A water temperature history is provided below. Water temps peak end of July.

The Twain Harte Lake officially opens to members and guests Memorial Day weekend  and closes Labor Day weekend . No lifeguards are available outside of that period, but swimming and lake use continues into Fall.  The 2008 season began a new lake admission methodology. Lake entry by electronic debit to member's account is required for each person--adult or child.  All guests must be accompanied by members, unless guest is using member's cabin.

GENERAL INFORMATION: Twain Harte Lake is a private 7-acre stream-fed lake on 56 acres of buffer land at the west end of the village. It has a long sandy beach, two water slides, children's swings, diving boards, restrooms at west and east ends, a Snack Shack--and, a serene setting amongst large Sugar Pines. The lake is stocked with fish for children under 16 years to fish (limit 3 fish)--so bring the fishing rod!

No food or drinks may be brought into the lake property or consumed there. Only water in clear bottles is allowed. Food purchased at the Snack Shack must be eaten west of the beach area in designated eating areas.  There is no smoking anywhere inside the lake property. Some visitors go to the parking lot where they eat from their car tailgates and smoke at a 'smoke bench' provided with a butt can.

The Snack Shack provides a wide variety of foods, non-alcoholic drinks, and ice cream and icees.

Lifeguards are on duty from Memorial Day weekend until Labor Day weekend. Annual events, such as the 4th-of-July BBQ, the Summer Water Carnival, and twice-weekly Bingo are just some of the planned lake activities. See 'Lake Events' below.

Twain Harte Lake is a private lake, with a membership of local Twain Harte property owners, for use by their family, friends or guests. Membership fees and annual dues are administered by itís Board of Directors elected by the membership according to the By-laws. In the late 2008 Season, 50 new memberships were filled from the waiting list. Presently no more memberships are available, and new openings continue to be filled from a $50/year fee waiting list. Membership thus increased from 750 to 800 member-families.
