Our Concerns
Water Quality

MidAmerican
maintains its privilege to use local water resources by successfully meeting
community water quality criteria and standards. Each
MidAmerican subsidiary is responsible for properly managing water discharge
and developing strategies to continuously improve performance.
Where opportunities exist, we work to restore local aquatic habitat and
species. One example is jointly funding the Illinois Quad Cities fish
hatchery that supports the breeding and reintroduction of walleye and
hybrid striped bass in the Mississippi River.
Another example is voluntarily
funding placement of a
mile-long pipe to carry Missouri River water used by MidAmerican
Energy's Neal 4 generating unit to adjacent Browns Lake
and Snyders Bend, rather than returning it to the river. The diversion
restores the lakes' historic water levels by raising the level approximately
three feet and increasing the area under water.
PacifiCorp Energy operates hydropower projects in California, Idaho, Montana,
Oregon and Washington. Pacific Power and Rocky Mountain Power also operate recreation areas
within the hydroelectric system, providing the public with camping, fishing, boating
and picnicking opportunities.
Respect for water resources extends to our hydropower operations, which
use moving water to generate electricity. In the Philippines, CalEnergy's
Casecnan Project also supplies water to
adjacent agricultural lands, providing an important cash crop to the local
community.
Hydroelectric Virtual Tour
Learn how hydropower plants take advantage of a naturally occurring,
continuous process that involves the cycling of water through the environment, known as
the hydrologic cycle, to convert the potential energy from flowing water into electrical
energy by taking a
virtual tour of
the process. |
