  • "Federation Corner" Column the Montgomery Sentinel - July 6, 2006
    "Federation Corner" column The Montgomery Sentinel - July 6, 2006 Proper maintenance of Lake Needwood long overdue by Wayne Goldstein MCCF President For several days last week, thousands of county residents were evacuated from their homes after county officials became alarmed at water seeping through Lake Needwood's dam. Although this emergency is over for now, this is the right time to look more closely at other problems at Lake Needwood. This July 20th will mark the 50th anniversary of the 1956 flooding that killed six county residents and sparked the drive to help prevent such future killing floods by building flood control dams on Rock Creek. The drive to build the dams, led by an activist citizens group known as the Rock Creek Watershed Association, also included a demand by the group to change zoning and soil conservation laws. These citizens wanted to prevent people from building in flood plains, wanted to limit additional impervious surfaces and resulting stormwater runoff, and wanted to minimize the amount of sediment washing into Upper Rock Creek, the lakes behind the dams, and the lower Rock Creek. Construction of the dams that created Lake Needwood and Lake Bernard Frank began in October 1964 and were completed within 2 years with federal funding through the PL-566 program. Lake Needwood was built to provide both flood control and recreational facilities. It is ironic that the biggest flood threat this time was the fear that the dam holding back Lake Needwood might fail. The 1988 dam inspection report states: "Overall, this is one of the best maintained PL-566 dams in state..." The first specific mention of seepage through the Lake Needwood dam was in 1993.
