About Trinity County
Trinity County covers about 3,200 square miles and has about 16,100 residents. Weaverville is the county seat and the largest community, and the county has no incorporated cities. It is rugged, forested mountain country along the Trinity River, with Trinity Lake and Lewiston Lake, part of the Shasta-Trinity National Forest, and the Trinity Alps Wilderness, the second largest wilderness in California. Communities include Weaverville, Hayfork, Lewiston, Douglas City, Junction City, Trinity Center, Hyampom and Big Bar.
- Mountain and forest country. Steep, wooded parcels with long driveways are common, which is where a line pump earns its keep.
- Hot summers, snowy winters. Populated areas often reach 85 to 100°F in summer, while snow falls above about 3,300 feet, so the pour season runs from spring to fall.
- Wide distances. About 16,100 people live across 3,200 square miles, and State Routes 299, 3 and 36 are the main roads. We plan travel, set-up and hose runs ahead, and pours here are scheduled in advance.
- Lakes, ranches and rural properties. Trinity Lake and Lewiston Lake draw visitors, and the Hayfork Valley has ranches and farms, so cabin, shop and rural foundation work is common.
