Residents in the Esopus valley objected to the dislocation the proposed reservoir would require, forcing out the population of seven hamlets and relocating the Ulster and Delaware. They also noted that both reservoirs would be outmoded in a decade, requiring the construction of more reservoirs, and suggested the city look further north, to the Adirondacks. They feared the dam would fail, and called the project the "Esopus folly".

The state's water supply commission ruled in the city's favor, and once the city began acquiring land most local objections faded because local lawyers, well versed in the tangled history of land claims on the former Hardenburgh Patent, were able to negotiate prices highly favorable to local landowners.

 as well. Because of that species' preference for later spawning dates in the fall, trout season along the Esopus extends until November 30, a month and a half later than most other streams in the state.

The Esopus is the only stream in the county with no minimum size restriction; up to five may be taken per day. Most fish taken are thus less than 12 inches (30.5 cm) in length, but in 1923 a brown trout was taken at Chimney Hole just above the reservoir that weighed 19 pounds (8.6183 kg). It was a state record that stood for three decades.
Anglers subdivide the upper Esopus into four sections: the small Esopus, from Winnisook Lake to Big Indian, and the three sections of the big Esopus. These are from Big Indian to the Portal, from the Portal to Phoenicia, and from Phoenicia to the reservoir.

. After lengthy litigation the city was eventually required to get a state permit for the discharges. Environmental groups have said the problems would be solved if the Schoharie, like all the other city reservoirs, had a multi-level discharge structure, allowing water to be taken from the less turbid surface as well as the cooler depths.

Boater and tuber user groups depend on releases from the Portal, which can add up to 900 cuft/s to the creek's flow, to make those activities possible.
