Environmental Factors
The Lahontan Cutthroat trout fishery at Pyramid Lake draws many anglers from the Reno area and beyond. Sale of fishing licenses and boating permits is a large source of revenue for the tribe. Prior to the construction of Derby Dam and the diversion of water from the Truckee River for irrigation, the lake supported a commercial fishery which was an even larger revenue source for the tribe.
Historically water levels have been declining in Pyramid Lake; in addition, water quality has been impacted by upstream discharges including point and non-point sources. A number of studies have been conducted on Pyramid Lake including application of the DSSAM hydrological river model to examine nitrogen, reactive phosphorus, dissolved oxygen and other water quality parameters.

Famous quotes containing the word factors:
“The goal of every culture is to decay through over-civilization; the factors of decadence,—luxury, scepticism, weariness and superstition,—are constant. The civilization of one epoch becomes the manure of the next.”
—Cyril Connolly (1903–1974)
