In-stream sand and gravel mining is one of the most prevalent types of mining in Missouri, as far as the number of sites. However, in-stream sand and gravel mining is somewhat of a misnomer because this mining method does not allow for excavating machinery to mine in the flowing portion of the stream.

Aggregates are produced from sand and gravel deposits or from bedrock sources. Production sites are numerous to minimize transport and are more and more in a competing land use position. Urbanization, while creating a market, also sterilizes deposits and pressures producers to relocate further from populated areas.

Fine aggregate including sand – material passing a 3/8-inch screen sieve, essentially all passing a # 4 sieve (i.e., a 0.187-inch square opening). ! Coarse aggregate including gravel – generally considered being crushed stone or gravel, almost all of which is retained on a No. 4 sieve.
