I have published a new online application to improve public access to streamflow reconstruction data. You can find it at www.paleoflow.org. The site allows users to visualize reconstructed flows over multiple centuries and interact with the series by zooming in on specific periods. It also allows users to find extreme flows below/above a threshold, easily compare any two historical periods, and visualize the goodness of fit, relative to observed flows.
The site currently includes 3 monthly reconstructions and many annual reconstructions (with more being added constantly).
