| Topic | Fish: Steelhead Juv. by Age/Reach SF Trinity (E-Fish) 2000-2002 |
| Caption: The chart contains data on the density of juvenile steelhead by age, reach and year. The data are from three field seasons (2000- 2002) of backpack depletion electrofishing on 22 index reaches of two tributaries of the South Fork Trinity River. This was done in order to quantify juvenile steelhead densities during the low flow period of August through September. Juvenile steelhead were encountered in all (100%) reaches in all years. Subyearling densities of juvenile steelhead averaged 0.313, 0.261, and 0.313 fish per square meter for all tributaries, respectively for 2000, 2001, and 2002. Yearling and older (1+) juvenile steelhead densities averaged 0.062 and 0.053, and 0.045 fish per square meter for all tributaries, respectively for 2000, 2001, and 2002. East Weaver Creek was not surveyed in 2001 due to lack of flow. Click on Info Links for more information. | |
