  <dc:description>&lt;h3 class="c-article__sub-heading" data-test="abstract-sub-heading"&gt;Objective&lt;/h3&gt;&lt;p&gt;We described source and phosphorus (P) retention potential of soft, fine-grained, streambed sediment and associated phosphorus (sed-P) during summer low-flow conditions. Combining in-channel, sed-P storage with relative age provided context on relevance to western Lake Erie Basin management goals.&lt;/p&gt;&lt;h3 class="c-article__sub-heading" data-test="abstract-sub-heading"&gt;Methods&lt;/h3&gt;&lt;p&gt;In 2019, rapid geomorphic assessment (30 reaches) compared streambed-sediment storage (S) to streambank erosion (E), providing annual sediment budgets (S:E). Streambed sediment (13 reaches) was fingerprinted and analyzed for sed-P. The P saturation ratio (PSR; four reaches) quantified potential sorption/desorption of dissolved P (DP) between the water column and streambed sediment. Analyses were supplemented with data from 2017 and 2021. The ratio of two fallout radionuclides, beryllium-7 (54-day half-life) and excess lead-210 (22.3&amp;nbsp;years), apportioned “new” sediment based on time since rainfall contact.&lt;/p&gt;&lt;h3 class="c-article__sub-heading" data-test="abstract-sub-heading"&gt;Results&lt;/h3&gt;&lt;p&gt;Streambed sediment was mostly streambank (54–96%) for contributing areas &amp;gt; 2.7 km&lt;sup&gt;2&lt;/sup&gt;; for upstream reaches, a larger percentage was apportioned as upland (cropland, pasture, forest, and road), with &amp;lt; 30% streambank. Streambank erosion correlated with contributing area; however, soil type (ecoregion), stream characteristics, and land use combined to drive streambed-sediment storage. Individual-reach S:E (accumulation of 0.01–35&amp;nbsp;years of streambank erosion) differentiated erosional and depositional in-channel environments. Most reaches indicated that 17–57% of sediment had recent contact with rainfall. Streambed-sediment PSR indicated a low potential for further sorption of DP from the water column; one reach was a P source when sampled.&lt;/p&gt;&lt;h3 class="c-article__sub-heading" data-test="abstract-sub-heading"&gt;Conclusion&lt;/h3&gt;&lt;p&gt;Sed-P was higher in streambed sediment than in source samples, which varied by land use and ecoregion. This indicates homogenization resulting from in-stream sorption of DP during sediment transport that occurs over multiple events.&lt;/p&gt;</dc:description>
