Lakes worldwide are impacted by eutrophication and harmful algal or cyanobacteria blooms (HABs) due to excessive nutrients, including legacy P released from sediments in shallow lakes. Utah Lake (northern Utah, USA) is a shallow lake with urban development primarily on the east side of the watershed, providing an opportunity to evaluate HABs in relation to a gradient of legacy sediment P. In this study, we investigated sediment composition and P concentrations in sediment, pore water, and the…

High Inter‐ and Intra‐Lake Variation in Sediment Phosphorus Pools in Shallow Lakes
Phosphorus (P) release from lakebed sediments may fuel phytoplankton blooms, especially in shallow waterbodies. A primary mechanism that controls internal P loading is the size and chemical
Internal phosphorus loading due to sediment anoxia in shallow areas: implications for lake aeration treatments
Shallow lake sediments may be anoxic despite overlying aerated water. In the current study, we aimed to ascertain the contribution of shallow areas to internal phosphorus (P) loading due to sediment
Sediment Nutrient Flux Rates in a Shallow, Turbid Lake Are More Dependent on Water Quality Than Lake Depth
The bottom sediments of shallow lakes are an important nutrient sink; however, turbidity may alter the influence of water depth on sediment nutrient uptake by reducing light and associated oxic
Sulfur Development in the Water-Sediment System of the Algae Accumulation Embay Area in Lake Taihu
Sulfur development in water-sediment systems is closely related to eutrophication and harmful algae blooms (HABs). However, the development of sulfur in water-sediment systems during heavy algae
Phosphorus fractions in the sediment of a tropical reservoir, India: Implications for pollution source identification and eutrophication
The observed variation in sediment P fractionation indicate the differences in source and characterization of P which is very helpful for implementation of effective management practices in controlling pollution that arises due to phosphorus in this hyper-eutrophic reservoir.
Megafire affects stream sediment flux and dissolved organic matter reactivity, but land use dominates nutrient dynamics in semiarid watersheds
Stream chemistry response of watersheds in a semiarid region of Utah that were affected by a megafire followed by an extreme precipitation event in October 2018 is reported, highlighting how megafires and intense rainfall increase short-term particulate flux and alter organic matter concentration and characteristics.

Response of algal biomass and macrophyte communities to internal or external nutrient loading
Nutrient input from internal and external sources could regulate the variability and abundance of algal and macrophytes in freshwater lakes. This study explores the response of algal and macrophyte


Release rates and potential fates of nitrogen and phosphorus from sediments in a eutrophic reservoir
SUMMARY 1. Nutrients released from lake sediments can influence water column nutrient concentrations and planktonic productivity. We examined sediment nutrient release [soluble reactive phosphorus
Persistent internal phosphorus loading during summer in shallow eutrophic lakes
Nutrient availability, in particular of phosphorus (P), is a key factor for the structure and functioning of shallow lakes, and not least the sediment plays an important role by acting as both a
Internal Phosphorus Loading in Shallow Lakes: Importance and Control
Abstract Decreasing the algal biomass and increasing transparency in shallow, unstratified lakes is usually more difficult than for deep, stratified lakes. Eutrophic unstratified lakes (or shallow,
Characterizing Total Phosphorus in Current and Geologic Utah Lake Sediments: Implications for Water Quality Management Issues
Utah Lake is highly eutrophic with large phosphorous inflows and a large internal phosphorous reservoir in the sediment. There are debates over whether this phosphorous is from geologic or more
Retention and Internal Loading of Phosphorus in Shallow, Eutrophic Lakes
This paper gives a general overview of the nature and important mechanisms behind internal loading of phosphorus (P), which is a phenomenon appearing frequently in shallow, eutrophic lakes upon a

Atmospheric nutrient loading through wet and dry deposition is one of the least understood, yet can be one of the most important, pathways of nutrient transport into lakes and reservoirs. Nutrients,

Total P is increasing over time in the waters of Lake Okeechobee, Florida, but the concentrations do not correlate with external loads. The objectives of this study were to determine: (i) the P flux
Laboratory-determined Phosphorus Flux from Lake Sediments as a Measure of Internal Phosphorus Loading
The use of sediment core incubations are illustrated to assess the effectiveness of an aluminum sulfate (alum) treatment for reducing sediment P release and the effects of sediment resuspension and bioturbation on P release.
The Role of Nitrogen Fixation in Cyanobacterial Bloom Toxicity in a Temperate, Eutrophic Lake
How rapid early summer declines in N followed by bursts of N fixation have shaped cyanobacterial communities in a eutrophic lake (Lake Mendota, Wisconsin, USA), possibly driving toxic Microcystis blooms throughout the growing season is described.

The common carp (Cyprinus carpio) is a globally distributed, benthivorous fish that is capable of substantially altering lake ecology. Although dozens of studies have demonstrated that it has the
