SUMNER — Rocks that mysteriously appeared on top of the dam at the outlet to Labrador Pond last summer are causing concerns for some.

Waterfront owner Larry O’Rourke told selectmen Dec. 22 that he had seen the water rise a foot or more after a big rainstorm, and the crawl space under one of his buildings has been flooded.

Road Commissioner Jim Keach said the water level was higher than culverts on Labrador Pond Road, which made them impossible to drain. “The water level is making the bank erode near the road,” he said.

O’Rourke said he thinks the spillway is too narrow as well.

Board Secretary Cyndy Norton said Dana Murch of the Department of Environmental Protection said the ownership of the dam needed to be established.

Selectmen’s Chairman Mark Silber said the town built the dam and owns it. He said when the bridge was built 10 or so years ago on the dirt portion of Valley Road, the dam was built to DEP specifications.

Fire Chief Bob Stewart was concerned that if the water level went down, the department’s dry hydrant for filling the Fire Department tanker wouldn’t be deep enough.

Silber said when the bridge was built, that was all taken into consideration and the problem is that rocks seem to be growing on top of the dam each year, raising the water level.

Silber asked Norton to contact abutters to the dam and request permission for large machinery to cross their land for access to the dam for rock removal. It was noted that people are not to be placing rocks on top of the dam to raise the water level in the pond.

Another concern at the meeting was icy roads. Winter roads contractor Clifford Lowe said he was having trouble getting salt and rocks in the sand spread on roads were too large. He said he would try to get the better sand for use on Route 219 as faster traffic might make the larger rocks fly into windshields.

School bus travel on Jack Road was discussed, and it was agreed that the road is just too steep for a bus to travel on to pick up the one student there.

Silber suggested contacting the parent to see if they could bring the child to the bottom of the hill. The Hartford-Sumner school principal had asked the board to discuss the issue because the bus route coordinator for Regional School Unit 10 had looked at the situation and agreed it was not safe for the bus.

In other matters, the board discussed revising its Emergency Operations Plan in light of experience gained from the fall tornado.
