Fishing in County Durham, United Kingdom

What this local map set contains

The County Durham directory currently covers 5 lakes or reservoirs. No chart in this set currently has measured bathymetry; 5 charts are clearly labeled as modeled. Recorded maximum depths range from 6 to 121 ft, with a median of 62 ft. Those figures describe each chart's deepest recorded or modeled point, not a safe navigation depth.

Species records are attached to 5 of 5 waters. The most frequently cataloged targets are Brown Trout (5), European Perch (5), Northern Pike (5) and Arctic Char (4). These are coverage counts, not abundance estimates or catch forecasts; open the individual map to see the evidence and seasonal context attached to that water.

Three useful maps to compare first

1. Balderhead Reservoir: 121 ft maximum; modeled contours; 4 cataloged target species.
2. Grassholme Reservoir: 95 ft maximum; modeled contours; 4 cataloged target species.
3. Derwent Reservoir: 62 ft maximum; modeled contours; 4 cataloged target species.

Start with a survey-backed chart when exact contour shape matters most. Use a modeled chart as broad planning context, then verify depths on the water. Comparing the three examples above also shows whether this area offers one dominant basin type or genuinely different shallow, deep, lake and river options. Access is separate from map coverage: confirm launches, shore rights, closures and posted rules before making the trip.
