Research findings on inland fish and impacts from climate change are now available in an updatable, searchable database, thanks to a team effort by the National CASC, USGS, and University partners. FiCli (the Fish and Climate Change Database) contains a breadth of peer-reviewed literature spanning geographic regions on a global scale. The data, which will continue to grow as more data are added, will help inform resource managers and spur future studies on fish health and climate.

Southwestern Alaska’s Salmon Face a Grim Climate Future
Using past weather data and future weather pattern predictions in Southwestern Alaska, the National Park Service foresees both a significant decrease in precipitation in the form of snow and a shorter snow season. Over the next fifty years, according to the study, low-lying regions in the Aniakchak National Monument and Preserve, and in the Lake Clark, Katmai, and Kenai Fjords National Parks are likely to transition from snow-dominant to rain-dominant. This shift will reduce overall snowpack and decrease instream flow during summer months unless glacial melt or rain boost runoff. The timing of runoff may negatively impact salmon runs in the summer months, while an increase in streamflow in the winter months, as snow transitions to rain, will threaten salmon eggs with scouring. Warmer air temperatures in the summer months are expected to raise temperatures in non-glacial streams, impeding salmon survival throughout all life stages. It is unlikely that salmon will adjust quickly enough to accommodate to these changes.

Clean Water Act Dries Up Under Trump Administration Rule
A coalition of Democratic attorneys general attempted, without success, to delay the implementation of a new definition of streams and wetlands put forth by the Trump administration. The new “Waters of the U.S.” Rule or WOTUS removes environmental protections for streams, wetlands and groundwater, and is seen as a major win for farmers and land developers. Under the new ruling, pesticides and fertilizers can now be dumped directly into waterways, and wetlands can be destroyed or filled in to accommodate construction projects. Contamination of drinking water from unregulated pollutants puts millions of Americans at risk. The ruling went into effect on June 29th. Read more here.
In another effort to stop implementation of the Rule, the Navajo Nation and several environmental groups filed suite in U.S. District Court in New Mexico against the Trump Administration. The law suit which also includes Amigos Bravos, the New Mexico Acequia Association, the Gila Resources Information Project and the Environmental Integrity Project and other environmental groups also claims that the Administration failed to consider the impacts of Climate Change on western watersheds that are already affected by over a decade of drought. As a result, smaller systems which are affected more by low flows and higher temperatures from drought conditions will be impacted more significantly by reduced protection from polluters. Agricultural and other livelihoods will that rely on Acequia and other non-industrial irrigation systems dependent upon adequate and timely snow, rain and runoff for crops will be put at risk.
According to Navajo Nation President Jonathan Nez, “At this point in time, with climate change occurring around the world, it’s more prudent than ever to protect our land, water and air. We, as Diné People, have a duty to preserve and conserve our natural resources to ensure that our future generations have access to clean water, air and land.”
Melting Permafrost Linked to Russian Oil Spill
In late May of this year, a huge oil tank collapsed in Norilsk, an industrial city in north-central Siberia. An estimated 21,000 tons of diesel fuel spilled into the Ambarnaya and Daldykan rivers coating the water with an oily crimson layer. A failed attempt to contain the spill lead to further contamination downstream as the oil spread northward, entering the 45-mile-long Lake Pyasino, a on its way to the Arctic ocean. One of the largest spills documented in the Arctic, the Norilsk spill has been compared to Alaska’s 1989 ExxonValdez oil spill. As with the ExxonValdez, the spill occurred during spring migration, poisoning the waters just as fish and birds are returning to their natal grounds.
Russian mining firms identified melting permafrost as the culprit – destabilizing the soil under the tank. Clearly, as the arctic warms, the potential for lethal spills increases. Better surveillance of melting permafrost with inexpensive temperature probes would likely have prevented the spill. Despite the up-front costs, preventative measures save hundreds of millions of dollars in clean-up efforts and safeguard wetlands and the wildlife and human inhabitants they support.
Voluntary compensation for damages from Norilsk Nickle in the amount of $148 billion rubles, or $2 billion dollars.
USDA Forest Service Updated “Forests to Faucets” Data released
Forests to Faucets premiered in 2011 to portray the relationship between forests and source water across the U.S. The updated version 2.0 (F2F2) dataset released in April assesses all 88,000 HUC12 watersheds in the U.S. to identify those forests important to downstream surface drinking water supplies and evaluate each watershed’s natural ability to produce clean water. F2F2 includes future risks to watersheds such as development, wildfire or climate-induced changes to water quantity. More information available, here.
Refugia for Climate-Challenged Wildlife
Refugia, or natural areas that are relatively buffered from a changing climate, can offer protection for wildlife and the ecosystems on which they depend. Most species do not have the ability to adapt rapidly to climate change-induced environmental disruptions such as drought and heatwaves. A recent focus on the importance of refugia, including factors such as size and connectivity between adjacent refugia has given rise to a new publication by the United States Geological Survey. Using existing examples and a broader understanding of the complexities of these vital landscapes offers “an opportunity for hope, a chance to be proactive in a time of adversity and uncertainty,” according to Toni Lyn Morelli, USGS Research Ecologist.

Share Your Drought-Related Projects and Activities on the New Drought.gov
In order to provide opportunities for increasing knowledge through networking and information sharing to better predict drought events, the National Integrated Drought Information System (NIDIS) established the Pacific North West Drought Early Warning System (PNW DEWS). To this end, the NIDIS is requesting in-put on drought-related projects and activities that are going on throughout the Pacific North West and in Southern Alaska regions. This information will be displayed on the Drought.gov website (to be re-launched in late Spring 2020).
For more information about the types of activities NIDIS wants to feature on the website and to submit activities, click here. (The form takes about 10 minutes to complete).
In light of experience the first drought experienced in the Southern region of Alaska and likely to continue in years to come, WPC’s asked about whether the NIDIS is planning to establish an Alaska DEWS. In response Britt Parker – the Coordinator of the Pacific Northwest DEWS stated “[w]e are working with partners to identify ways to provide more support for Alaska! While I do not think it will result in setting up a DEWS immediately, we are looking at options for the long term while identifying research and efforts to better understand drought in Alaska in the short term.

Federal Subsistence Management Program Continues Temperature Monitoring Project for Subsistence Rivers
The U.S. Fish and Wildlife Service’s Federal Subsistence Management Program will continue conducting a water temperature monitoring project for the next two summers at rivers and streams throughout Alaska. This effort is associated with fisheries monitoring projects funded through the Fisheries Resource Monitoring Program (Program), and has been ongoing since 2008. According to the Program, temperature can impact fish through changes in metabolic rate, primary production, respiration, growth, decomposition, water chemistry, migration timing and susceptibility to disease. At the same time “[d]evelopment adjacent to stream habitats…as well as changes in climate can potentially cause fluctuations in water temperature beyond the behavioral and physiological tolerance of aquatic organisms, including fish, that could have a deleterious effect on their productivity and availability to subsistence users.”
Federal, State, and Tribal organizations in Alaska are currently collecting water temperature data for such subsistence streams. The Program is looking to highlight the importance of uniform data collection, standardization, and reporting, to ensure that such data is reliable for monitoring climate change and supporting conservation actions.
The Alaska Online Aquatic Temperature Site (AKOATS) platform, hosted by the University of Alaska Anchorage’s Alaska Center for Conservation Science, is currently used to make this data available to the public. The platform was developed with the idea that it would serve as a centralized location to access stream temperature monitoring data collection across Alaska.
Emergency Recovery Plan for Global Freshwater Biodiversity Loss
Covering approximately 1% of the Earth’s surface, the world’s freshwater rivers, lakes and wetlands are home to 10% of all species and more fish species than in all the oceans combined. Posing a threat to global communities who rely on rivers, lakes, and tributaries for food, water, and economic well-being, however, 83% of freshwater species and 30% of freshwater ecosystems have been lost since 1970. In response to the alarming rate of loss of freshwater ecosystems, a recently released study developed by scientists from across a spectrum of environmental and academic institutions outlines a framework for protecting such ecosystems.
Calling it an “Emergency Recovery Plan”, the study proposes six scientifically based strategies to preserve freshwater biodiversity, that have proved successful in certain locations. These solutions include: Returning rivers and streams back to their natural flows; Protecting freshwater from toxic effluents, overfishing, invasive species and mining activity; Protecting critical habitat; and Restoring river connectivity through regulation of land uses and water infrastructure. James Dalton, Director of the International Union for Conservation of Nature Global Water Program says, “all the solutions in the Emergency Recovery Plan have been tried and tested somewhere in the world: they are realistic, pragmatic and they work. We are calling on governments, investors, companies and communities to prioritize freshwater biodiversity – often neglected by the conservation and water management worlds. Now is the time to implement these solutions, before it is too late.”

Radical transformation of the Pacific Arctic Includes Impacts to Freshwater
Scientists from multiple agencies, working collaboratively to supply data to the Arctic Integrated Ecosystem Research Program, are detecting rapid changes in the Bering and Chukchi Seas. These changes are driven by abnormally high water temperatures and rapid loss of sea ice (on par with climate predictions for 2040), and include high numbers of Pacific cod and pollock expanding into Arctic waters, higher concentrations of harmful algal blooms, and a sea bird die-off that began in 2014 impacting puffins, common murre and, most recently, short-tailed shearwaters. At the base of the food web, larger, high-fat copepods are declining while smaller, copepods with a lower-fat content are flourishing. This means less nutrition for Arctic cod, while, at the same time, more competition for these resources as pollock expand their range northward.
But these troubling changes are not limited to northern ocean waters. Inland, freshwater rivers in the Arctic are overheating. Record-warm temperatures in July, 2019 caused heat stress and a mass die-off in returning, pre-spawned salmon. Read more.
