Oswego Lake Watershed Council

The Oswego Lake Watershed Council (OLWC) is a locally organized, non-profit, non-regulatory watershed stewardship organization established to improve the condition and health of the Oswego Lake watershed and its stream network.

OLWC AND COVID-19

Oswego Lake Watershed Council’s number one priority is the health of our community and volunteers. We appreciate all of you and want you to know that our staff is closely monitoring the spread of COVID-19 and taking appropriate measures to ensure that we are doing our part to promote wellness in the community. Until further notice, all public events, including volunteer events, have been canceled or postponed.

We are continuing to engage with the OLWC community online by using email and our social media platforms. As always, if you have any questions or concerns, please do not hesitate to reach out to us. We appreciate your patience and hope that all of you continue to stay healthy during this challenging time.

Take care,
OLWC Staff and Board

Weed of the Month: Spurge Laurel

Spurge laurel (Daphne laureola) is neither a spurge nor a laurel, but rather an invasive plant in the Daphne family. This perennial plant has poisonous berries, spreads aggressively in our native forests, and is increasingly being found in Clackamas County.

Introduced in Oregon as an evergreen landscape plant, this invasive weed quickly naturalized and escaped into woodlands around the state.
