42 Cuts to the EPA Proposed by the 45th

With sweeping changes proposed for the EPA by the Trump administration, the potential impact to Oregon and Oregon lakes may still be unclear.  However, the 97% reduction in Great Lakes Restoration Funds that is proposed (300 million to 10 million), may be an indicator of the priorities the current administration has for freshwaters across the US.  Similarly, funding sliced from drinking water and non-point grants to the states has local regulators and environmentalists on alert.  Read more on OregonLive about these and other cuts proposed for the nation’s lead environmental agency.

With the ice and snow of last winter all but in the rear-view mirror of most drivers, the Portland Tribune’s Sustainable Life section offers this look at the environmental impact of the practice of salting roadways.  Salting roads has also been a featured article in Lake Wise (spring 2014), and if last year is any indication, will undoubtedly become a more prevalent topic as Oregonians shift priorities as they shift gears on the highways.  For historical reference, also featured in the Tribune’s article is a glimpse of how the recent “snowmaggedon” actually compared to past events.  Read more….

Smith & Bybee--More Wet than Land this Year

With the wet winter, the status of “lake” returns to both Bybee and Smith.  In drier times the area is often left to the painted turtles to explore.  Also returning this year are the kayaks and canoes.  In fact, thanks to a partnership between Columbia Slough Watershed Council, OLA Members are invited to an upcoming guided paddle event on May 20th.   Space is limited, so RSVP to reserve your spot today.

2017 National Lakes Assessment
Contributed by Shannon Hubler,
Oregon Department of Environmental Quality


In 2017, DEQ’s Statewide Biomonitoring and Toxics Programs will be combining efforts to assess the condition of Oregon’s lakes, reservoirs and ponds.  This joint effort will provide a statewide assessment of the ecological, chemical, and physical conditions of these important waterbodies.  Sampling will occur from June through September of 2017.

The EPA’s National Lakes Assessment, a component of the National Aquatic Resources Survey (NARS), will fund the majority of the sampling effort (29 lakes).  The project is described on the EPA website as follows:

The National Lakes Assessment (NLA) is designed to provide statistically valid national and regional estimates of the condition of lakes.  It uses a probability-based sampling design to represent the condition of all lakes across the coterminous United States.  The survey is a collaborative effort between EPA, states, tribes, federal agencies, and other organizations.

The NLA is designed to answer the following questions about lakes across the United States.

  • What is the current biological, chemical, physical and recreational condition of lakes?
  • What is the extent of degradation among lakes?
  • Is degradation widespread (e.g., national) or localized (e.g., regional)?
  • Is the condition of lakes getting better, worse, or staying the same over time?
  • Which environmental stressors are most associated with degraded biological condition in lakes?
Almost half of the lakes to be surveyed in 2017 are lakes that were monitored as part of the 2007 and 2012 NLA.  These repeated site evaluations will provide information on trends in Oregon’s lakes.

Joint DEQ Efforts

In addition to the 29 lakes funded by the EPA, Oregon is adding 21 more lakes to survey  bringing the total to 50 lakes (Table 1). These additional samples will provide a more robust statistical representation of Oregon’s lakes.  In addition to the national suite of biological, chemical and physical indicators collected as part of the NLA, DEQ sampling crews will collect samples for over 400 different toxic pollutants to further the monitoring goals of the Statewide Toxics Monitoring Program.

Data Reporting

The EPA has published two previous NLA studies, one in 2007 and the other in 2012 .  Key findings from the 2012 NLA study shows approximately one-third of all lakes in the U.S. were in poor biological condition, as measured by the littoral macroinvertebrate community.  Additionally, 35-40% of lakes showed signs of eutrophication, or nutrient enrichment.  Compared to 2007, biological conditions stayed about the same.  However, substantial increases in poor conditions were observed for phosphorus, cyanobacteria, and microcystin.

For Oregon-specific assessments, we did not have sample sizes for NLA 2007 and NLA 2012 that would allow us to do an adequate population assessment of Oregon lakes.  For 2007, we instead assessed the percent of sites surveyed in good, fair, or poor conditions for biological communities and stressors.  Read more here.  Generally, we found fairly similar patterns as shown in the national report, especially for the western mountains and xeric regions.  The 2012 data has yet to be analyzed for an Oregon-specific summary.

The Toxics Monitoring Program produces an annual report that provides the data from each year’s sampling efforts.  Toxics data from 2017 lakes sampling effort should be available some time in 2018 and will be integrated into a statewide lakes report when the complete data set is finalized.

Making Sense of Climate Change
Contributed by Trish Carroll, OLA Board Member

Twenty years ago Lake Wise included an article entitled “Threats to Water Resources from Climate Change,” which discussed possible future impacts of climate on water supplies.1   The article acknowledges that: “uncertainties as to how the region and its hydrology will change in response to a global greenhouse warming are enormous.”  Today climate change appears almost daily in newspapers, scientific journals, and conservation magazines.  The topic of climate change, global warming, carbon dioxide and carbon sequestration, and factors affecting these phenomena, both positively and negatively, is complex and the responses are indeed uncertain.

“Climate change is the most important issue of our time.  The question is can we change our course in time.”  This statement is from Leonardo DiCaprio’s documentary Before the Flood.  Released in 2016, this effort takes a look at Earth’s future if we continue to ignore global warming signs.  Ten years earlier Vice President Al Gore released An Inconvenient Truth, initiating his campaign to educate citizens about global warming.  This documentary has been credited for raising international public awareness of global warming.  A follow-up documentary, An Inconvenient Sequel: Truth to Power, will be in theaters July 28, 2017.  It addresses the progress made in tackling the problem, investment in renewable energies, and the landmark signing of the Paris Agreement of 2016.

The concepts of climate, global warming, and climate change, are inter-related.  Climate, defined as the typical or average weather conditions for a given region, is measured by assessing the patterns of variation in meteorological variables.  Global warming is the term used to describe the current increase in the Earth’s atmospheric and oceanic temperature.  Climate change refers not only to changes in temperature, but also to changes in wind, precipitation, the length of seasons, as well as the strength and frequency of extreme weather events like droughts and floods.  Global warming is a worldwide phenomenon, while climate change can be seen at global, regional or even more local scales.2

There has been an awareness of changes in the Earth’s atmosphere for decades.  The National Research Council’s Climate Research Board sponsored a report in 1979 entitled “Carbon Dioxide and Climate:  A Scientific Assessment” by Jule G. Charney et al.  The report states: “for more than a century we have been aware that changes in the composition of the atmosphere could affect its ability to trap the sun’s energy for our benefit.  We now have incontrovertible evidence that the atmosphere is indeed changing and that we ourselves contribute to that change.  Atmospheric concentrations of carbon dioxide are steadily increasing, and these changes are linked to man’s use of fossil fuels and exploitation of the land.3

The Earth’s climate has always been changing.  There have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age (about 7,000 years ago) marking the beginning of the modern climate era, and of human civilization.  Scientists have pieced together a record of Earth’s climate by analyzing a number of indirect measures of climate such as: ice cores, tree rings, glacier lengths, pollen remains, and ocean sediments; and by studying changes in Earth’s orbit around the sun.  This record shows that the climate system varies naturally over a wide range of time scales.  In general, climate changes prior to the Industrial Revolution in the 1700s can be explained by natural causes, such as changes in solar energy, volcanic eruptions, and natural changes in greenhouse gas concentrations.  Recent trends, however, cannot be explained by natural causes alone, especially since the mid-20th century.  Rather, it is extremely likely that human activities have been the dominant cause of that warming.4   The current warming trend is of particular significance because most of it is likely human-induced and proceeding at a rate that is unprecedented in the past 1300 years.5

The DiCaprio documentary concludes that we have the means of stopping the changes caused by human activities.  Not everyone agrees, nor does everyone agree that human activities are a causal factor in the Earth’s changing atmosphere.  Some do not agree there is even an issue.  Although there is a wide range of views on climate change, there seems to be a growing body of evidence that the planet’s climate is changing, and that humans are a causal factor.

What about effects to lake and wetland ecosystems?  According to a 2015 study jointly funded by NASA and National Science Foundation, more than half of the world’s water supply held in lakes is being warmed by climate change, threatening freshwater supplies and ecosystems.  Using more than 25 years of satellite temperature data and ground measurements of 235 lakes on six continents, this study—the largest of its kind—found lakes are warming an average of 0.61º Fahrenheit (0.34º Celsius) each decade.  Scientists say this is greater than the warming rate of either the ocean or the atmosphere, and it can have profound effects.  Water temperature influences a host of its other properties critical to the health and viability of ecosystems.  When temperatures swing quickly and widely from the norm, life forms in a lake can change dramatically and even disappear.

“These results suggest that large changes in our lakes are not only unavoidable, but are probably already happening,” said lead author Catherine O’Reilly, Associate Professor of Geology at Illinois State University, Normal.  Earlier research by O’Reilly revealed declining productivity in lakes with rising temperatures.  Study co-author Simon Hook, Science Division Manager at NASA’s Jet Propulsion Laboratory in Pasadena, California, said satellite measurements provide a broad view of lake temperatures over the entire globe.  But they only measure surface temperature, while ground measurements can detect temperature changes throughout a lake.  Also, while satellite measurements go back 30 years, some lake measurements go back more than a century.  “Combining the ground and satellite measurements provides the most comprehensive view of how lake temperatures are changing around the world,” Hook stated.

The researchers said various climate factors are associated with the warming trend.  In northern climates, lakes are losing their ice cover earlier in the spring and many areas of the world have less cloud cover, allowing more exposure of their waters to the sun’s warming rays.

Previous work by Hook, using satellite data, indicated many lake temperatures were warming faster than air temperature and that the greatest warming was observed at high latitudes, as seen in other climate-warming studies.  This new research confirmed those observations, with average warming rates of 1.3º Fahrenheit (0.72º Celsius) per decade at high latitudes.

In general, the researchers write, “The pervasive and rapid warming observed here signals the urgent need to incorporate climate impacts into vulnerability assessments and adaptation efforts for lakes.

Regardless of the causal factors for climate change, sharing knowledge of our lake and wetland systems is inherent in OLA’s mission: “To promote the understanding, protection and thoughtful management of lake and watershed ecosystems in Oregon.”  OLA invites you to share your ideas, information and interests on our website, under "discuss and post" to help continue the discussion on climate change and lakes.

Oregon Lake Watch Training Sessions Coming Soon
Contributed by Rich Miller, OLA Board Member

“Hey, what’s this plant growing in my favorite lake, is it an invader, and what’s happening with our water quality?”  You may find answers to these questions by participating in one of our upcoming Oregon Lake Watch (OLW) program training sessions.  OLW is a volunteer-based citizen-science program with two primary goals:
  1. Detecting high-priority invasive aquatic plants and animals early, before they are widespread within a waterbody or spread to other waterbodies.
  2. Collecting simple water quality data that can be used to track the status and trends of our lakes and reservoirs. 
OLW is funded by the Oregon Department of Agriculture and was developed using funds provided by the Oregon State Marine Board and Oregon Department of Environmental Quality.


This coming spring and early summer we’ll be holding several four-hour training sessions where we’ll cover identification of invasive species, field survey techniques, simple water quality measurements, and data management.  This year we’ll also be training and encouraging volunteers to report blue-green algal blooms using the EPA’s bloomWatch smartphone application.  Volunteers who complete the training will be issued sampling equipment and species identification materials.  Volunteer who collect samples twice per year will receive free membership in the Oregon Lakes Association.


Since the OLW program began in 2013, a total of 55 people have completed the training and 35 lakes have been monitored (Figure 1).  Several invasive species have been documented by volunteers including the aquatic plants fanwort (Cabomba caroliniana), Brazilian elodea (Egeria densa), and Eurasian watermilfoil (Myriophyllum spicatum); and animals such as red swamp crayfish (Procambarus clarkii) and Chinese mystery snails (Cipangopaludina chinensis).  Fortunately, the worst-of-the-worst aquatic invaders, Hydrilla (Hydrilla verticillata) and zebra/quagga mussels (Dreissena polymorpha/D. rostriformis bugensis) have not been found in Oregon.


To find out more about the program and our upcoming training sessions, visit our website or send us an email.   Hope to see you later this spring!

Harmful Algae Blooms (HABs) Corner
Contributed by Wayne Carmichael, OLA Board Secretary

 
NATIONAL HAB NEWS:

The recent March 2017 USEPA Freshwater HABs Newsletter demonstrates the continuing discussion, monitoring and research on freshwater harmful cyanobacteria waterblooms and their toxins.  Some excerpts follow:

“NOAA GLERL begins analyzing Lake Erie algal toxins in near real-time.  NOAA’s Great Lakes Environmental Research Laboratory (GLERL) deployed in 2016 the first Environmental Sample Processor (ESP), an autonomous robotic instrument that works as a ‘lab in a can’ in aquatic environments to collect water samples and analyze them for algal toxins in a freshwater system.  This tool can provide drinking water managers with data on algal toxicity in near real-time before the water reaches municipal water intakes.

HAB Tracker Daily Forecast with 3-dimensional predictions of bloom extent.  NOAA’s GLERL developed HAB Tracker, an experimental forecasting tool to aid local managers in decision-making on HABs, that incorporates real-time data with modeling to produce daily updated 5-day forecasts of potential bloom distribution and movement.”

US EPA U-Tube videos on nutrient pollution and HABs.  The US EPA released a series of videos to increase awareness regarding the adverse effects of nutrient pollution and HABs.
Algal Blooms Can Harm Your Health Video 
Algal blooms are not only unsightly; they can make you or your pet sick.  Stay healthy by avoiding contact with water that might have an algal bloom.  When in doubt, stay out and keep your pet out of the waterway.

You Can Prevent Nutrient Pollution Video
Nutrient pollution occurs when too much nitrogen or phosphorus enters a waterway, and is often caused by human activities.  This can harm the waterway and aquatic life, and produce unsightly and sometimes harmful algal blooms.  Do your part to protect our waterways from nutrient pollution.


RECENT HAB DISCUSSIONS SPONSORED BY OLA, CONTRIBUTED BY THEO DREHER, OLA BOARD PRESIDENT


OLA has made a major commitment to discussion and actions to help inform, manage and mitigate the increasing water quality and human health issue of freshwater harmful algae blooms (FHABs).  Highlighting this commitment, two recent Cyanobacterial HAB-related meetings were organized by Prof. Theo Dreher and held at Oregon State University: the Annual CyanoHAB Stakeholder Meeting (1 March, 47 participants), and the CyanoHAB Technical Workshop (22 March, 29 participants).  Both meetings were co-sponsored by OLA and OSU, and held in close collaboration with Oregon Health Authority, the body with jurisdiction over issuing bloom advisories.

The Stakeholder Meeting emphasized the roles of US-EPA, OR-DEQ and OHA in providing information, regulatory guidance and monitoring support for CyanoHABs occurring in lakes and reservoirs.  EPA is currently considering comments to their draft advisory values for recreational exposure to microcystins and cylindrospermopsin.  The recommended value for microcystins is lower than the current Oregon standard, since it is based on potential exposure of children.  It is expected that the final recommendations will be adopted by OHA for the 2018 bloom season.

The Stakeholder Meeting is intended as a forum for sharing experiences of CyanoHABs across Oregon.  Among these experiences, Al Johnson described blooms on US Forest Service lands (including Lake Billy Chinook, which has been monitored only recently despite long-standing blooms), and Brandin Krempasky described monitoring of blooms in Detroit Lake, the source of City of Salem drinking water.  A 7-epi-cylindrospermopsin-producing Anabaena, discovered in Detroit Lake a few years ago, blooms annually for a short period.

The Technical Workshop featured conventional information about CyanoHABs as well as discussion of some lesser-recognized aspects, such as exposure to toxins through irrigation of food crops, exposure to toxins from benthic sources or in rivers transporting bloom material from upstream lakes.  Future monitoring possibilities—using genetic and other technologies and including remote sensing from satellites, aircraft or drones—were also mentioned.

The Workshop included hands-on experience with a dip-stick microcystin assay kit designed to provide qualitative information on microcystin concentrations in recreational waters (kits kindly provided by Abraxis, Inc. and DEQ).  These kits are being used to obtain a rough idea of microcystin levels over time or in different locations, usually providing guidance for taking samples for quantitative analysis.  Participants also had the opportunity to inspect several bloom samples by microscopy.

The programs and slides used to illustrate the talks presented at the meetings are posted at the OLA Events website.

For these events and more, why not join OLA and receive this information in a timely fashion—and as a bonus—be able to participate with discounts.  Join here.
