At a Glance

This schematic diagram illustrates the Logan River Observatory (LRO) monitoring network in northern Utah, which is designed to track the hydrological and meteorological dynamics of the Logan River watershed. Blue markers represent streamflow monitoring sites, while green markers denote meteorological stations. Arrows indicate the direction of water flow from headwater streams through the mainstem of the Logan River and into Cutler Reservoir. The flow of water begins in the upper watershed at tributaries such as Temple Fork, Spawn Creek, and Right Fork, with additional inputs from Franklin Basin, Tony Grove Lake Inlet, and Tony Grove Lake Outlet. These headwaters converge at various junctions along the main channel. For instance, Temple Fork and Right Fork flow into the Upper Logan River, while water from Tony Grove flows into the Logan River above Red Banks. The river continues downstream through a sequence of monitoring points including Red Banks, Logan River below Red Banks, and Spring Hollow. As the river progresses through the lower watershed, it passes through the Logan River at Twin Bridges, at Main Street, at Mendon Road, at the Golf Course, and at Benson Marina. Finally, the river discharges into Cutler Reservoir. A separate monitoring site also captures conditions directly at the outlet of the reservoir. This network provides comprehensive spatial and temporal data to support water resources research, integrating streamflow observations with meteorological data to enhance understanding of watershed processes and climate impacts.

Supporting Data

The Logan River Observatory collects and supports additional datasets that are available to the public:

2023 AggieAir Logan River Data

Logan River Aerial Photo

On May 24, the AggieAir Service Center completed 5 UAV flights during peak flows on the Logan River to collect high-resolution visual and thermal imagery to assess the extent of flooding. Products include DSM, Reflectance Mosaics, and a Digital Number Mosaic. 

Please contact Bethany Neilson for datasets. 

2020 Logan River Watershed Lidar Elevation Data

Logan River LiDAR

During 2020 Utah State University, Utah Water Research Laboratory acquired ~216 square miles of 8 points per square meter LiDAR of the Logan River Watershed in Northern Utah. Products include 0.5 meter resolution derived bare earth DTM and first return DSM rasters.
