Pocket Park

Mosier, Oregon

from "Friends of Columbia":
The trail begins on the east side of Mosier Creek, next to a park bench. Mosier's Pocket Park trail, gently climbs above the rim of Mosier Creek Gorge. Take a minute to walk through the small pioneer cemetery. Next you'll come to a viewing area, peering into the deep canyon and looking upriver to the falls. Continue through the oak groves to the top of the 100-ft waterfall. This makes for a nice picnic spot or if you're feeling more adventurous, jump off the cliff into the sparkling pool below that is surprisingly warm in the summer.

MONITORING FREQUENCY

Pocket Park is not sampled

SOURCE INFORMATION

The Oregon state water quality standard provides that a single sample shall not exceed 406 E.coli colonies/100 mL of water and the geometric mean of 5 samples within 30 days shall not exceed 126 colonies/100 mL. The EPA recommended standard is more protective and provides that a single sample shall not exceed 235 colonies/100mL and the geometric mean of 5 samples within 30 days shall not exceed 126 colonies/100mL.

The Swim Guide will utilize the EPA standard for Oregon beaches.

There is currently very limited water quality monitoring of Oregon's inland swim beaches. The federal Beach Act does not cover freshwater or riverine beaches, and the state of Oregon does not monitor swim beaches or recreation sites on the Columbia. Columbia Riverkeeper monitors recreation sites in the Columbia River Gorge through their Volunteer Water Quality Monitoring Program. Most sites are sampled monthly and high priority sites are sampled weekly from June-September.

The Swim Guide's safety ratings are based solely on E.coli levels. While E.coli concentration is a useful indicator of fecal contamination, there are many other potential sources of pollution that are not reflected in the Swim Guide. These include other bacteria, heavy metals, pharmaceuticals, and pesticides that may harm aquatic life. On the Columbia and other salmon rivers, high temperatures threaten fish that need cold water.
