Proulx, N. 2005. Status and critical habitat of threatened, special concern, and rare fish species in nonwadeable portions of the St. Croix River basin. Final report submitted to the State Wildlife Grants Program. 20 pp. State Wildlife Grants Program final report.
In 2004, a survey of the nonwadeable portions of the St. Croix River Basin was performed to document occurrences and critical habitats for fish species that are rare or categorized as threatened or special concern. The majority of the survey sites were located on the mainstem St. Croix River with six on the Kettle and the Snake Rivers. Surveys were separated into two major categories based on methodology; standardized whole fish community assessments using pulsed DC current from a boat mounted electrofisher and non-standardized methods utilizing various fish capturing equipment.
