Document Description
The project proposes to perform preliminary sediment sampling (i.e., exploratory trenching) to characterize subsurface sediment conditions at three locations, along the Greenhorn Creek arm of Rollins Reservoir, between the main body of the reservoir (to the south) and Greenhorn Creek (to the north). This project will be done in support of the larger sediment removal project that would take place on Rollins Reservoir, at a later date. The purpose of the exploratory trenching and sediment sampling is to perform analytical testing for metals, record the sediment stratigraphy, and perform particle size analysis for composite sediment samples. Three trenches will be dug when flows in Greenhorn Creek are low and existing sediment is dry. Access to the site will be via an existing NID access road.
