The City of Fort Collins is requesting access for water quality and vegetation sampling along the North Fork of the Poudre River to benefit the City's Halligan Reservoir Water Supply Project. The City has contracted with Jacobs to conduct data collection beginning this field season and extending on an annual basis for the next 10+ years. Jacobs staff would like to conduct the initial field work the week of August 24-August 28th.

Data collection includes vegetative sampling which would involve point intercept transects and plots to characterize the vegetative community (composition, cover, structure, etc.). A t-post would be used to mark a reference starting point of our plots so Jacobs can survey the same place each year for the sake of interannual comparison. The longitudinal profile will involve a 1000-2000’ reach of the stream. Jacobs will survey the thalweg elevation and document conditions of the stream including bank stability, substrate pebble counts, presence of aquatic habitat structure (riffle-pool, large eddies, undercut banks, large woody debris/jams, etc.), and bank stability. The objective is to fully describe a small segment of a stream and its overbank riparian habitat to provide a reference reach and an affected reach of the North Fork.

In addition, Jacobs would like to install groundwater monitoring wells. Staff recognize that this might require additional permits or easements.The shallow groundwater monitoring well would be installed by hand (hand auger/shovel) and would be about 4-6 feet deep – pvc or steel pipe. The well will be installed with a secure cap and will include automated data logger (probably a hobo with barometric equalizer) to track changes in floodplain groundwater elevations – to eventually be correlated with the discharge and stage readings at the future stream gauge. The well(s) can be installed as a flush mount or with a riser (Jacobs staff would prefer to use a riser so it will be easier to find in future years). Jacobs will remove and backfill the well when/if it is no longer needed (probably about 10 years of monitoring).
