This data documents fish response to fish passage and instream habitat restoration treatments. Juvenile salmonid snorkel surveys are conducted pre-treatment and post-treatment. Pool dimensions (length and width), maximum residual pool depth, temperature, flow, and water quality data are also recorded. Minnow traps are deployed in the vicinity of restoration treatments when stream conditions or hazards prevent snorkel observations or where additional monitoring methods are deemed necessary to determine juvenile salmonid presence. Winter Salmonid spawner surveys of potential redds, adult spawners, and carcasses are also performed. Survey data includes a 0.038 MB Snorkel Survey database and a 0.043 MB Spawner Survey database.
