The repository also contains calculated values for quality control for a given lake and year that can also be downloaded in a separate.csv file (JRC_all_no_data_proportions_yearly_95thru15.csv). Lake St. Martin Islands (MB083) - ibacanada.ca (2011) 10,486,660. Interlake Reserves Tribal Council Inc. 2022. These ratios are provided within a secondary.csv file (JRC_all_no_data_proportions_yearly_95thru15.csv) and can be merged efficiently with the full GLCP using the provided R script (combine_data_availability_metrics_with_glcp.R). This process resulted in 10 matched basins (of the original 232,837 matched basins; 0.004%), which were associated with 19 lakes, with missing values for climate variables. Water area, in square kilometers, of permanent water, as defined by Pekel et al.4. As this project involved harmonizing multiple global datasets at different resolutions, our workflow required multiple steps, each of which resulted in a cleaned data subset. Portions of the HydroSHEDS database incorporate data which are the intellectual property rights of USGS (20062008), NASA (20002005), ESRI (19921998), CIAT (20042006), UNEP-WCMC (1993), WWF (2004), Commonwealth of Australia (2007), and Her Royal Majesty and the British Crown and are used under license. Preliminary tests indicated smaller buffers were insufficient to capture large area increases, while larger buffers increased risk of overlapping neighboring lakes (especially in dense lake areas), smaller ponds, or input/output rivers and erroneously increasing lake area totals. The water dam on Fairford River changed the shape of the Lake and changed the Lake into a reservoir (Ballard, 2012). Martin, S. L. & Soranno, P. A. Colonial Waterbird/Seabird Concentrations. These subsets were exported from NASA Goddard Earth Sciences (GES) and Data Information Services Center (DISC) in a netCDF format for local analysis. GEE output was then downloaded locally and aggregated within the R environment. Small numbers of Great Blue Herons and Black-crowned Night-Herons breed on islands within the lake. Center for International Earth Science Information Network Gridded Population of the World Version 3 (GPWv3): Population Count Grid, https://doi.org/10.7927/H4639MPP (2005). For each 5-year increment, human population calculations were performed with a technique similar to the climate data aggregations. is a lake in the Interlake region of Manitoba, Canada on Treaty 2 Land. The first houses to arrive have three bedrooms and are about 1,250 square feet. Lake Manitoba First Nation; Lake St. Martin First Nation; Little Saskatchewan First Nation; Peguis First Nation; . Lake St Martin Genealogy Resources & Vital Records | Manitoba - Forebears 1922-2010 24, 624 (1990). Read more info here. The Fairford River is the only outlet for Lake Manitoba. & Schmitt, O. Estimating the volume and age of water stored in global lakes using a geo-statistical approach. Lake polygons were uploaded and imported into Earth Engine as shapefiles. [citation needed] The Manitoban government decided to divert the water flow to Lake St. Martin First Nation to lessen the impact of flooding on Winnipeg and other non-Indigenous homes and farm lands (Thompson, 2015). Note that for the purposes of these data 2015 ends on October 31, consistent with the JRC data. The majority of HydroLAKES lakes are defined as uncontrolled lakes (99.5%), with the remainder identified as reservoirs (0.47%) and controlled lakes (0.03%). Practical experience in the numerical dangers of heterogeneous computing. Article Flooded out to save Winnipeg, Lake St. Martin residents now feel Contributed to writing R Scripts: M.F.M., S.G.L., M.R.B., A.N.C. Finding the Right Balance. Second, zeros could represent real missing (NA) values from incomplete LANDSAT coverage for certain locations and years. The Lake is situated between Lake Manitoba and Lake Winnipeg. We identified a minority of lakes that were unable to be included in the final data product. Land surface precipitation in MERRA-2. The racial makeup of the village was 100.00% White. The Fairford River is the only outlet for Lake Manitoba. Bull. Scientific Data Therefore, we have approximately 99% accuracy in terms of detecting water within a lake for the global lakes considered in the GLCP. The Tao of open science for ecology. Because it is unrealistic for these 1,304 lakes (average total area: 2.39 km2) to be influenced by near continental-scale climate and human population forcings, we excluded these lakes from further processing. Sint Maarten population is equivalent to 0.00055% of the total world population. Across all buffers and years included, the ratio of observed to expected values had an approximate mean of 0.9 (Table2). 1916 Manitoba, Saskatchewan & Alberta Census (1916) An index to and images of registers recording over 1.8 million people who live in the states, including details on their age, race, immigration details, place of birth, family relationships and more. This page was last edited on 8 April 2023, at 14:53. These 10 basins ranged in size from 1.1 to 181.7 km2 with a median areaof 76.5 km2. To evaluate how lake waterClass areas fluctuated with various buffer sizes, we calculated lake waterClass areas for 1995, 2000, 2005, 2010, and 2015 with 30m, 60m, 90m, and 120m buffers. Here we detail the steps taken to integrate the HydroLAKES, HydroBASINS, JRC, climate, and human population datasets described above. Percent differences were very low for each variable (TableS4) and are likely not significant for most future applications. With this basin matching scheme, there is potential for some lakes to be assigned to basins which are larger than their actual basin. Google Scholar. Water Resour. 53 Herring Gull nests were noted during the same survey. km land loss around this lake in the year of 2011. To match lakes with their equivalent basins, we performed spatial joins for the lake shapefiles and basin shapefiles to identify the smallest basin that enclosed a lake in its entirety. The Official Lake St. Martin First Nation Facebook Page Aside from blank values, numerous basins have population estimates as decimal values. Socio-Economic Survey Lake Manitoba and Lake St. Martin Outlet Channels project, 7th Annual Youth Fundraising Golf Tournament June 8, 2023, Congratulations to the newly elected Peguis Chief & Council, On-Call Schedule for Emergency Management, Nursing, Jordans Principle and Wellness, The Narrows 49 2,613.30 hectares (6,457.6 acres), The Narrows 49A 982 hectares (2,430 acres). 2), this is largely an artifact of LANDSAT coverage missing from 199619984. Results were exported as.csv files to Google Drive, then downloaded for local analysis using R. R scripts for data aggregation of climate variables (04_post_gee_processing_temp.R, 05_post_gee_processing_precip_sum.R, 06_post_gee_processing_precip_average.R)24,25,35 are available on the EDI GLCP repository27 within the entity glcp.tar.gz. Death toll in flooded-out Manitoba First Nation hits 92 as evacuees To help bridge the distance between available global water-related data sources and potential users with a range of computational capacities and experiences of managing large, disparate data sources, we integrated existing long-term datasets for lake locations and characteristics, water surface area, climate, and human population to create the unified Global Lake area, Climate, and Population (GLCP) dataset. Dowle, M. & Srinivasan, A. Data.table: Extension of data.frame (2019). Flooding First Nations and Environmental Justice in Manitoba: Case Studies of the Impacts of 2011 Flood and Hydrodevelopment in Manitoba. Lake Manitoba - Lake St. Martin - Regulation Review - Report. Governments knowing First Nations are most at risk need to invest in flood protection for these communities. ISSN 2052-4463 (online). The resulting yearly data were saved as rasters. Thank you for visiting nature.com. This Portage Diversion brought water from the Assiniboine River to an entirely different watershed through digging a 29 km long channel to Lake Manitoba. Hydrol. While recent efforts to capture global scale changes have created opportunities to address water quantity questions as they relate to human demand and climate variability, many researchers, especially those focused at local scales, may be limited by the computing infrastructure and researcher skill set required to integrate existing environmental datasets. Sint Maarten Population (2023) - Worldometer In instances of high variation, this process would identify specific outliers that could be explained by local anomalies (e.g., extensive drought, ENSO). Lehner, B. Geophys. The Interlake Reserves Tribal Council Inc. (IRTC)consists of a partnership of six (6) Manitoba Interlake communities working together to advance our collective well-being of our members. Nature 540, 418422 (2016). H. Woo and Stephen L. Katz for reviewing R scripts. Thus, Lake St. Martin became a reservoir. Assessing Land Loss from Flooding in the Lake St. Martin Basin in Kara. Google Earth Engine: Planetary-scale geospatial analysis for everyone. The Lake St. Martin impact structure (Manitoba, Canada): A simulated Aside from adding new variables, the framework used to produce the GLCP is flexible enough to incorporate new lake and basin shapefiles (e.g., GLOWABO2). Calculated ratio of no_data_km2 derived area to permanent_km2 derived area. Provided by the Springer Nature SharedIt content-sharing initiative, Scientific Data (Sci Data) Spatial variation among lakes within landscapes: ecological organization along lake chains. The GLCP contains over 1.4 million lakes of at least 10ha in surface area, with annual surface area (identified as permanent or seasonal water) from 1995 to 2015, paired with annual basin-level temperature, precipitation, and population values. Pap. Figure 1: Flood water levels in 2011 and 2012 at Lake St. Martin Source: Province of . J. Hydrol. All Google Earth Engine and R scripts are available from the Environmental Data Initiative GLCP repository27 within the entity glcp.tar.gz. WINNIPEG -- Some residents of Lake St. Martin have been waiting nine years to return home, since a flood . The outflow for Lake St. Martin exits through Dauphin River and into Lake Winnipeg, at a lower rate than the water comes in. Plumbing the Global Carbon Cycle: Integrating Inland Waters into the Terrestrial Carbon Budget. In some cases we sampled an additional lake to ensure that a full sample of 250 Hylak_ids was achieved when rounding would otherwise have led to a sample size smaller than 250. Third, zero area values could represent a mis-identified HydroLAKES polygon (i.e., not an actual lake in that location)36. Weathers, K. C. et al. 30, 16431664 (2017). 3 In addition, an inadvertent bias in the disaster relief services and.

While numerous potential thresholds exist, the authors encourage reporting any data metric thresholds used in GLCP applications, so as to maintain future reproducibility of GLCP analyses. Res. This is traditional land for three First Nations (Lake St Martin First Nation, Pinaymootang First Nation and Little Saskatchewan First Nation), but this site is not well known by ornithologists and more bird surveys are needed. While other data sources in this project are annual, the global population data we used, which was the current best available at the global scale, was for 5-year increments (1995, 2000, 2005, 2010, 2015). https://doi.org/10.1038/s41597-020-0517-4, DOI: https://doi.org/10.1038/s41597-020-0517-4.
