We created six new tree‐ring chronologies in northern Utah, which were used with preexisting chronologies from Utah and western Wyoming to reconstruct mean annual flow for the Logan River, the largest tributary of the regionally important Bear River. Two reconstruction models were developed, a “Local” model that incorporated two Rocky Mountain juniper chronologies located within the basin, and a “Regional” model that also included limber pine and pinyon pine chronologies from a larger area. The Local model explained 48.2% of the variability in the instrumental record and the juniper chronologies better captured streamflow variability than Douglas‐fir collected within the Logan …

Dendrochronology In Northern Utah: Modeling Sensitivity And Reconstructing Logan River Flows, Eric B. Allen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The population centers in northern Utah are highly dependent upon snowpack for drinking water, irrigation, and hydropower. When the snowpack melts in the spring and early summer, it feeds streams draining the Wasatch, Bear River, and Uinta Mountains. The rivers are diverted and dammed to deliver water to the greater Salt Lake metropolitan area. In order to properly allocate this water, managers need to know how much water normally flows in the rivers and the frequency and magnitude of wet and dry periods to expect. However, climate patterns in the region are not well understood and records of streamflows are …
