Phase 3 Commences

Last week construction began on Phase three of the Benson Creek Stream Restoration project. "This phase involves digging and stabilizing what is referred to is an E channel," says Delta Project Manager Matt Lindsey. An E channel is best described as a highly sinuous stream type with a low width to depth ratio (meaning that it is relatively narrow and deep).

In this case we are digging a channel that is around 3 feet wide and 2 feet deep. E channels are characterized by their natural box-like shape and often overhanging banks. Relying upon thick, deep root systems of riparian vegetation and a highly developed floodplain, the streambed and banks of E channels are highly stable, meaning less sediment entering downstream.

Here, Cache River Project Manager Josh Duzan and volunteer Holly Clinkingbeard (of Fayetteville, AR) install biodegradeable jute fiber matting over a bed of hay and native seeds. This will temporarily stabilize the stream while wetland vegetation takes hold.
