Data from: Effects of macrophytes on lake‐water quality across latitudes: a meta‐analysis
Macrophytes are widely recognized for improving water quality and stabilizing the desirable clear‐water state in lakes. The positive effects of macrophytes on water quality have been noted to be weaker in the (sub)tropics compared to those of temperate regions. We conducted a global meta‐analysis using 47 studies that met our set criteria to assess the overall effects of macrophytes on water quality (measured by phytoplankton chlorophyll a concentration, total nitrogen concentration, total phosphorus concentration, Secchi depth, and the trophic state index) and to investigate how these effects correlate with latitude using meta‐regressions. We also examined if the effects of macrophytes on lake‐water quality differ with growth form in (sub)tropical and temperate areas by grouping the data and then comparing the effect sizes. We found that macrophytes significantly reduced phytoplankton chlorophyll a concentration, total nitrogen concentration, total phosphorus concentration, as well as the trophic state index, but they did not have a significant overall effect on Secchi depth. The effects of macrophytes on reducing phytoplankton chlorophyll a concentration, total nitrogen concentration, and the trophic state index did not differ with latitude. However, the reduction of total phosphorus concentration was greater at lower latitudes. We showed that at lower latitudes, the positive effects of macrophytes on water quality are similar to or greater than those at higher latitudes, thus challenging the prevailing paradigm of macrophytes being less effective at enhancing lake‐water quality in the (sub)tropics. Furthermore, our data showed that the macrophyte effects vary by growth forms, and the growth forms that positively affect water quality differ between the (sub)tropical and temperate areas. We showed a lack of significant macrophyte effects in surveys within and outside macrophyte stands, suggesting difference in the sensitivities of study designs or possibly weaker effects of macrophytes in lakes compared to experimental settings.
Data from: Integrating water quality monitoring and diatom community trends to determine landscape-level change in protected lakes.
<p>These data represent water quality measurements and diatom counts from surface sediments collected from lakes in five National Park units in the Great Lakes Region (USA) between 2005 and 2018. Water quality measurements were made three times annually during the growing season; data are presented as growing season means. Surface sediment samples were collected from the same lakes every 3-5 years over more than a decade to analyze diatom community turnover. Diatom data are presented as proportions relative to total diatom counts in each sample; only taxa occuring at 2% or greater in a given park were included. </p>

DEEP Lakes Grant Program water quality assessment, CT, 1937-2006
“The water quality of lakes in Connecticut has historically been assessed by the CTDEP using best professional judgment as a follow-up to citizen complaints. The CTDEP possesses a number of lake technical studies (dredging feasibility studies, drainage studies, and diagnostic/feasibility studies) that were completed by local municipalities and lake associations using funding provided through the Connecticut Lakes Grant Program. Many of these reports contain data regarding lake water quality and limnological and watershed characteristics."
Tip of the Mitt Watershed Council Comprehensive Water Quality Monitoring Program lake chemistry, MI, intermittent years between 1987-2010
The Comprehensive Water Quality Monitoring Program was launched by Tip of the Mitt Watershed Council in 1987, with subsequent field data collection in 1992, 1995, 1998, 2001, 2004, 2007, and 2010. Initially, physical and chemical data were collected on 10 lakes but the program has progressively expanded and, as of the 2010 field season, 143 samples were collected from 60 sites on 55 lakes and streams. Typically, data for nine parameters (temperature, dissolved oxygen, pH, conductivity, clarity, total phosphorous, total nitrogen, nitrate-nitrogen, and chloride) are collected at the surface, middle and bottom of the water column in each water body. This highly-accurate water quality data for lakes and rivers in Northern Michigan, collected consistently for the last 20+ years, have been compiled into a single database that can be used by staff to evaluate aquatic ecosystem health, examine trends within or among water bodies, and identify specific problems.

Lake Wallenpaupack Water Quality Evaluation, PA: water chemistry, 1980-2012
PPL Corporation created Lake Wallenpaupack in 1926 and uses water from the lake to generate hydroelectric power… The Lake Wallenpaupack Watershed Management District (LWWMD) was established in 1979 to preserve and protect the water quality of Lake Wallenpaupack. The LWWMD Board of Directors consists of representatives of the business community, local government, and PPL Corporation. PPL Corporation has funded a yearly water quality monitoring program for Lake Wallenpaupack since the early 1980s. …The water quality of Lake Wallenpaupack has been monitored on a yearly basis from 1980 through the present. In general, the water quality of Lake Wallenpaupack has improved since 1980. Over the past several years, total phosphorus levels in the lake have been stable and consistently lower (better) than 1980 total phosphorus levels. Chlorophyll a and transparency levels were also better than the 1980 levels for many years. However, chlorophyll a have been increasing in recent years, to a peak in 2002, while transparency has been decreasing (becoming less favorable). The main water quality parameters that were evaluated as part of this study include dissolved oxygen, phosphorus, nitrogen, chlorophyll a, transparency, pH, alkalinity, phytoplankton, and zooplankton
Michigan Department of Environmental Quality, Michigan's Lake Water Quality Assessment Program (MI-LWQA), 2001-2010
The sampling methodology and program was designed to replicate the methods used historically by MI-DEQ to sample inland lakes in the 1970-1980’s. Each year, lakes were selected randomly from 7-10 major watersheds in MI. Watersheds were monitored in a 5-yr cycle in conjunctions with current MI-DEQ water quality activities. Lakes > 25 acres were chosen that had public boat access.

This data set includes bidirectional reflectance (BDR) spectra and water-quality data of floodplain lakes of the Solimoes and Negro Rivers in the central Amazon basin, Amazonas, Brazil. Samples and measurements were collected during July 2000 to August 2000. Bidirectional reflectance factors were recorded, at 3 nm intervals from 400 to 900 nm, concurrently with in situ measurements of water temperature and Secchi depth, and collection of samples for analysis of optically active components including total suspended solids, chlorophyll, and dissolved organic carbon (DOC).The lakes sampled were in the low-lying varzea of the Solimoes River ("varzea" is the local name for the floodplain formed by the overflow of white-water rivers) and igapo ("igapo" is the local name for the floodplain formed by the overflow of black-water rivers) of the Negro River.There are two comma-delimited data files with this data set.
