Columbia Lake Dam – Before and After

After notching and lowering the lake, the dam was removed and SumCo restored the newly exposed riparian corridor on a NJ Wildlife Management Area, opening up a 10-mile river stretch. This dam removal restored connection to the third largest New Jersey tributary to the Delaware.

Webinar: Workforce Development in the Water Sector – by EPA’s WaterSense

Register here. 
Each day, communities and businesses rely on America’s water infrastructure. From drinking water in homes to irrigation for lawns and gardens, thousands of skilled personnel help provide water for a growing population. As the shifting goals and needs of the water sector evolve with climate change, it is important to employ educated and climate-conscious individuals to meet public water needs while reducing water waste and protecting water resources for future generations. Join EPA’s Green Infrastructure Program, the Qualified Water-Efficient Landscaper (QWEL) program, and the City of Santa Fe, New Mexico, as they share how their workforce development strategies create a knowledgeable workforce to combat the dynamic demands of the water sector.
