OLWC COVID-19 Plan (Updated May 2021)

Oswego Lake Watershed Council (OLWC) prioritizes the safety of our community, including staff, volunteers, board members, contractors, interns, landowners, partners, and community members. Our COVID-19 field work plan lays out the protocols that will be implemented in response to the ongoing COVID-19 public health crisis in Oregon. This plan will be updated regularly in response to recommendations and requirements from the State of Oregon, Clackamas County, 

Center for Disease Control, and the World Health Organization. All staff, interns, and volunteers working as a representative of OLWC while conducting group work are expected to understand and follow these guidelines.



Educational Opportunities

  • Oswego Lake Watershed Tour   During Summer and Spring OLWC offers monthly watershed tours for area residents to introduce them to Oswego Lake Watershed and provide an overview of watershed science and issues affecting watershed health.  Transportation is in individual vehicles and carpooling for the tours is arranged at the beginning of the tour. Custom tours can also be arranged for groups of up to 15 individuals. Tours are free, but pre-registration is required.

    Description: This field trip begins at one of the headwaters of Springbrook Creek and follows the creek route to Oswego Lake with visits at several key areas along the creek. The tour concludes at Oswego Creek as water leaves the lake and makes its way to the Willamette River. This event is free and family-friendly. RSVP is required.

Garden naturally:

Lake Oswego Backyard Habitat Certification Program

Watershed-friendly household maintenance:

  • Soak up driveway spills with kitty litter and throw in the garbage
  • Sweep your driveway instead of washing it
  • Dispose of household hazardous waste at a disposal facility – drains in the street lead to local streams
  • Install a rain garden to slow down and soak up stormwater runoff on your property

Maintain your vehicles to reduce pollution:

  • Fix vehicle fluid leaks to keep them from washing into streams
  • Wash your car at a car wash or over grass

Even your pets can help:

  • Please pick up after your pets – bacteria from dog waste pollutes our waterways
