NOTES ON FISHES FROM STREAMS AND LAKES OF NORTHEASTERN 
CALIFORNIA NOT TRIBUTARY TO THE SACRAMENTO BASIN. 
By CLOUDSUEY RUTTER, 
Naturalist, United States Fish Commission Steamer Albatross. 
The fishes forming the basis of the following report were collected in 1898 and 
1899 while studying the distribution of the fishes of the Sacramento Basin. The 
collection was studied at Leland Stanford Junior University, where special facilities 
for study and comparison were afforded by the ichthyological museum. 
The localities from which the collection was obtained represent four basins, now 
distinct, though at one time probably tributary to Lake Lahonton. These basins 
are Grasshopper Lake, Eagle Lake, Honey Lake, and Truckee River. 
Grasshopper Lake is an alkaline pond, with no outlet, at the southern end of 
Grasshopper Plains, in Lassen County, and contains no fishes. A species of Agosia 
was found to be abundant in a spring emptying into the lake. 
Eagle Lake also has no outlet, the lowest point in the surrounding watershed 
being over 50 feet above the surface of the lake. Its water is slightly alkaline, 
though very clear, and near the shore supports thick aquatic vegetation. Only two 
species of fishes were obtained, the Eagle Lake white-fish ( Rutihis olivaceus) and 
a sucker ( Chasmistes chamberlaini) here described as new. A trout is known to 
inhabit the lake, but none was obtained. 
Two streams were fished in Honey Lake Basin — Willow Greek and Susan River. 
The former rises at the lowest point in the Eagle Lake watershed, and its upper 
part is a rough mountain stream. It was fished about 15 miles north of Susanville, 
where it passes through an extensive meadow. Susan River rises on the eastern 
slope of Lassen Butte, and above Susanville is a mountain torrent. Its lower part 
lies in the plains adjacent to Honey Lake and is dry during part of the year. 
Collections were made in three streams of Truckee Basin — Little Truckee River, 
Sage Hen Creek, and Prosser Creek. The former, a considerable stream, 15 to 30 
feet wide, with very rocky bottom, drains Webber Lake and Independence Lake, 
and was fished a short distance below the outlet of the latter. Sage Hen Creek is 
tributary to Little Truckee River. It is but a small stream, flowing through a nar- 
row wooded valley. Prosser Creek is tributary to Truckee River and drains the 
table-land north of Truckee. It was fished near Prosser Bar, where it is a meadow 
stream from 6 to 10 feet wide and 6 inches to 6 feet deep. 
The fish fauna of these waters is very limited. Three species are described as 
new. The collection consists of 9 native and 2 introduced species, distributed as 
follows: One species, Agosia robusta, is common to three of the four basins and is 
probably to be found in the other basin, Eagle Lake. Another, Rutilus olivaceus, is 
found in all the basins except that of Grasshopper Plains. Chasmistes chamberlain i ,
