Activity Type: Monitoring
Subject/Discipline: Monitor Natural Resources
Objectives: The objectives of EMAP are to collect baseline data for 12 western states (including Oregon) and determine the current status of aquatic natural resources. The data will be used to assess the “health” of aquatic resources across the western US, as well as within individual states. This is achieved through a random probability sampling design. A total of 15 sites per year in each of the 12 western states, as well as sites in special-interest study areas, will be surveyed in the years 2000-2003.
Findings and Status: Our randomly selected survey location was on a tributary to Union Creek, in the south-west corner of Crater Lake National Park. On Thursday June 28th, 2001, our crew hiked in from USFS 710 (approximately 4.5-5.0 miles) to the Union Creek tributary site location (GPS coordinates = 42.8487, 122.2337). Upon reaching the site, we found the stream to be dry within our prescribed study reach. A scan of the stream both upstream and downstream several hundred meters found the stream to be intermittent, with standing pools and small areas of flow; however, the entire prescribed study reach was dry. No data was collected.
For this study, were one or more specimens collected and removed from the park but not destroyed during analyses? No
