. What many people don’t realize is that mountain glaciers provide more than just scenery. Glaciers are an integral part of the ecosystem, providing water to mountain and downstream environments. In today’s warming climate, these giant marvels of snow and ice are rapidly
