Texas 2022 water clarity and color (FLAMe and Sentinel-2)

Alternate Identifier:

DOI PLACE HOLDER

Abstract:

Water clarity and color were determined for six reservoirs using rapid spatial surveys from a sensor equipped boat and concurrent Sentinel-2 satellite imagery across Texas during drought conditions between the months of July and August 2022. From west to east, these systems include Red Bluff Reservoir, O.H. Ivie Lake, Lake Arrowhead, Lake Brownwood, Lake Waco, and Lake Bonham. For the water year leading up to the sampling dates, the precipitation ranged from 182 mm in Red Bluff Reservoir to 1036 mm in Lake Bonham. A total of 254 km of boat path were covered across the six reservoirs with a mean boat speed of 19.17 km/h. The data for this study covers three spatial approaches 1) along the boat path 2) longitudinal transects from dam to river arm and 3) whole system. For the boat path, data variables include turbidity measured continuously with a YSI EXO2 sonde, Secchi disk depth predicted from the turbidity values, normalized difference turbidity index (NDTI), and dominant wavelength. For both the longitudinal transects and whole system data, variables include the two remotely derived measures of clarity and color, NDTI and dominant wavelength. Data is also categorized by zone as either "arm" (reservoir arm) or "body" (main body) determined by a 4m depth threshold to compare between zones.

Data Entities
Data Table Name:	sentinel2flame_meanvalues
Description:	Data used for the 2-way analysis of variance. The data along the boat path is grouped by reservoir system and zone. For each reservoir (n =6) there is the mean of points in the lacustrine zone and the mean of points in the riverine zone. Lake Brownwood and Lake Waco have two distinct river arms making for a total n = 14. Variables include water clarity as measured by turbidity, predicted Secchi disk depth, and normalized difference turbidity index along with color determined by dominant wavelength. Trophic state index determined from Secchi depth is also included.
Data Table Name:	flame_points_sen2cor
Description:	Data for points along the boat paths, includes FLAMe (sensor-equipped boat survey) data such as measured turbidity, predicted Secchi depth, and trophic state index from Secchi, along with Sentinel-2 Level-2 sen2cor corrected band values (R,G,B) and the calculated variables of ndti and dominant wavelength.
Data Table Name:	flame_points_acolite
Description:	Data for points along the boat paths, includes FLAMe (sensor-equipped boat survey) and Sentinel-2 ACOLITE corrected Level-2 water product band values (R,G,B) and ndti
Data Table Name:	systemwide_sentinel2
Description:	Data values for every cloud-free water pixel for each reservoir system on the clear image day (all on sampling date except for Lake Waco and Lake Arrowhead). The Sentinel-2 Level-2 Collection (sen2cor data product) was combined with the Sentinel-2 Cloud Probability data product in Google Earth Engine to exclude clouds/cloud shadows and the modified normalized difference water index was used to only include water pixels for each system. Data includes dominant wavelength and normalized difference turbidity index and was categorized by reservoir zone.

Description:

We conducted rapid spatial surveys of surface water in six reservoirs (Lake Bonham, Lake Waco, Lake Arrowhead, Lake Brownwood, O.H. Ivie Lake, and Red Bluff Reservoir) between July 15-August 12, 2022 using methods similar to those of the Fast Limnology Automated Measurement (FLAMe) platform used in Crawford et al. (2015) and Loken et al. (2018). These surveys were timed concurrently with a Sentinel-2 satellite image acquisition except for Lake Brownwood which was within 24 hour (survey on August 6, 2022, satellite flyover on August 7, 2022). Turbidity measured along the boat path corresponded positively with normalized difference turbidity index, NDTI (Lacaux et al. 2007) using similar methods as Powers et al. (2023). Secchi depth was predicted along the boat path using the relationship between log(turbidity) and log(Secchi) determined from all the reservoirs in the 2012 and 2017 National Lakes Assessment. Dominant wavelength was calculated using chromaticity analysis as described in Lehmann et al. (2018) and Yang et al. (2022) along the boat path, for longitudinal transects, and for the whole system. The whole system calculation of dominant wavelength and NDTI was conducted in Google Earth Engine (GEE) where the Level-2 Sentinel-2, ee.ImageCollection("COPERNICUS/S2_SR_HARMONIZED") collection was combined with the Sentinel-2 Cloud Probability product, ee.ImageCollection("COPERNICUS/S2_CLOUD_PROBABILITY") to exclude clouds. The modified normalized difference water index (Buma et al. 2018) was used to mask out non-water pixels. Cloud-free, water pixels were clipped within the lake polygon boundaries and exported as TIFs to conduct analysis in R. Within R, bounding boxes were used to separate reservoir arms from reservoir main bodies determined by a 4 meter threshold. Means were taken for clarity and color data variables (measured turbidity, predicted Secchi depth, NDTI, and dominant wavelength) for each zone within each lake (n = 14). A two-way analysis of variance (variable~zone + system) and Tukey's post-hoc analysis was conducted to test for differences. Level 1 Top-of-Atmosphere images were also downloaded for the lakes and dates of interest from the Copernicus Data Space Ecosystem and ACOLITE atmospheric correction was applied to produce both Level-2 surface reflectance and Level-2 water products. Points along the boat path and the longitudinal transects from dam to river arm were queried within R for both the cloud masked product from GEE and the ACOLITE L2W. Band values were extracted from using the extract function from the terra package (Hjimans 2024).
