Why We Don't Publish GPS Coordinates (and What We Publish Instead)

The angler-multiplier problem

The math of small-stream wild trout fisheries is unforgiving. A productive wild-brookie reach -- the kind found in the headwaters of ANF (Allegheny National Forest) tributaries, in select WNY State Land streams, in the upper Cuyahoga feeders -- supports a population of perhaps a few hundred fish per mile. The biomass is small. The fish are slow-growing. The population recruitment is limited by spawning-habitat availability + thermal refuge availability.

When a fishing publication publishes the precise location of one of these reaches, the consequence is predictable: anglers find it, fish it, and the productive population declines. The fish themselves may survive catch-and-release fishing fine. But the cumulative angler pressure -- wading the spawning gravel, walking the banks, the simple physical disturbance -- changes the fishery within weeks of becoming "known."

This is not an academic concern. The peer-reviewed literature on small-stream wild trout fisheries (notably Letcher et al. 2015 on brook trout recruitment, Petty et al. 2014 on Appalachian brookie metapopulations) documents the rapid response of small-stream fish populations to localized angler pressure. The Eastern Brook Trout Joint Venture's conservation guidance specifically counsels against publishing specific small-stream access points for this reason.

The level of detail SHA publishes

SHA's conservation discipline draws a line between three categories of fishery guidance:

Category 1: Public-knowledge big water (specific is fine)

Large rivers, dam-controlled tailwaters, and publicly-known steelhead fisheries are public-information water. The Salmon River below the Altmar barrier is one of the most-fished steelhead waters in North America; publishing specific access points + USGS gauge readings + seasonal context does not appreciably change angler pressure. The fishery is already known, the access is publicly designated, and the additional information helps anglers fish safely and effectively. Specific examples in the SHA catalog:

• Salmon River, NY (Pulaski) -- specific access points + Lighthouse Hill Dam release info + regulations
• Cattaraugus Creek, NY -- gorge stretches identified by USGS gauge + Springville Dam tailwater
• Cuyahoga River, OH (Independence) -- gauge + flow + lower-river access
• Elk Creek, PA -- I-90 bridge + Girard Road + Manchester Access Area

Category 2: Regional wild-trout guidance (general only)

For wild brook trout streams and Class A wild trout reaches, SHA publishes regional-level guidance: "ANF tributaries hold wild brook trout," "WNY State Land includes designated Wild Trout Streams," "the Wiscoy is a Class A," but not specific access points or pool locations. The level of detail allows anglers to research the topic, contact the relevant agency (PA DCNR, NYSDEC, ODNR), and find water on their own -- which is, not coincidentally, the way wild-trout angling has been done for the last century.

Category 3: Truly fragile fisheries (no publication at all)

Some fisheries do not appear in SHA content at all -- not because they are unknown to the editor, but because publication at any level of detail would impose unacceptable angler-multiplier risk. The criteria: small population, slow recruitment, easy access from a major metropolitan area, and limited resilience to even modest angler pressure increases. These fisheries get nothing -- not the river name, not the regional reference, not a hint.

The Eastern Brook Trout Joint Venture ethic

The Eastern Brook Trout Joint Venture (EBTJV) is a multi-state coalition focused on brook trout conservation across the eastern United States. Its conservation guidance includes specific recommendations on angler-information practices for sensitive small-stream populations. SHA's editorial position aligns with the EBTJV ethic on this point.

The argument from the EBTJV side is straightforward: brook trout conservation depends on protecting the remaining strongholds, and "stronghold" includes both habitat and social-pressure-protection. Publishing GPS coordinates for one of those strongholds undermines the conservation work, even with the best of intentions.

The Trout Unlimited position

Trout Unlimited's national policy similarly counsels against publishing specific small-stream access information for wild and native trout fisheries. The TU Eastern Brook Trout Initiative explicitly recommends "general regional guidance, not specific access points" for sensitive populations. The TU pillar on SHA covers the broader TU work.

What anglers can do

For anglers interested in fishing wild and native trout reaches:

1. Join your local TU chapter. Chapters meet, share information among members, and organize on-water outings to appropriate water. The chapter-level network distributes information without publishing it.
2. Contact the relevant agency. PA DCNR, NY DEC, and ODNR all publish stream classifications and general access information. The agencies maintain access registries that are publicly available.
3. Read the public fly shop reports. Local fly shops near productive water often publish general fishing reports that hint at conditions without giving specific access points.
4. Walk water. The traditional approach -- look at maps, identify candidate reaches, walk water, find fish -- still works.

What we publish on bigger water

For the public-knowledge big-water fisheries in the SHA scope, the per-river pages publish:

• Live USGS gauge readings (every 15 minutes)
• Specific access points and parking locations
• State-agency stocking schedules + per-river fish counts
• Guide directories with proper licensing
• Featured business listings (fly shops, lodging, restaurants)
• Regulatory framework + permit requirements

This level of detail is appropriate for the fisheries that can absorb it -- and avoiding it for the fisheries that can't.

Honest gaps

• The line between Category 1 (public-knowledge big water) and Category 2 (regional wild-trout guidance) is sometimes fuzzy. SHA's editor errs toward Category 2 when uncertain.
• Some readers may find Category 2 frustrating -- they want specific access points and SHA isn't publishing them. The frustration is acknowledged; the editorial position stands.
• This position will not be popular with everyone. It is, however, the position the EBTJV + TU + most state agencies recommend.
