The boat launch at Columbia River Park boat launch is closed at this time due to high and fast moving water. Please do not drive or walk past any caution tape and barriers that may be in place. The boat launch will be opened when the conditions improve and become safe. Please stay away from the shore line as fast moving water could take you away. When driving to and from Columbia remember to not drive through standing water "turn around, don't drown".
