Collecting Event Remarks Water temp. = ? C. This is the same place sampled in 1975. Male and females Gasterosteus in reproductive condition, but not many fry. However 20-30 mm fish most common. Sticklebacks were common in the middle of the stream where current was moderate. This area was overgrown with willows and the stream choked with emergent broadleafs and algae in 1975. Now it is open due to flooding. The stream is much broader with greater discharge now. Also caught Gila orcutti.
