Goose Lake Redband Trout Rescues
Table 1: Goose Lake Redband Trout Rescues
||no rescues necessary
Severe drought conditions and loss of habitat led to Goose Lake Redband Trout rescues in 2014 and 2015 (see original report below). The rescues were confined to Cold Creek, Modoc County (a tributary to Lassen Creek) and fish were relocated to Lassen Creek (2014) and upper Cold Creek (2015). No rescues were necessary in 2016 (Table 1).
CDFW plans to continue monitoring Goose Lake Redband streams to document post-drought changes in habitat conditions and fish response.
Genetically Unique Species
Goose Lake (Modoc County) is a large, shallow, alkaline lake on the California-Oregon border (map). Historically, the lake had been observed flooding into the Pit River during high water years and drying out completely during drought years. Goose Lake redband trout, Oncorhynchous mykiss spp., represent a genetically unique species of rainbow trout and are listed as a California Department of Fish and Wildlife (CDFW) Species of Special Concern.
Necessity of Rescue
During the summer of 2014, stream conditions and loss of fish holding habitat in Cold Creek, tributary to Lassen Creek which drains into Goose Lake prompted an emergency fish rescue to protect and conserve the Goose Lake Redband Trout (Figure 1). On July 24th, 30th and 31st 2014, a total of 223 Goose Lake Redband Trout were rescued from Cold Creek and successfully relocated to suitable habitat upstream in Lassen Creek (Figure 2).
