Whatcom County’s booming dairy and agricultural industry has cost Lummi Nation shellfish harvesters millions of dollars already, and a recent closure of shellfish beds in Portage Bay is adding to the tally.

Manure from dairy cows is discharged either directly or indirectly into the Nooksack River, which flows into Portage Bay. In September, the tribe closed 335 acres of Portage Bay shellfish beds to harvest because of high fecal coliform levels that exceeded National Shellfish Sanitation Program standards. Continued poor water quality led to the closure of two additional areas in December, bringing the total to nearly 500 acres of shellfish beds that are unsafe to harvest. More areas may have to be closed in the coming months if conditions are not improved. (more…)

High levels of fecal coliform prompted the Lummi Nation to close 335 acres of Portage Bay shellfish beds in September.

The fecal coliform – mostly from livestock, human and pet waste originating upstream from the reservation – exceeds federal bacterial standards, meaning the shellfish could be unsafe to eat. The voluntary closure affects Lummi’s treaty-protected ceremonial, subsistence and commercial harvest.

“The reservation tidelands are deeply affected by activities along the Nooksack River, which flows into Portage Bay,” said Lummi harvest manager Ben Starkhouse.

Lummi shellfish harvesters lost an estimated $8 million in revenue from 1996 to 2006, when 180 acres of shellfish beds were closed for the same reason.

During that closure, more than $8 million was provided to the region’s dairy industry to stop the discharge of manure into the Nooksack River. But after the shellfish beds were reopened, federal and state assistance with inspections and monitoring was substantially reduced. (more…)

Tribes monitor Puget Sound for toxins

The Jamestown S’Klallam, Nisqually and Stillaguamish tribes are participating in the SoundToxins monitoring program to provide early warning of harmful algal blooms (HAB) and outbreaks of bacteria that could sicken humans.

“We want to make sure shellfish are safe to consume, not just for tribal members, but for all seafood consumers,” said Sue Shotwell, shellfish farm manager for the Nisqually Tribe.

During the shellfish growing season from March to October, tribal natural resources staff sample seawater weekly at designated sites. Additional sites across Puget Sound are monitored for toxin-producing algae by various citizen beach watchers, shellfish farmers, educational institutions and state government agencies. The monitoring results are posted in an online database.

The SoundToxins program helps narrow down the places where shellfish should be sampled for toxins, which is more expensive and time-consuming than testing the water. (more…)

Stillaguamish Tribe testing how mushrooms improve water quality

The Stillaguamish Tribe is testing ways to use mushroom spawn to improve water quality in agricultural areas.

The process, called mycoremediation, allows contaminated water to filter through the fungus’ fibrous roots, which helps reduce fecal contaminants.

“Mycoremediation could help improve surface water management on farms by getting rid of fecal coliform without having to excavate or give up farming,” said Kate Konoski, the natural resources technician for the tribe who is conducting the study. “It’s low-impact, low-cost remediation.”

The lower Stillaguamish River watershed is dominated by agriculturally zoned land. Pollutants from farms include excess nutrients, fecal matter and pesticide contaminated runoff. Excess nutrient and fecal loads can reduce available oxygen, while metals and emerging contaminants can negatively affect salmon spawning. (more…)
