Dredge Work Restoring Wethersfield Reservoir
by Louise Axelson, Courant Staff Writer
Wethersfield - From a distance从远处看, the 1860 Reservoir, hidden away from Highland Street by shade trees, appears ready to receive summer visitors. What looks like a red, white, and blue pleasure boat floats invitingly on the water.
The town's chief of engineering, James Sheehy, laughingly dubbed被称为 the long, flat piece of equipment "The African Queen," after the craft upon which Katherine Hepburn and Humphrey Bogart fell in love as they chugged 吆喝着though the jungle in the movie with the same name.
The machinery that has been stuck in the mud of the 1860 Reservoir since Wednesday is not as romantic a contraption 奇妙的装置发明as Bogart's boat博加特的船, however. "You're talking about moving 150,000 cubic yards of muck," Sheehy said.
The equipment is a coveted 令人垂涎的piece of state-owned machinery called a Mud Cat™ dredge that will be used to clean out the reservoir, which has become laden负载的 with more mud than water over. Unless the reservoir, which lies in the midst of one of the town's most exclusive最豪华的 neighborhoods, is cleaned out, it will continue to lose its shoreline to weed growth and turn into a swamp, officials have said.
The town bought the 64-acre site of the 35-acre reservoir about 20 years ago with the help of federal open space grants联邦休憩用地资助. Ten years ago, the town started talking about dredging it, Sheehy said.
Complications 并发症ranged from a Town Council debate议会辩论 on whether to spend $100,000 to buy a dredge and to concerns by federal environmental officials about where the dredged material could be dumped.
挖掘过程:The dredging, using one of the state's two dredges, is finally scheduled to begin Wednesday.
The big break 大突破for the project came after the state abandoned its plans to build I-291. State-owned land formerly designated指定的,指派,委任 for the highway corridor走廊通道 in Wethersfield and Rocky Hill turned out to be the prefect repository for the dredged material.
Also, over the past few years, the 1860 Reservoir moved tothe  first place from 11th on the state Department of Environmental Protection's list of ponds needing the dredge, Sheehy said. Two long pipes, one black and one gray, connect the reservoir to two massive craters陨石坑 that straddle 岔开腿,跨坐,横跨-两边the Wethersfield/Rocky Hill line.
After the dredge agitates搅动 the reservoir so the mud and water mix together, the 90 percent water and 10 percent mud combination will gush喷涌,滔滔不绝的说话,涌出 through the black pipe and under Two Rod Highway into one of the craters.
