Flash flooding disrupts the gravel along the creek bottom, making it difficult for fish to spawn. Current restoration efforts to Johnson Creek are vital to the stream's health. For many years this natural system has been severely altered by industrial and residential growth. Development of the area has increased flooding dangers and led to a decline in water quality, wildlife and native vegetation. Fish habitat is nearly non-existent. Courtesy of Portland Park Bureau   Much work remains to be done to restore the natural systems that once flourished in and around Johnson Creek. With the help of local agencies like Portland Parks and Recreation, the Bureau of Environmental Services and METRO, the Johnson Creek Watershed Council organizes several cleanup and landscaping activities each year to help restore the natural balance and beauty of Johnson Creek. These activities have extended to the Springwater Corridor, a former rail corridor that was converted to a recreational trail managed by Portland Parks and Recreation. The nearly 17 mile long trail stretches from Southeast McLoughlin Boulevard in the city of Portland to the town of Boring.
