2013 Avian Update

1. Trends at USACE Dams April – present

2. Trends at specific dams in April - present

3. Deterrent plans for 2014


Data Reporting – calculated means

Provide broader trends

Reduce our ability to detect individual behavior

Time scale may soften resolution

► Daily, Weekly, Seasonally

Osprey are common at Bonn, not well represented by seasonal means. Graphically they are swamped out by other birds.

Funding into FY14 The data portal has been paid for by CRFM

through FY13, but will not be starting in FY14.

If the fish managers want to have bird data continued to be reported in-season need to identify this for O&M consideration.

~$30k for all 8 dams and 5 tablet PC’s for data collection & uploading.
