Lake Tahoe is undergoing the initial stages of culturaleutrophication due to human alteration of the airshed andwatershed. The lake's switch from nitrogen (N) to phosphorus (P)limitation has been attributed primarily to atmospheric Nloading. This places an increased importance on controllingwatershed movement of P to the lake. A stream water qualitymonitoring data set consisting of nine streams in the Lake Tahoebasin has been analyzed to characterize the spatiotemporalvariation of P delivery to… 
The importance of small urbanized watersheds to pollutant loading in a large oligotrophic subalpine lake of the western USA
It is suggested that small, urbanized watersheds and intervening zones are disproportionately important contributors of nonpoint source pollution, including nutrients and suspended particles, in the Tahoe basin.
Retention of suspended sediment and phosphorus on a freshwater delta, South Lake Tahoe, California
The Upper Truckee River and Trout Creek, two major tributaries inflowing to Lake Tahoe, join to form what was historically the largest wetland in the Sierra Nevada mountain range that separates
Suspended sediment dynamics associated with snowmelt runoff in a small mountain stream of Lake Tahoe (Nevada)
The Lake Tahoe basin is experiencing an environmental decline that is partly due to sediment intakes from its tributaries. Many studies have estimated suspended sediment loads in these streams with a
Bioavailability of phosphorus transported during storm flow to a eutrophic, polymictic lake
The bioavailability of catchment-derived particulate phosphorus (PP) to lentic phytoplankton was investigated. Two stream inflows to Lake Rotorua (Bay of Plenty, New Zealand) were sampled during
Soil Phosphorus Speciation and Availability in Meadows and Forests in Alpine Lake Watersheds With Different Parent Materials
In the Lake Tahoe Basin in California and Nevada (USA), managing nutrient export from watersheds into streams and the lake is a significant challenge that needs to be addressed to improve water
A deterministic model for lake clarity; application to management of Lake Tahoe (California-Nevada), USA
This dissertation has as its goal the quantitative evaluation of the application of coupled hydrodynamic, ecological and clarity models, to address the deterministic prediction of water clarity in
Effects of discharge level on the load of dissolved and particulate components of stream nitrogen and phosphorus from a small afforested watershed of Japanese cypress (Chamaecyparis obtusa)
The behavior of dissolved and particulate components of stream nitrogen (N) and phosphorus (P) were measured for 2 years in a small mountainous watershed covered primarily with a plantation forest of
Evaluation of Effectiveness of Three Types of Highway Alignment Best Management Practices for Sediment and Nutrient Control
Lake Tahoe is renowned for its natural beauty. Regrettably, water clarity is declining at a rate of approximately 1 ft per year. This degradation has been attributed in part to nonpoint pollution


Nutrient transport in surface runoff from a subalpine watershed, Lake Tahoe Basin, California
The watershed of Ward Creek, a tributary to oligotrophic Lake Tahoe in the Sierra Nevada, has been investigated since 1971 with the objective of improving our knowledge of processes of nutrient and
Transport and Transformation of Phosphorus in a Forest Stream Ecosystem
Although variability characterizes most aspects of P dynamics in Bear Brook, processing of P is consistent and monthly transport patterns or annual mass balances generated from only 1 yr of record may lead to erroneous conclusions on stream ecosystem function.
Long-term change in Lake Tahoe (California-Nevada, U.S.A.) and its relation to atmospheric deposition of algal nutrients
Bounds for the doubling times of the TN pool and the TN: TP ratio demonstrate that loading is fast enough to cause the observed changes, and suggest that interannual variability in nitrate and total acid-hydrolyzable phosphorus is large enough to disguise trends of the expected magnitude.
Origins and scale dependence of temporal variability in the transparency of Lake Tahoe, California–Nevada
Secchi depth has been measured in Lake Tahoe an average of every 12 d since July 1967. Because of the unusual clarity of the lake, Secchi depth measurement is responsive to small changes in
Decadal, Interannual, and Seasonal Variability in Enrichment Bioassays at Lake Tahoe, California–Nevada, USA
The response of Lake Tahoe water to macronutrient supplementation has been assayed with inorganic 14C uptake since the 1960s, and on the decadal and annual scale, an effect of spring mixing depth on the size of the bioassay response could be observed.
River Loads Underestimated by Rating Curves
Statistical considerations show that the sediment, solute, or pollutant load of a river is likely to be underestimated by methods in which unmeasured concentrations are estimated from discharge using
