Community science-based monitoring reveals the role of land use scale in driving nearshore water quality in a large, shallow, Canadian lake. Lake Reserv Manage. 37:431–444. As shorelines and watersheds become increasingly developed, lake condition declines due to nutrient enrichment, excess algae growth, and contaminant loading. Lake Scugog, a large shallow lake in southern Ontario, Canada, is no exception, and has been experiencing increased urban development in its agriculture-dominated watershed over the last few decades. By applying a 3-pronged co-production model (stewardship group, watershed authority, and university laboratory), a nearshore water quality monitoring program was implemented using a community-science approach. Nearshore water samples were collected over 3 years (2017–2019) by trained community scientists. We found strong relationships between water quality parameters and land use, at the buffer and subcatchment scale. The strength of the land use relationships varied by parameter and scale, where chloride was significantly predicted by buffer land use, and phosphorus was explained by development at the subcatchment scale. Based on the high rate of participation compliance, the community science approach proved to be effective for capturing spatially explicit water quality data, which allowed us to establish current baseline conditions in Scugog’s nearshore zone. Future watershed management should consider both scales of land use, but prioritize restoration efforts on the scale that corresponds to their specific water quality goals.","PeriodicalId":18017,"journal":{"name":"Lake and Reservoir Management","volume":"37 1","pages":"431 - 444"},"PeriodicalIF":1.5,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45563905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effect of management on water quality and perception of ecosystem services provided by an urban lake. Lake Reserv Manage. 37:418–430. Integrating the perception of water quality in management efforts can be an effective way of developing and evaluating management plans targeted at preserving lake ecosystem benefits. We present a case study of Oswego Lake (OR), an urban lake that has been intensively managed for the past 20 yr to preserve valuable esthetic and recreational benefits. We combined the analysis of a long-term water quality dataset with survey data to assess whether management efforts over time successfully met the expectations of people using the lake. The synergistic impact of both in-lake and watershed management activities significantly reduced whole-lake nutrient concentrations; however, high external phosphorus loading from native soil sources and the surrounding urbanized watershed likely continued to contribute to episodes of cyanobacteria blooms during the summer and partially limited in-lake management efforts. Although there was no statistically significant change in mean summer water transparency over the 20 yr management period, more than 60% of the people that have access to the lake thought the water quality had improved since they started using the lake. The lake was also perceived as “suitable” for esthetic and recreational enjoyment by users. As with other lakes in highly developed urban watersheds, Oswego Lake requires ongoing interventions to maintain adequate water quality. Management challenges include coordination of multiple stakeholders and jurisdictions with sometimes conflicting goals and constituencies, maintaining a long-term monitoring program that can produce consistent high-quality data, and keeping in touch with user groups to ensure that lake water quality meets expectations.","PeriodicalId":18017,"journal":{"name":"Lake and Reservoir Management","volume":"37 1","pages":"418 - 430"},"PeriodicalIF":1.5,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47138270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Relative importance of recreational boat wakes on an inland lake. Lake Reserv Manage. 37:227–234. Wakes generated by recreational boats have the potential to erode the shoreline, damage infrastructure, or disrupt aquatic ecosystems. Therefore, boat wakes are an increasingly important focus of coastal management, particularly along vulnerable shorelines. This short communication quantifies the relative importance of recreational boat wake energy along the shoreline of an inland cottage lake in Northern Ontario, Canada. Measurements of recreational boat wakes at the end of one of the longest fetches for locally generated wind waves on the lake account for >61% of total wave energy. Based on this result, recreational wake energy likely is the primary source of wave activity along sections of the lake adjacent to the primary sailing lines but not aligned to the primary directions of wind wave energy. Recreational boat wakes may be a significant source of wave energy on other inland lakes.","PeriodicalId":18017,"journal":{"name":"Lake and Reservoir Management","volume":"37 1","pages":"227 - 234"},"PeriodicalIF":1.5,"publicationDate":"2021-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10402381.2021.1879325","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47958741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An experimental evaluation of the efficacy of imaging flow cytometry (FlowCam) for detecting invasive Dreissened and Corbiculid bivalve veligers. Lake Reserv Manage. 37:406–417. Zebra (Dreissena polymorpha) and quagga (D. bugensis) mussels, first introduced from central Asia into the Great Lakes of North America in the late 1980s, have crossed the continental divide and more recently spread across western North America. At the same time, several new technologies have been developed for the early detection of dreissenids, including the FlowCam, a digital imaging-in-flow instrument, intended to detect dreissenid planktonic larvae (veligers). However, the efficacy of this technology has rarely been tested. We experimentally evaluated the FlowCam’s ability to capture identifiable images of quagga mussel veligers under 2 different types of conditions: (i) deionized water, and (ii) Columbia River Basin water (CRBW), including natural sediment and native plankton. We further evaluated the FlowCam’s ability to distinguish between dreissenid veligers and corbiculid veligers (Asian clam, Corbicula fluminea). We interpret our results to indicate that the FlowCam can consistently detect dreissenid veligers across a range of veliger densities. Moreover, the presence of other plankton and detritus only slightly affected dreissenid detection by the FlowCam. However, the orientation of individual bivalve veligers as they were imaged by the FlowCam precluded specific identification of a substantial proportion (24.8%) of veligers as either dreissenid or corbiculid. We suggest that the FlowCam is an important detection tool best utilized as part of a multifaceted approach, including traditional microscopy and possibly environmental DNA.","PeriodicalId":18017,"journal":{"name":"Lake and Reservoir Management","volume":"37 1","pages":"406 - 417"},"PeriodicalIF":1.5,"publicationDate":"2021-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48506018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recreational angling gear is a high-risk pathway of dispersal for the invasive spiny water flea (Bythotrephes cederströmii). We measured the number of Bythotrephes individuals ensnared on trolled shallow angling lines (3 line materials), a trolled downrigger angling line, a trolled downrigger steel cable, a trolled simulated livewell, a trolled bait bucket, and stationary anchor ropes (3 rope materials) in 2 Minnesota (United States) lakes. The shallow angling lines and the downrigger angling line had the greatest mean ensnarement rates (number of Bythotrephes individuals ensnared/transect transit), followed by the downrigger cable and the livewell, followed by the bait bucket and the anchor ropes. Added together, the shallow angling lines (as a mean of the 3 line materials) and the downrigger angling line accounted for 87–88% of the mean total ensnarement rate. Among the shallow angling lines, monofilament and fluorocarbon lines had greater mean ensnarement rates than braided line but the distinction was only statistically significant in one of the 2 lakes. The ensnarement rate of all angling gear combined was positively related to the density of Bythotrephes in the water column at the time of study (ambient density). On the downrigger angling line (monofilament), instar-3 Bythotrephes were ensnared at a relative frequency disproportionately greater than ambient density would predict, while instar-1 Bythotrephes were ensnared at a relative frequency disproportionately less than ambient density would predict. Our results suggest that education and outreach messaging should include instructions on removing Bythotrephes from angling lines in addition to the reminder to drain all water.","PeriodicalId":18017,"journal":{"name":"Lake and Reservoir Management","volume":"37 1","pages":"391 - 405"},"PeriodicalIF":1.5,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43283261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seasonal patterns of methylmercury production, release, and degradation in profundal sediment of a hypereutrophic reservoir. Lake Reserv Manage. 37:360–377. Profundal lake sediment is an important site of toxic methylmercury (MeHg) production by anaerobic bacteria. This study tracked sediment MeHg cycling in hypereutrophic Hodges Reservoir, in the United States. Sediment-associated MeHg was most elevated in the early spring during moderately reduced conditions. In the late spring, MeHg and iron were released into hypolimnetic water during the progression from iron-reducing to sulfate-reducing conditions at the sediment–water interface. A decrease in porewater sulfate in the early summer indicated enhanced sulfate-reducing bacteria (SRB) activity and was associated with sediment buildup of MeHg, likely due to enhanced sorption to iron sulfides. Depletion of sulfate in the sediment during the fall corresponded with a substantial decrease in both sediment and water-column MeHg, suggesting that methanogenic conditions led to enhanced MeHg degradation. Shortly afterward, MeHg increased in the hypolimnion, indicating an upward shift in the zone of SRB methylation. Our study suggests 2 “hot moments” of MeHg entry into the water column, where it is susceptible to uptake into the pelagic food web: a spring window of mildly reduced conditions that promote MeHg release from sediment, and a fall window where MeHg is produced in the upper hypolimnion. These hot moments may potentially be managed to lower mercury bioaccumulation via redox enhancement of the profundal zone with approaches such as bottom water oxygenation, which began operation in Hodges Reservoir in 2020. However, the complexity of biogeochemical responses to such management perturbations in regard to MeHg cycling makes it difficult to predict the ultimate effect of oxygenation on mercury bioaccumulation.

Long-term monitoring data from freshwater lakes can be challenging to retrieve yet are valuable for assessing lakes at risk of saltwater intrusion. We demonstrate the use of an applied paleolimnological method to identify the response of a freshwater lake to seawater incursion and salinity-induced meromixis by examining the geochemistry of lake sediments deposited over the past century. Laytons Lake is located 1.5 km from the Bay of Fundy coastline, and experienced documented seawater incursion events in 1944 and 1949 leading to a period of extended meromixis (>40 yr). Our limnological measurements indicate that meromixis no longer exists at Laytons Lake, and hypolimnetic phosphorus (P) concentrations and conductivity values have declined since 1982. Meromictic conditions, the establishment of the chemocline, and high sedimentation rates collectively preserve a geochemical record of seawater incursion, which was identified as a short-duration, positive chloride (Cl-) excursion followed by the precipitation of iron sulfide (FeS2). A decline in Cl- concentration after the incursion events in the paleorecord may represent the deterioration of the chemocline, and the reestablishment of thermal stratification and mixing. We suspect that seawater incursions can have a multidecadal impact on aquatic systems, and that bulk geochemical analysis of paleolimnological records is a useful, low-cost tool that can provide a long-term perspective on the limnological consequences of such events. These long-term data can inform the assessment of aquatic systems at risk of saltwater incursion due to sea-level rise.","PeriodicalId":18017,"journal":{"name":"Lake and Reservoir Management","volume":"37 1","pages":"378 - 390"},"PeriodicalIF":1.5,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10402381.2021.1941446","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44883921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydrology of annual winter water level drawdown regimes in recreational lakes of Massachusetts, United States. Lake Reserv Manage. 37:339–359. Annual winter water level drawdown (WD) is a common lake management strategy to maintain recreational value by controlling nuisance macrophytes and preventing ice damage to shoreline infrastructure in lakes of the northeastern United States. The state of Massachusetts provides general guidelines for lake managers to implement and practice WDs. However, WD management reporting is not required and as such empirical water level records are scarce, making it difficult to assess guideline adherence and link these management actions to littoral habitat conditions. We monitored water levels bihourly in 18 lakes with ongoing WD regimes and 3 non-drawdown lakes over 3–4 yr. Our results show an interlake drawdown magnitude gradient of 0.07–2.66 m with intralake consistency across years. Corresponding WD magnitudes generated exposure of 1.3–37.6% for entire lakebeds and 9.2–71.1% for littoral zones. WD durations averaged 171 d and ranged widely from 5 to 246 d. Longer recession and refill phase durations and faster recession rates were moderately to strongly correlated with drawdown magnitudes. WDs were predominantly initiated prior to the state of Massachusetts 1 November starting guideline (83.1%) and refilled to summer reference levels after the recommended date of 1 April (70.6%). To minimize ecological impacts while still meeting recreational goals, WD performance guidelines may require a more fine-scale approach that integrates local hydrogeomorphic features and the presence of WD-sensitive littoral biotic assemblages. However, climate change model projections of warmer and wetter winters in the Northeast indicate increasing uncertainty for WD as an effective and worthwhile macrophyte control tool.","PeriodicalId":18017,"journal":{"name":"Lake and Reservoir Management","volume":"37 1","pages":"339 - 359"},"PeriodicalIF":1.5,"publicationDate":"2021-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10402381.2021.1927268","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41701011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Estimates of internal loading of phosphorus in a western US reservoir using 3 methods. Lake Reserv Manage. 37:261–274. We used 3 methods to estimate internal loading of total and dissolved phosphorus (TP/DP) in 2 years in a stratified eutrophic western US reservoir with high internal loading of phosphorus. We calculated the internal load from (i) net increases of TP/DP from reservoir water column samples, (ii) gross TP mass balances, and (iii) gross TP/DP loading estimated from laboratory-incubated sediment cores and the anoxic reservoir area. We also present a cost comparison and spreadsheet to allow managers to estimate costs for each method. The highest internal loads were estimated in 2015 from the net in situ samples (999 mg/m2/yr) and the gross annual mass balance (850 mg/m2/yr). Gross estimates from sediment cores were 1.2× higher in 2015 than in 2014 due to differences in anoxic area resulting from a drought and record reservoir drawdown. Costs were highest for the mass balance method and lowest for the sediment core method. Given the small monetary difference between the sediment core and in situ methods, we suggest managers obtain in situ data to estimate internal loading because this yields a net estimate most reflective of whole-lake dynamics. Our data provide an important benchmark of internal loading in a human-made reservoir given the general paucity of such estimates in this large geographic region.","PeriodicalId":18017,"journal":{"name":"Lake and Reservoir Management","volume":"37 1","pages":"261 - 274"},"PeriodicalIF":1.5,"publicationDate":"2021-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10402381.2021.1923590","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45124751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multipurpose reservoirs can be used to manage habitat for shorebirds during migration, an energetically costly event that may influence demographics and population numbers. This is particularly true for shorebirds that migrate through the interior of the United States, which has lost much of its wetland habitat. Shorebirds use aquatic systems during stopover periods throughout migration to rest and refuel. Understanding the factors that influence the probability of a shorebird remaining at a stopover area can inform decisions regarding reservoir management. We examined the influence of habitat and environmental covariates and body condition on the daily local residency probability of migrant least sandpipers (Calidris minutilla) at Saylorville Lake, a reservoir in central Iowa. We monitored 189 least sandpipers in fall 2016, 2017, 2019, and 2020 using radiotelemetry. Using a nest survival model, our most competitive model included significant negative effects of water level (β = −8.35, 85% CI = −11.18, −5.52) and body condition (β = −4.91, 85% CI = −6.82, −3.01) on residency probability. We calculated a mean daily local residency probability of 0.78 (95% CI 0.56, 1.00) and used this value to calculate a minimum stopover duration of 3.96 d (95% CI = 3.45, 4.46). Our findings indicate that the timing of water level management at Saylorville Lake can impact the residency probability of the least sandpiper. Drawing down water levels just prior to fall migration and maintaining water levels at or below the conservation pool level (254.8 m) can provide habitat for this species and likely other shorebirds.","PeriodicalId":18017,"journal":{"name":"Lake and Reservoir Management","volume":"37 1","pages":"300 - 312"},"PeriodicalIF":1.5,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10402381.2021.1920071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44033662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
