This project tested and evaluated methods that could be used to estimate the distribution and biomass of metaphyton in the nearshore and washing up off of three beaches where metaphyton had been observed in the past: Round Hill Pines Beach in NV and El Dorado and Regan Beaches in CA. Observations through time for Lake Tahoe suggest metaphyton is heaviest in mid-summer to early fall. Monitoring was conducted during two occasions between July and September 2015, as it was believed this would capture the period of peak metaphyton abundance. One transect extending perpendicular to the shore was established at each of the study sites. Monitoring included biomass sampling and photo documentation.

| 12/05/2018 2:44 PM | Meredith Gosejohan | Findings: - Of the metaphyton monitoring methods investigated, metaphyton percent cover estimated in the field, metaphyton percent cover estimated from photos and Ash Free Dry Weight (AFDW) appeared to be the best choices for Lake Tahoe metaphyton monitoring. - Percent coverage estimated from photos taken of metaphyton in quadrats is a potentially useful method to assess levels of metaphyton. - AFDW appeared to be a better method than dry weight or chlorophyll a for estimation of metaphyton biomass. - Monitoring in this pilot study showed that metaphyton was present offshore during all three summers during 2015-2017 at Regan and El Dorado beaches; however metaphyton deposition onshore did not appear to occur in all three years. - Monitoring results and field observations made in this study suggest nearshore slope or gradient and lake level may play a role in the degree to which metaphyton accumulates along the shoreline and is deposited on the beach. |
