• Feasibiliy assessment (2003-2004)
• Fish passage way 50% design (2005-2009)
• Fish passage Final Design for 182nd St dam (Dec 2011)
Project History
• Fish Stocking- 200 Alewife (2006)- 400 Alewife (2007)- DEC regulations prohibit
beginning 2007; loophole in regulations may allow stocking after fish ladder is installed.
