Imperial Valley

Southern California’s Imperial Valley is home to California’s earliest agricultural drainage success story, one that converted a desert landscape to an agricultural one, but at the same time created far reaching consequences.

Integrated Regional Water Management

Integrated Regional Water Management, commonly known as IRWM, aims to collectively manage all aspects of water resources in a region.

This approach includes all constituencies, including those that traditionally have been outside of the water planning and policy process such as tribal representatives.

IRWM reflects an increasing regional self-reliance to meet water supply needs and the recognition that regional water assets, such as groundwater banking, are necessary to reduce the need for water conveyed over long distances.

Invasive Species

Invasive water hyacinth surrounds docks and boats in the Sacramento-San Joaquin Delta. Invasive species, also known as exotics, are plants, animals, insects and aquatic species introduced into non-native habitats.

Often, invasive species travel to non-native areas by ship, either in ballast water released into harbors or attached to the sides of boats. From there, introduced species can then spread and significantly alter ecosystems and the natural food chain as they go. Another example of non-native species introduction is the dumping of aquarium fish into waterways.

Irrigation

Irrigation is the artificial supply of water to grow crops or plants. Obtained from either surface or groundwater, it optimizes agricultural production when the amount of rain and where it falls is insufficient. Different irrigation systems are not necessarily mutually exclusive, but in practical use are often combined. Much of the agriculture in California and the West relies on irrigation.
