Sunrise stranding pool 1 year monitoring report

This report details the monitoring of the Sunrise Stranding Pool project, focusing on connecting the pool to the main channel, construction, post-project monitoring, and conclusions. The study included measurements of pond perimeter, width, depth, water temperature, and grain size, with findings indicating project durability and resilience against high flows. Recommendations were made to address vandalism and improve public awareness.

  1. Sunrise stranding pool 1 year monitoring report Sunrise stranding pool 1 year monitoring report SACRAMENTO STATE Tim Horner CSUS Geology Department

  2. Problem: • Fry migrated onto • floodplain during • high spring flows • Flows receded • Pool was disconnected from main channel at flows < 3000 cfs • 1000's of fry were trapped, overheated, eaten

  3. Site location: Sunrise Blvd. Isolation pool: river mile 19.7 From: Sacramento County American River Parkway Map

  4. Project history: • Concept: 2004 • Purpose: Low budget remediation of stranding pool (identified in RCMP) • Construction: 10/1/05 • Sponsored by: • Water Forum, SAFCA, BOR, California Fly Fishers • Unlimited, Fly Fishers of Davis, Granite Bay Fly • Casters, Sacramento County, CSUS Geology Dept. • Philip Williams and Associates • Monitoring: CSUS

  5. Project goals: • Connect stranding • pool to the main • channel • Maintain connection at flows > 2000 cfs • Connecting channel specs: • 4' wide • 1' deep

  6. Bobcat Backhoe Methods: Bucket and shovel

  7. SACRAMENTO STATE Post-project monitoring: • Questions: • effectiveness of volunteers • durability of project • 11/2/05: initial measurements • 12/20/06: 1 year update • Measurements: • Perimeter shape and position • Width • Depth • Water temperature • Grain size

  8. River discharge: 35,000 cfs max. outflow Construction date 11/2/05 monitoring 12/20/06 monitoring 2005 2006 2007 From: http://cdec.water.ca.gov

  9. Depth (cross sections) Measurements: Length and width (tape measure) Grain size (pebble counts)

  10. Installed temperature loggers Measurements: Walked perimeter with GPS Temperature logger in pond

  11. Pond perimeter: 12-20-06 1950 cfs 11-3-05 2050 cfs

  12. Pond depth: November 2005 longitudinal cross section (2050 cfs) December 2006 longitudinal cross section (1950 cfs)

  13. Pond width: November 2005 lateral cross section (2050 cfs) December 2006 lateral cross section (1950 cfs)

  14. Connecting channel: November 2005 connecting channel cross section (2050 cfs) December 2006 connecting channel (1950 cfs)

  21. SACRAMENTO STATE Conclusions: • Volunteers are good, but a Bobcat • is better • New channel withstood 35,000 cfs flow (10 year event) with little change • Vandalism was the biggest problem • Signs or information for the • public might help
