In: Remote Sensing of Environment, Vol. 231, 111284, 15.09.2024. Research output: Contribution to journal › Article › peer-review WebThere are two main factors to water clarity of lakes, phytoplankton biomass and suspended sediments (Schrage and Downing, 2004). We were only concerned with phytoplankton concentrations for our study because we didn’t have the equipment to test suspended sediments. As found in other studies, fish have a top-down effect on lentic water clarity. Webinvasion of zebra mussels in 2005 and spiny water ﬂea in 2009 (MN DNR 2024). Notably, a marked increase in water clarity co-occurred with the onset of walleye declines, with Secchi depth changing from an average of 2.5 m from 1977 to 1996 to 3.5 m from 1997 to 2016 (Fig. 2).

WebEstimating Lake Water Clarity Overview A technique was developed by USGS, modeled after Olmanson and others (2001), to estimate Secchi-disk transparency (eSDT) and corresponding estimated trophic state index (eTSI) values based on the Carlson's Trophic State Index (TSI) in inland lakes greater than 20 acres using Landsat satellite imagery. WebAt each site, visual clarity and water colour were recorded together with other field measurements described by Close & Davies-Colley (1990a). Up to three visits were made to each site at baseflow (operationally, flows lower than median). Visual water clarity was measured as the horizontal sighting range of a 200 mm diam. black disk viewed ...

WebThree types of constituents affect water clarity: algae and algal-derived particles; natural, colored organic matter (humic matter); and soil-derived clay and silt particles. In Minnesota lakes, soil-derived turbidity usually is not important, and water clarity most commonly is related to algal abundance. Web1 Nov 2016 · The range of SD values in our calibration dataset (0.15–8.8 m) is suitable for most Minnesota lakes, but with only 9 and 18 measurements > 6 m for Landsats 7 and 8, respectively, more measurements of water clarity in the most oligotrophic waters are needed to determine whether OLI is more accurate than ETM + in measuring water clarity …
