Maine Networks Section Spring Update

Release Date:

The Maine SW/GW (Surface-Water/Groundwater) Networks Section has been busy this spring- confirming our equipment is working properly after the winter, making high flow measurements to confirm our stage-discharge relationships and preparing for upcoming summer projects. 

Hydrologic technician Jeremiah Pomerleau at our GW monitoring station at Middle Dam, Maine. Jeremiah used the UTV to access the remote site and confirm reported water levels were accurate. This data is useful for monitoring spring recharge and tracking potential drought conditions. Check out the latest data from the site here.

Andy Cloutier visited station 01069500 Mousam River near West Kennebunk, Maine recently to make a low flow measurement. This wasn’t any low flow measurement, but the lowest ever made in the 57 year period the USGS has been collecting data there! In the hydrograph below, there is a sudden drop in flow due to regulation upstream. Andy confirmed our stage-discharge rating was accurate (see the red dots?) and got the honor of having the lowest measured flow at the site.
