Programs and results

What we aim to solve

SOURCE: Self-reported by organization

Cook Inletkeeper uses a unique blend of advocacy, science and outreach in its mission to protect Alaska’s Cook Inlet watershed and the life it sustains. Inletkeeper’s advocacy work is aimed at reducing fossil fuel production and toxic pollution while helping to build an equitable renewable energy system. Inletkeeper’s decades-long stream temperature monitoring efforts highlight the intersection between climate change and wild salmon, ultimately informing land and water management decisions. Together, this work creates a strong foundation to press for meaningful long-term policy, regulatory, and societal change.

Our programs

What are the organization's current programs, how do they measure success, and who do the programs serve?

Salmon Habitat Program

Cook Inletkeeper’s Salmon Habitat Program supports our goal to protect healthy salmon habitats and clean water. The Watershed Watch Project envisions sustainable human development that protects salmon streams, wetlands and other sensitive wildlife habitat areas from pollution and habitat destruction. Cook Inletkeeper relies on its “eyes and ears” network of concerned citizens to report incidents of pollution and habitat destruction to our toll free hotline (1-888 MY INLET), and organizes citizens to comment on large-scale development proposals and defend environmental policies. The Science-based Land Conservation Project promotes biodiversity in the watershed by protecting critical cold-water habitats using thermal imagery to identify groundwater inflows which create cold water stepping stones salmon will need to move up and down otherwise warming streams.

Population(s) Served

Cook Inletkeeper’s Energy Transition Program supports our goal to accelerate the transition to an equitable, decarbonized energy future. Cook Inletkeeper recognizes climate change as the most pressing threat posed to our natural systems and the people, communities and economies they support. The Energy Transition Program works to move energy projects and policies away from fossil fuel production and consumption, and toward renewable energy alternatives and lasting jobs that minimize impacts to fish habitat, water quality and human health. Cook Inletkeeper’s targeted energy strategies include aggressive legal, scientific and technical advocacy, effective citizen education and organizing, and persuasive media outreach.

Population(s) Served

Cook Inletkeeper’s Capacity Program supports our goal to build a healthy organization with the capacity to achieve its vision. Cook Inletkeeper works to build the internal operations capacity needed to maximize organizational effectiveness and efficiency. Through this program Cook Inletkeeper; a) grows a broader constituency for change in Cook Inlet; b) builds a diverse and sustainable funding base; c) enhances staff and board development through trainings, network meetings, and shared initiatives; and d) engages in strategic planning to maximize organizational productivity and effectiveness. A detailed annual work plan guides Cook Inletkeeper staff and is based on our strategic plan that includes concrete mechanisms for evaluating progress on a quarterly and annual basis.

Population(s) Served

Cook Inletkeeper's Local Resiliency Program is focused on building strong climate-resilient local communities. We work towards this through our local food initiatives which include 1) expanding access to local food and opportunities for farmers via the Alaska Food Hub; and 2) supporting farmers and markets through the Alaska Farmers Market Association. In addition we support community-led climate solutions through our Drawdown Climate Action Series and Actionkit

Charting impact

Four powerful questions that require reflection about what really matters - results.

Our long-term goals are to empower change and civic engagement through advocacy, science and outreach to:
1. protect healthy salmon habitat and clean water;
2. accelerate the transition to an equitable, decarbonized energy future;
3. build strong climate-resilient local communities; and
4. increase our organizational effectiveness at achieving our vision of thriving and equitable communities in a resilient Cook Inlet watershed.

Inletkeeper amplifies and implements its advocacy and science through a combination of community organizing and strategic communications. Inletkeeper engages with local communities and a strong coalition of groups in Alaska working to build a bridge to the future by protecting wild salmon landscapes and addressing the climate crisis. Inletkeeper’s organizing work includes building support for sustainable and equitable economies and local climate solutions; and participating in a team of data-driven community organizers who continue to build and activate a base of supporters who will stand up for their ways of life. In all this work, Inletkeeper creates targeted communications to amplify threats and opportunities to make positive change. Together, these organizing and communications strategies connect Inletkeeper with tens of thousands of Alaskans each year, engaging them in long-term relationships designed to build power to ensure a resilient Cook Inlet watershed for generations to come.

Balance sheet

Fiscal Year: Jan 01 - Dec 31

SOURCE: IRS Form 990 info

The balance sheet gives a snapshot of the financial health of an organization at a particular point in time. An organization's total assets should generally exceed its total liabilities, or it cannot survive long, but the types of assets and liabilities must also be considered. For instance, an organization's current assets (cash, receivables, securities, etc.) should be sufficient to cover its current liabilities (payables, deferred revenue, current year loan, and note payments). Otherwise, the organization may face solvency problems. On the other hand, an organization whose cash and equivalents greatly exceed its current liabilities might not be putting its money to best use.

Executive Director

Sue Mauger

Sue studies Alaska’s wild salmon streams and leads Inletkeeper's efforts to highlight the relevance of climate and land-use change in local decision-making. She coordinates regional water temperature monitoring networks and uses thermal infrared imagery to map and protect cold-water habitats: the stepping stones salmon will need to move up and down otherwise warming stream channels. Sue did her undergraduate work at Duke University and got her masters in Fisheries Science from Oregon State University. Sue was among 80 women worldwide selected to take part in the second team of Homeward Bound, a global leadership initiative for women in science, which culminated in an expedition to Antarctica in 2018.
