[6] Among these the Chalybeate Spring was enclosed in a cement basin and gave about 5 US gallons (19 L; 4.2 imp gal) per minute of carbonated water at a temperature of 63 °F (17 °C).

[10] The resort grew to include a hotel, cottages, dance hall, store, stable and other facilities.

The surrounding forests are fairly alive with all kinds of game, such as deer, rabbits, squirrels, grouse, quail, etc.

The springs, of which we have four, emiting [sic] mineral water of different kinds, are unequaled for the cure of paralysis, rheumatism, dropsy, gout and kindred diseases.The buildings of the town, or springs, consist of a fine, largo hotel, conducted by the Allen Brothers; also thirty-four cottages, which are rented to guests at a reasonable rate; a stable under the management of the Lee Brothers; a neat cigar, liquor and billiard saloon, owned by Seube & Ällen; Mr.Pryot's store of general merchandise; a barber shop and bath rooms, and a town hall.

[11]An advertisement from 1880 described Allen Springs as "A fine summer resort for tourists and invalids.

The route from Sacramento and San Francisco is by railroad to Williams, thence by stage (daily) 40 miles over a romantic mountain road.

As of 1881 there was a daily line of stages from Lakeport to the west via Upper Lake, and from Williams to the east.

The water was claimed to be good for kidney affections, dyspepsia, rheumatism, dropsy, general debility, skin diseases, female complaints, ague, paralysis and erysipelas.

[14] Early in the 20th century high waters one winter washed away some of the cottages and the resort was closed.

[1] As of 1911 water that was formerly bottled, which came from a spring on the steep canyon side opposite the hotel, was piped across the creek to a drinking shed.

[9] A real estate advertisement in 2021 for part of the resort said "Creek is running & nature has taken over".
