Environmental Program


Ocean Acidification Project 


The Environmental Department has implemented a water quality monitoring program on traditional and customary streams.

Currently, we are monitoring the Thorne River and Control Lake stream systems. Our goal is to have 2 temperature logger data and (3) locations for our team to collect more baseline data.

We are seeking sites of tradition use areas and if anybody has any insight on locations, please call 907-826-5125.

During the week of May 6th - 10th, our environmental department went to Sitka, AK for HAB review, microscopy work, and for the introduction for nutrient sampling as well as the update on the biomass survey some tribes started last fiscal year. This year, we are excited to begin send samples for the nutrient testing at our HAB net tow sites. Exciting things are in the works for baseline data on Ocean Acidification baseline data. For any information regarding OA, HABs, or anything else regarding SEATOR, please don't hesitiate to call us at 826-5125 or look at SEATOR's website:!

Meet Chaetoceros!

This phytoplankton has a chloroplast and a cell wall making it a diatom. This particular single celled algae has four setae (spine-like lines) on each cornerof an individual cell. Under a microscope will a person see some species in coiled, curved or straight forms. A cell can range from ~2 um to ~35 um and less than or more than 30 cells chained together. Any species of Chaetoceros can be found in freshwater or saltwater samples.

What is IGAP?

IGAP is a federal Act authorizing the Environmental Protection Agency (EPA) to provide General Assistance Program (GAP) grants to federally-recognized Tribes and Tribal consortia for planning, developing, and establishing environmental protection programs in Indian Country, as well as for developing and implementing solid and hazardous waste programs on Tribal lands. The goal of this program is to assist Tribes in developing the capacity to manage their own environmental protection programs, and to develop and implement solid and hazardous waste programs in accordance with individual Tribal needs and applicable federal laws and regulations.

Current Craig Tribal Association IGAP Programs


The Craig Tribal Association, along with (17) Alaska Tribes, formed a partnership to monitor for Harmful Algal Blooms or HAB's. The Southeast Alaska Tribal Toxins (SEATT) group works with NOAA to monitor specific types of phytoplankton that can carry toxins that have a potential to be consumed by shellfish and other resources.  These toxins cause Paralytic shellfish poisoning (PSP), Amnesic shellfish poisoning (ASP), and Diarrhetic shellfish poisoning (DSP) in humans. The data collected will help NOAA and SEATT in establishing a HAB early warning system for researchers, shellfish growers, resource managers, and subsistence users in Southeast Alaska. Here are our recent results for the Craig area.

Side Note from Environmental Planner, Shannon Isaacs:

This is a common phytoplankton I view almost every time from my net tow at our graveyard and False Island boat launch site.

Sorry for the delay in results...

Our next sample date is approx. January 23rd!​

Thank you to everyone that helped with getting batteries off the island! A big thank you to Robert Jackson with KCA for helping use the forklift, and Barry Peratrovich at the City of Klawock with the front loader! We appreciate everyone that was involved with this project.
