It has two lobed, narrowly connected dorsal fins. The action is slower, but brown trout ... Upper Range Pond, as the name suggests, is the uppermost pond within a chain of three ponds.

These effect sizes were used in noncentral hypotheses tests to assess the ecological condition of potentially impaired sites. A 2004 survey of 35 lakes across their range never found Deepwater and Spoonhead Sculpins (Cottus ricei) together within the same lakes, suggesting competition between these two species (Sheldon et al. A small fish, the slimy sculpin is rarely longer than four inches.
