Wind plays a major role in bird migration. In the fall, wind circulation patterns around highs and lows impact the movement of migratory birds. The ideal time for flying often occurs the day after a cold front passes – north winds, dropping temperatures, rising air pressure and clearing skies are good migration conditions. Soaring birds [...]

World Water Monitoring Day (WWMD) – an international education and outreach program to involve the public in monitoring and protecting water resources – takes place on September 18 each year.

As part of the National Lakes Assessment, the U.S. EPA selected and sampled 155 lakes in the Western Mountains Region (covering the Cascade, Sierra Nevada and Pacific Coast ranges, the Gila Mountains, and the Bitterroot and Rocky Mountains) to characterize the condition of more than 4,100 lakes throughout the area. What did researchers find? More [...]

Earth Gauge Video is available for this tip. Do you like a beautiful yard, but not the time, effort and money required to maintain it? In hot, dry climates, the water required to maintain a lush landscape can be costly. Just one lawn sprinkler operating three times per week can use more than 1,000 gallons [...]

Did you know that almost 60 percent of Americans live an area with unhealthy levels of air pollution? Just like a recipe, the atmosphere needs all the right ingredients to make ground-level ozone – a harmful air pollutant that is common during the summer months.  When the temperature rises and the sun is shining, heat [...]

Have you ever wanted to help keep your community by reporting severe weather?  SKYWARN is a volunteer network of nearly 290,000 trained severe weather spotters around the country.  SKYWARN spotters help keep their local communities safe by providing timely and accurate information to the National Weather Service about weather events like thunderstorms, winter weather and [...]

Residential driveways can account for up to 15 percent of the total paved area in a city or state. These paved surfaces are “hot spots” for accumulation of pollutants like motor oil, antifreeze and yard care chemicals. During a storm, rain water picks up pollutants from paved areas and heads to the storm drain, which [...]

Elusive and beautiful, California golden trout, sometimes known as “fish from heaven,” are found in rivers and streams in the Sierra Nevada high country.
