[3] Winchester Lake State Park lies south of the city.

While considering the possibilities, an individual looked at the stack of Winchester rifles at the door and suggested the name, which was approved.

[11][12] The mill was operated by Boise Cascade for its final five years; its closure followed a fire which destroyed much of downtown Winchester in November 1964.

[13][14][15][16] A one-half mile (0.80 km) outside of town is Winchester Lake State Park, planned in 1966[17] and established in 1969.

[19] Water quality issues at the lake[20][21] were addressed with the installation of aeration units in 2002.

[22][23] According to the United States Census Bureau, the city has a total area of 0.18 square miles (0.47 km2), all of it land.

The city is two miles (3.2 km) west of U.S. Route 95, which connects it to Craigmont to the east and Lewiston to the northwest, via the Lapwai Canyon.

Until 1960, US 95 was routed through Winchester on this spur and descended Culdesac Hill (46°19′55″N 116°37′59″W / 46.332°N 116.633°W / 46.332; -116.633), considered the worst of the three major grades (White Bird, Lewiston), all of which were extremely twisty.

[32] The new route through Lapwai Canyon was built in three years and reduced the distance by over 4 miles (6.4 km) and saved 25 minutes of driving time.

[36] The timber trestles of the former Camas Prairie Railroad are visible throughout the area.

An epilogue featuring host Robert Taylor and Lester Shadduck, the mayor of Winchester, was shot on location in 1967.
