Instream gravel mining is limited to the period from June 1 to November 1, unless an earlier start date is acceptable to the CDFG as specified in the permit. No instream mining operations will be allowed on Saturday, Sunday, or federal holidays, but processing may be allowed on Saturdays outside the ordinary high water mark.
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), wellsorted, and frequently located near markets or on transportation routes.
Instream sand mining regulations are implemented by California State Mining and Geology Board (1977), Califomia Regional Water Quality Control Board (1984), County of Orange (2000) and Flood Control Department of Maricopa County (2001).

Gravel Mining Operations. Gravel mining operations on Wynoochee River being excavated by dragline, Courtesy: Kondolf, 1994. Operations include the wet excavation of riverbeds for gravels and the dry pumped excavation of floodplains. The advantage in the later method is the ease of excavation, whereas the pumping comes at a cost as well.
gravel extraction on river morphology and biodiversity is further discussed in Chapter 2 of this guideline. Sand and Gravel Mining Policy and Guideline The following policies should be taken into consideration before approving sand and gravel mining permits: a) Ensure conservation of the river equilibrium and its natural environment.
Sep 03, 2014· Advanced economies use a lot of aggregate, about 6 to 12 tonnes per person per year. Most aggregate comes from hard rock quarries but some is sourced from river gravels. It is well know that mining gravel from rivers can cause a lot of problems. Moving gravel miners out of the river and onto the floodplain is.
that instream mining is the prevalent type of sand mining in the study area and accounts for about 51% of the sand mining operations along Nzhelele River whilst flood plain mining only constitute 44%. A very small percentage (5%) of the operations employ both instream and floodplain mining in the study area.
