2009 BDSS Structures


This pages act as a portal for downloading PDF maps that show the location of beaver dam support structures (BDSS) installed in Fall of 2009 within each of the four treatment reaches (1. Lower Owens, 2. Meyers Camp, 3. Pats Cabin, and 4. Sunflower). Static maps are available at three scales:
  • An Overview - Shows entire treatment reach (e.g. Figure 1A)
  • A Midview -Shows a subreach with multiple BDSS (e.g. Figure 1B; also shows 1 m contours from 2005 Airborne LiDaR survey by Watershed Sciences)
  • BDS View - Focuses just on a single BDSS (e.g. FIgure 1C)
In addition, the majority of the maps fall within coverage of two basemap imagery datasets. The first was a blimp survey flown primarily in November of 2009 (BDSMapsBlimp) and the second was a drone survey flown in April of 2010.

BDSS Maps by Map Navigation

This interactive map shows the distribution of beaver dam support structures (BDSS) that were installed in 2010 as part of the restoration efforts on Bridge Creek. You need to zoom into a reach of interest to see the structures.

BDSS Google Earth Tours

There are brief tours embedded in the above KMZ files. The tours simply take you to every structure in the study reaches. You can  also view them at the following pages:
Note the Google Earth tour feature is a little buggy and does not always display the same in different browsers. The web-based plugins for the tour are somewhat prone to crashing too.
