The temperature of the water in our streams and rivers is very important to the well-being of fish and other aquatic organisms. Most species need cool water to survive. As a result, Oregon’s water-quality standards include maximum stream temperature criteria. Streams that are monitored and found to exceed these temperatures...
Nutrients and microorganisms in manure can cause water quality problems. When you collect, handle, and land spread manure, this material can get into surface or groundwater supplies. The level of risk depends on many factors.
Swine require supplemental heat
during the first few weeks of life.
Baby pigs demand the most heat
of any young domestic livestock. They
have an immediate need for temperatures
of about 95°F for the first 3 days, then
dropping to 85°F over a 3-week period.

This workbook is an Excel spreadsheet that allows homeowners to compare the cost of using firewood or wood pellets with other fuels for heating their home.
The Oregon Water Quality Decision Aid (OWQDA) is
a first-tier screening tool that allows you to make a broad
determination of the likelihood that a specific chemical,
when applied to a specific Oregon soil, will move through
the soil and contaminate groundwater. This determination
is called the groundwater vulnerability rating.
