New orthophotos allow for much greater accuracy. A2. MDC Mystic River Hydrologic and Hydraulic Study The MDC has contracted Camp, Dresser and McKee (CDM) for a study and conceptual de- sign for the new Upper Mystic Lake Dam. This project includes a hydrologic and hydraulic (H&H) study of the Mystic River Watershed (Phase I) and the development of required dam safety improvements recommendations as well as the conceptual design of a fish ladder at the Upper Mystic Lake Dam (Phase II). The objectives of the study are to identify constric- tions that prevent flood flows from reaching the Amelia Earhart Dam and pumping station and to establish the role of the Upper Mystic Lake Dam in flooding within the basin. Ex- tensive hydrologic and hydraulic modeling has been conducted and findings were presented to the public in April 2003. The major conclu- sions presented are: • Flood obstructions have been removed. No other identifiable constrictions on either the Mystic River or Alewife Brook exist. • No localized constrictions exist that are cost-effective to eliminate • Not practical to reconstruct Alewife Brook and Mystic River channels or tun- nel flow to alleviate problem • Upper Mystic Dam safety improvements can be made without adversely affecting downstream flooding levels • Flood monitoring program is recom- mended to collect better data for future projects. Any applicable findings of this study will be incorporated into the design development of the Alewife Reservation and Alewife Brook Greenway restoration. A3.
