Santa Ana River Watershed

Santa Ana River Watershed

The Santa Ana River Watershed is known as the largest watershed in southern California that ranges from Big Bear to Huntington Beach. This attributing river is not only diverted from its original path by channelization but urban sprawl was the outcome of this new change. Channelizing the river not only gave opportunity to flood control for purposes of constructing new developments but the harnessing and utilizing the energy diverted from the water. The biggest problems that arise from this channelization are flooding and the effects it has on the ecology. Throughout its course are two dams the Seven oaks dam and Prado dam which were put in as a response to the history of flooding that the river caused.
The downside of the dams are that they not only endanger the animals that inhabit the area but also the vegetation. Even though the dams were intended to be used for habitat restoration and flood control they over looked the conditions that sensitive animals such as the Santa Ana sucker and the kangaroo rat which they suffered lawsuits for. In addition flooding although mostly under control is sometimes still a problem when the levees break and the chances of a massive flood rise. Nonetheless, development around the Santa Ana river did not cease and because of the massive development other issues such as air and water pollution are the outcome of its mass amount.
