Instream sand and gravel mining: Environmental issues and ...

Sand and gravel are widely used throughout the U.S. construction industry, but their extraction can significantly affect the physical, chemical, and biological characteristics of mined streams. Fisheries biologists often find themselves involved in the complex environmental and regulatory issues related to instream sand and gravel mining. This paper provides an overview of information ...

Commercial Gravel Mining. The department permits about 200 in-stream sites, annually. Numerous commercial mining operators across the state excavate sand and gravel deposits, commonly known as gravel bars, as a source of aggregate material. Questions about permitting should be directed to the department’s Land Reclamation Program at 573-751-4041.

Geomorphic and environmental effects of instream gravel mining

Apr 01, 1994  Instream gravel mining involves the mechanical removal of gravel and sand directly from the active channel of rivers and streams. Active channel deposits are desirable as construction aggregate because they are typically durable (weak materials having been eliminated in river transport), well-sorted, and frequently located near markets or on transportation routes.

In-stream gravel mining is a practice that has been found to have extreme impacts, not only to riverine ecosystems, but also to areas the size of entire watersheds and larger. This practice commonly sees the complete removal of the river geometry and associated habitat from bank to bank. The practice has been known to be very

Sep 29, 1998  Gravel mining happens where the gravel deposits are — often in streams and in riparian areas. Gravel mining, particularly in these places, is a concern in many Colorado communities. The Colorado Division of Minerals and Geology (CDMG) is completing a guidance document for use by gravel mine operators who conduct in-stream aggregate extraction.

This Gravel Guidance document addresses three types of instream gravel mining, described as dry-pit and wet-pit mining in the active channel, and bar skimming (or “scalping”) (Kondolf 1993, 1994a, 1997, 1998a). Dry-pit refers to excavation on dry ephemeral stream beds and exposed bars with conventional bulldozers, scrapers, and loaders.

Jan 30, 2008  The effects of instream gravel mining may not be obvious immediately because active sediment transport is required for the effects (e.g. incision, instability) to propagate upstream and downstream. Given that geomorphically-effective sediment transport events are infrequent on many rivers, there may be a lag of several or many years before the ...
