A week after a storm washed out roads and flooded properties throughout the region, some places were still underwater Saturday.

Different parts of Winchester Speedpark were still submerged under 2 to 4 feet of water, according to owner Deb McNamara. The flooding swept away picnic tables, portable toilets and fencing, she said, in addition to ruining jumps and creating ravines in the track.

The water is receding, McNamara added Saturday, and she said she believes the motocross track on Keene Road will be able to resume hosting events again this coming weekend.

She said the flooding began on Sunday, July 18. That Monday, the water continued to rise, and she needed a boat to access the speedpark’s office.

A slow-moving storm dumped more than 5 inches of rain over the Monadnock Region between July 17 and 18, damaging infrastructure and inundating basements, yards, lakes and rivers with water.

At Otter Brook Lake, the beach, picnic area and part of the disc golf course were still deluged Saturday. A sign posted at the gate declared the area closed due to flooding, but pedestrians could still walk down to the water’s edge.

Meanwhile, much of the area surrounding Surry Mountain Lake — including the beach, parking lot and playground — remained underwater, with only the roof of a picnic pavilion visible from the main road.

Both the Otter Brook and Surry Mountain Lake recreation areas will be closed until further notice, according to a U.S. Army Corps of Engineers Facebook post.

Christie Baker, a project manager with the Army Corps of Engineers who works on the Otter Brook and Surry Mountain dams, said that the parks and their facilities were designed to be flooded as necessary to keep the water under control. She said that while water is receding, there’s no telling when the parks will be dry enough to open up again, noting that they may not even reopen this season.

“The reservoirs are decreasing. It’s going in the right direction, but I can’t predict [when the parks will open],” she said Monday morning. “It will completely depend on how much rain we receive. Once the water does recede back to normal levels, we have no idea what … debris clean-up we’re going to have.”
