It was an incredible moment, anticipated by <br /> some of us for over a decade.As the old channel dried up,we spent the day moving as many <br /> fish as possible into the new channel. Unscientific counts at a little over 200 small trout <br /> reaffirmed that the channelized section was severely degraded. <br /> Using soils excavated from the new channel work began immediately to refill the old <br /> channel with a natural combination of uplands and wetlands to accommodate flows from <br /> known springs. Due to higher-than-expected ground and surface water flows seeping into <br /> the old channel contractors sculpted a surface flow path when refilling the old channel, <br /> allowing the water to flow downstream into the new channel.We will continue to monitor <br /> these flows,and determine if additional plantings are needed in the old channel to blend <br /> the landscaping into its surroundings.The project budget did not include imported <br /> vegetation for any part of the project. <br /> Immediate overall project objectives were met. The project was on time even after the late <br /> start, and on budget for the tasks budgeted. Goals of using the flow of the river to continue <br /> to sculpt and shape the new channel and not impede its natural functions are being realized, <br /> even with late fall/winter low flows. Improvements to the sewer line and tailings <br /> remediation should improve and protect long-term water quality. Few complaints were <br /> received during construction, and students were enthusiastic during tours and gained a <br /> better understanding of the local ecosystem.Animal tracks indicate that wildlife was <br /> initially curious and checked out the new channel,while a small beaver family created a <br />
