“…Several studies have measured sediment P release rates in lakes and reservoirs across North America and found fluxes ranging between 1 and 50 mg m −2 d −1 under aerobic and anaerobic conditions (e.g., Holdren and Armstrong, 1980; Moore and Reddy, 1994; Riley and Prepas, 1984). The range in mean P release rates under aerobic and anaerobic conditions in local reservoirs has been between approximately zero and 6 mg m −2 d −1 (Haggard et al, 2005, 2012; Sen et al, 2006). Our measured P release rates at Lake Tenkiller were within the range of that observed locally under aerobic conditions but double the maximum average under anaerobic conditions.…”

Core Ideas Sediment P release needs to be measured in lakes and reservoirs that are eutrophic. Sediment P release data is essential for calibrating lake and reservoir models used in a TMDL. Sediment P release at Lake Tenkiller was very high relative to that predicted by the model. Sediment P release was also very high relative to that observed in regional reservoirs. Internal P sources need to be addressed in watershed management strategies. Watershed management for lakes and reservoirs largely focuses on external sources, but internal sources, such as sediment P release, can be important. This study quantified sediment P release in Lake Tenkiller, Oklahoma, in summer 2016. Eight intact sediment–water cores were collected from the riverine and transition zone and then incubated at 22°C for 8 d under aerobic and anaerobic conditions. Phosphorus mass in the overlying water of all cores increased with time, and the rate of increase was significantly greater under anaerobic conditions. Sediment P release was reflective of eutrophic and hypereutrophic conditions, measuring up to 15.2 mg m−2 d−1. Sediment P fluxes were four to five times greater than the net flux predicted by the model of Lake Tenkiller, suggesting that internal P sources need to be considered in the total maximum daily load process.

“…Sediment P release is an important consideration in water quality modeling and total maximum daily load (TMDL) development for lakes and reservoirs. Sediment P release is commonly used as a calibration parameter in lake modeling, which can potentially over‐ or underestimate the importance of the internal P source (Haggard et al, 2012).…”

“…When external P loads are reduced in shallow lakes, internal P release can be a key factor contributing to eutrophication, and thus may interfere with lake restoration efforts (Nürnberg et al, 1986;Loh et al, 2013;Powers et al, 2014). Sediment, a critical source and reservoir of nutrients in lake ecosystems, can play a very important role in the process of eutrophication (Haggard et al, 2012;Kraal et al, 2015). The diffusion of P at the watersediment interface is dependent not only on P absorption-desorption from sediment, but also on a number of physical and chemical parameters (Nürnberg et al, 1986;Ishii et al, 2010;Loh et al, 2013;Wang and Liang, 2014).…”

Communicated by Gerald MatisoffDongting Lake is a typical shallow lake in the lower Yangtze region and is the second largest freshwater lake in China. The distribution, speciation, and sediment release characteristics of phosphorus (P) were investigated by analyzing sediment and water samples collected during high and low flow periods. The average concentration (range) of total phosphorus (TP) in the water was 0.05 mg L −1 (0.02~0.09 mg L −1), while the value in sediment was 703 mg kg −1 (466~869 mg kg). The concentrations of TP and different P forms decreased as depth increased. Inorganic phosphorus was the dominant form of P, accounting for 72% of TP. The bioavailable P was a relatively large portion of TP, indicating a high risk of P release to overlying water. The Langmuir equation can well describe the P isotherm adsorption characteristics in sediment. The amount of P desorption from sediment tended to increase with increasing concentrations of adsorbed P.

Bu araştırma iç sularda, kafeslerde gökkuşağı alabalığı yetiştiriciliğinin yapıldığı baraj göllerimizden biri olan Almus Baraj Gölü'nde; kafes işletmelerinin yoğun dağılım gösterdiği alanı temsilen seçilen iki kafes istasyonu (I-II) ile hakim akıntı yönü dışında sırasıyla 250 m ve 500 m uzakta belirlenen iki kontrol istasyonunda (III-IV) 2015 yılının Nisan ve Ekim aylarında yürütülmüştür. Araştırma kapsamında baraj gölünde sedimentten suya olan fosfor salınım düzeyi tahmin edilmiş ve salınımda etkili faktörler tartışılmıştır. Almus Baraj Gölü'nde fosfor salınım düzeyleri oldukça düşük tahmin edilmiş; en düşük fosfor salınım değeri kafes istasyonlarına 500 m uzakta seçilen kontrol istasyonunda (14.58 μgP m-2 gün-1) nisan ayında, en yüksek değer ise aynı ayda I No.lu kafes istasyonunda (31.73 μgP m-2 gün-1) belirlenmiştir. Sedimentten suya fosfor salınımının engellenmesinde etkili fosfor fraksiyonları sırasıyla organik bağlı fosfor (Org≈P; %24) > kalsiyuma bağlı fosfor (Ca≈P; %22) >demir+alüminyuma bağlı fosfor (Fe+Al≈P; %18) >karbonata bağlı fosfor (CO 3 ≈P; %13) olarak belirlenmiştir. Ayrıca sediment gözenek suyu TFe/TFO oranına ilişkin değerin yüksek saptanması ve sedimentin killi-siltli tanecik yapısı salınımda etkili unsurlar olarak belirlenmiştir.
