Future
The dam has been in service for 70 years but was only built with the expectation that it would function for around 50 years before sedimentation and erosion weakened the dam. The dam has weakened and several safety issues have arisen, which is why the USACE has placed it on its list of the nation's most at-risk dams, where it ranked seventh most at-risk in 2006. In 2007, the dam was classified as "Urgent", which is the second-highest classification level of the dam safety rating system used by the USACE. This classification indicates that the dam is a high federal priority for repairs since failure of the dam during a flood is moderately uncertain. The MWCD estimates that if the Mohawk Dam were to fail during a flood, the water normally held back could cost 307 people their lives and up to $449 million in property damage.
According to the MWCD, the dam's greatest problem is the inherent downstream seepage that occurs with most earthen dams. In the case of the Mohawk Dam, this condition is exacerbated by the fact that it was built on highly permeable land, which could cause instability if too much water were to seep through the lower part of the dam. A rehabilitation and repair plan to stabilize the structure has not yet been established, nor has an official cost-estimate been prepared. Funds were set aside by Congress in 2006 and 2007 to analyze the current state of the dam and gather data for a rehabilitation report. The MWCD serves as the local sponsor of the rehabilitation projects and must pay 3.45 percent of the costs. The remainder will be paid by the federal government. In order to pay for their share, the MWCD will levy an assessment of the properties in its 18-county district, requiring those property owners to pay for the dam improvements throughout the entire watershed. The total local-share cost to be paid by the MWCD for the work on four of the dams, including the Mohawk Dam, is estimated to be between $95 million and $135 million.

Famous quotes containing the word future:
“Where have those flowers and butterflies all gone
That science may have staked the future on?
He seems to say the reason why so much
Should come to nothing must be fairly faced.....”
—Robert Frost (1874–1963)
“It is marvelous indeed to watch on television the rings of Saturn close; and to speculate on what we may yet find at galaxy’s edge. But in the process, we have lost the human element; not to mention the high hope of those quaint days when flight would create “one world.” Instead of one world, we have “star wars,” and a future in which dumb dented human toys will drift mindlessly about the cosmos long after our small planet’s dead.”
—Gore Vidal (b. 1925)
“If nations always moved from one set of furnished rooms to another—and always into a better set—things might be easier, but the trouble is that there is no one to prepare the new rooms. The future is worse than the ocean—there is nothing there. It will be what men and circumstances make it.”
—Alexander Herzen (1812–1870)
