into the Jerome Park Reservoir. In January 2007, the New York City Department of Environmental Protection reportedly began a $74 million project of improvements to the Croton Falls Reservoir and the Diverting Reservoir. The upgrading and rehabilitation is part of the city's effort to comply with state and federal dam safety regulations. At the Croton Falls Reservoir, the spillway - the structure that allows excess water to leave the reservoir - will be widened and deepened. The nearly earthen and masonry dam will be resurfaced, a new bridge will be built over the redone spillway and various mechanical items, such as valves, will be replaced. In addition, cables anchoring the dam and spillway to the bedrock will be installed. The work will require the reservoir to be deepened . The connecting channel between the two reservoirs will be emptied, inspected and dredged. Construction at both sites is expected to continue until Jan. 31, 2010.
