Watershed focus of events starting Aug. 27
by: Jim Clark Jamie Stamberger, healthy streams program coordinator for the city of Gresham, stands atop a stormwater outfall pipe that leads to a Johnson Creek tributary in southwest Gresham. She says stormwater flows from the  rooftops of area homes to storm drains in the street connected to the pipe. Such a method of stormwater management leads to a much faster rate of erosion than would happen if the stormwater soaked into the ground. Municipalities across the nation are looking to create more eco-friendly forms of storm water management.

Jamie Stamberger, the city of Gresham's healthy streams program coordinator, knows Johnson Creek is not the first thing on most East County homeowners' minds.

However, 'there are plenty of reasons for people to care, even if they're not nature freaks,' she says with a chuckle.

So even if you don't like hugging trees and chasing butterflies, the cleaner the creek and its watershed, the better your property's value, she says.

For instance, she says, a healthy watershed has a slower rate of soil erosion, meaning landslides along the creek - which could literally undermine homes built near it - are less likely to happen.

Amy Lodholz, volunteer and outreach coordinator for the Johnson Creek Watershed Council, a local nonprofit group, adds 'a healthier Johnson Creek means a more beautiful, safer, more valuable and healthier neighborhood overall for East County residents.

'I think it's important for folks in Gresham and any urban environment to realize every part of a city is also part of a watershed,' Lodholz adds.

Water world

A watershed is the area of land where all precipitation drains to a common water body, such as a river or lake. Water runs downstream, so buttes and ranges often form the boundaries of watersheds.

Johnson Creek flows 26 miles from its headwaters near the Sandy River to its confluence with the Willamette River, passing through Gresham, Portland, Milwaukie and Happy Valley and its watershed lies in Clackamas and Multnomah counties.

For the second year in a row, the watershed council and its partners are holding a series of events called Johnson Creek Days throughout the two counties in order to raise awareness of the ecosystem's place in our lives.

'We hope folks in Gresham will join us to explore and celebrate Johnson Creek and to learn about the restoration work that has occurred in this watershed,' Lodholz says.

Here's what lies ahead.

Residential rain gardens

Rain gardens are a great way for homeowners to improve their landscaping, keep polluted runoff out of creeks like Johnson and provide habitat for birds, bees and butterflies, the council says.

On that note, the city of Gresham is offering a free rain garden workshop from 9 a.m. to 1 p.m. Saturday, Aug. 27, at Hollydale Elementary School, 505 S.W. Birdsdale Drive.

A rain garden tour and refreshments will be provided.

For a limited time, residents in parts of Gresham can obtain $200 rain garden grants. For you to be eligible, city staff must confirm the safety of your home's site.

To register for the workshop, call 503-618-2657 or email This email address is being protected from spambots. You need JavaScript enabled to view it..

The city's Healthy Streams Program is also offering free downspout disconnection through Tuesday Aug. 30, as well as free native trees and free natural gardening consultations by appointment.

The Johnson Creek Watershed is comprised of several smaller watersheds or subwatersheds, which include Kelley Creek, Crystal Springs, Sunshine Creek, Butler Creek, Veterans Creek and Badger Creek.


Salmon runs in Johnson Creek helped feed Clackamas Indians, as well as the farmers and others who settled here later.

This is not the case today. These fish, once so vital a part of our region's ecosystem and economy, have dwindled to low levels. However, there's some good news - for example, Coho salmon were seen migrating to the upper reaches of Johnson Creek this year.


Although black-tailed deer and coyotes are the only large mammals that can still be found in the watershed, black bear, bobcat, cougar, wolf, fox and elk were once common. Other mammals also can be found, including beaver, river otter and raccoons.

Birds are the most abundant wildlife in the watershed and include songbirds, ducks, geese, herons, hawks, owls and an occasional eagle.

Salamanders, red-legged frogs and painted turtles also call the watershed home, and sturgeon utilize the mouth of Johnson Creek.

Watershed Action Plan

The Johnson Creek Watershed Council and its partners have developed a Watershed Action Plan to help identify and prioritize restoration and protection programs for Johnson Creek.

The plan can be viewed at Scroll down to the bottom of the home page and click 'Action Plan.'

What you can do

The Johnson Creek Watershed Council offers tips to folks who want to help preserve the watershed.

• Plant native vegetation in your yard to provide shade, shelter and food for fish and animals and to prevent erosion. Native species do not require pesticides or fertilizers and are drought tolerant and disease resistant.

• Put in a rain garden, which manages stormwater runoff because it allows rain to soak into the ground naturally, reducing the amount of pollution that gets into creeks, rivers and wetlands. It also maintains the natural hydrology so streams don't go dry during the summer.

• Eliminate pesticides and minimize fertilizer use. Dangerous pesticides can be deadly to fish and other wildlife. Fertilizers can also harm wildlife by overwhelming streams with unusually high nutrient levels.

Start your own compost pile as a source of natural fertilizer for your yard.

• Disconnect your downspout. Leave gutters in place while directing the downspout into your yard or a rain barrel for yard watering. This can help prevent creek flooding by filtering the rainwater through the soil into groundwater, rather than sending it directly into the creek or into a combined sewer.

A word of caution, however - be sure to check with your local government before disconnecting, as some soil types and topography are not amenable to downspout disconnection.

• Remove unnecessary concrete or other impervious surfaces on your property to allow rainwater to soak into the ground, which will provide cold groundwater to Johnson Creek in the summer.

Concrete may be replaced with materials such as pervious paving, flagstones or gravel.

• Prevent runoff by sweeping patios and sidewalks instead of hosing them. Hosing wastes water and carries contaminants into the creek.

Also, wash your car on the lawn with biodegradable soap or at a car wash that recycles water.

• Clean up animal waste to prevent it from washing into the creek and contaminating the water.

• Keep your car properly maintained so oil and other automotive solutions do not run into the creek. Always recycle your leftover motor oil curbside or at automobile shops. Properly dispose of other hazardous automotive products, solvents, or yard chemicals at a hazardous waste facility or neighborhood collection events.
