ALSTEAD, N.H. (AP) – Where Sally and Tim Canfield’s home once stood, there is only open land. Their home was washed away by floodwaters, and two days after the rains subsided, their family found no trace of them.

Search and rescue crews with police dogs looked for the Canfields and Spencer Petty, also missing since the flood hit Sunday, along the Cold River. Boats searched the Connecticut River, which forms the border between New Hampshire and Vermont, downstream from where the Cold River empties into it. Crews also were picking apart debris piles along the river to search for bodies.

A brother-in-law of Tim Canfield, Rick Mason, took searchers and their dogs along the river banks on his ATV Monday, but “we didn’t find any bodies,” he said Tuesday.

“First there was Katrina, then there was the earthquake, but this is pretty devastating right here,” Mason said.

At the site of the Canfields’ home, someone had put up an American flag.

Three deaths were confirmed in New Hampshire from flooding: Steven Day and Ashley Gates, a young couple who died when their SUV plunged off a washed-out bridge into a river in Unity, and William Seale of Alstead, who was found Sunday in a cornfield in Langdon.

A kayaker in Antrim also was missing.

Electricity was mostly restored in Alstead and nearby Acworth by Tuesday; phone service was expected to be restored to all but a few houses by the end of the day Thursday.

From Friday evening through Sunday, rainstorms dumped as much as 10 inches on New England and the mid-Atlantic states. In New Hampshire, the storm dropped 10.8 inches in Hinsdale and 10.5 inches in Keene.

The National Weather Service said more flooding could be on the way if rainfall exceeded the 1 to 2 inches predicted today into Thursday. Flood watches were announced for several locations into Thursday.

The state’s director of emergency services, Bruce Cheney, said Department of Environmental Services officials were checking 200 dams in the southwestern part of the state to make sure they were safe. He said crews were using sandbags to reinforce the Warren Lake dam above Alstead. Although the dam suffered little damage when flood waters flowed over it Sunday morning, the inspectors are concerned it would suffer more erosion if it is overtopped again this week.

State police were going door-to-door Tuesday to check on the safety and conditions in many homes. About 50 homes along a badly damaged stretch of Route 123, also known as Forest Road, were difficult to reach or had been partly destroyed; a selectman estimated about a dozen homes, including the Canfields’ were washed away.

A drizzle continued to fall off and on in the area all day, and the weather forecast for the next few days called for more rain.

Some people in the southwestern New Hampshire town of 2,000 were unsure whether they could return home.

“There’s four feet of mud on our first floor,” said Wendy Gendron, who was evacuated with her family and a dozen of her son’s friends from their home early Sunday. “There is no back yard anymore.”

The family was not able to take anything with them, “just the clothes we had on when we left,” Gendron said.

Alstead Police Chief Christopher Lyons said everything in the police station was damaged or lost when water rose to just below the ceiling.

“All of our police records, computers, weapons … everything that was in there is gone. It’s destroyed,” Lyons said.

The station had disaster equipment, including a generator, a ham radio and two-way radios. “We were prepared for something like this to happen, but we never thought” the police station itself would be flooded, Lyons said.

Gov. John Lynch has asked for an emergency federal disaster declaration. Damage assessment teams from the Federal Emergency Management Agency were expected to begin arriving Tuesday.

But prospects looked grim for some. Delvina Kearney, who owns Alstead Village Grocers, said many people who lost all or part of their homes didn’t have any insurance because they were in a flood zone and it was unaffordable.

Linda Pelow, who lives on the same road as the Canfields, was in her house alone Sunday when the floodwaters suddenly surrounded the building.

“I grabbed the puppy and went up to the attic,” she said, adding that no one came to tell her to evacuate.

“It was like watching the tsunami come at me, because all of a sudden, here comes the mud,” she said.

She was lucky; the floodwaters eventually receded and she was able to leave her home, which was still standing.
