The Bailiwick of Ennerdale Est 1251 - Hon. George Mentz JD MBA CWM

 

 

⚖️ Conservative Foreshore Acreage – Bailiwick of Ennerdale - Ennerdale one of the very few self-contained inland maritime jurisdictions in the British Isles.

Component Length / Area Conservative Average Foreshore Width (each side) Approx. Foreshore Acres Notes
River Liza 10 miles (55 000 ft) 15 ft 38 acres Narrower upland channel; includes both banks
Tributary becks 5 miles (26 000 ft) 10 ft 12 acres Small streams with steep banks
Ennerdale Water (lake) 2.5 mi long × 0.75 mi wide ≈ 525 surface acres 25 ft average foreshore belt 110 acres Conservative band around 6-mile shoreline
Total foreshore ownership ≈ 160 acres (±10 %) Does not count full lakebed

Summary

Conservatively, the Lord of Ennerdale would own about 150 – 170 acres of foreshore land, encompassing:

  • Both sides of the River Liza and its tributaries

  • The entire gravel, rock, and sand margin of Ennerdale Water

That’s the minimum credible figure for legal or valuation purposes — wide enough to reflect ordinary high- and low-water marks, yet excluding broader flood meadows or wetland shelves.

 

Speculation Values

🌊 Total Water and Foreshore Area Including Ennerdale Water

1. Facts about Ennerdale Water

  • Length: ≈ 2.5 miles (4 km)

  • Maximum width: ≈ 0.75 miles (1.2 km)

  • Surface area: ≈ 0.82 square miles = 525 acres (modern Ordnance Survey and Environment Agency figures)


2. Components of Foreshore Around the Lake

“Foreshore” (in a lake context) = land between ordinary high and low water marks, i.e. the fluctuating zone of exposed beach or gravel.
Typical average width of lake foreshore: 20–60 ft depending on slope and drawdown.

Formula for circumference area:

Foreshore acres=(Perimeter ft)×(Average width ft)÷43,560\text{Foreshore acres} = (\text{Perimeter ft}) × (\text{Average width ft}) ÷ 43,560

Approximate shoreline perimeter of Ennerdale Water ≈ 6 miles = 31,680 ft × 6 = 190,000 ft.


3. Scenarios for Lake Foreshore

Average Foreshore Width Foreshore Area Comment
20 ft (190,000×20)/43,560 = 87 acres Steep rocky shore assumption
40 ft 175 acres Moderate gradient – realistic
60 ft 262 acres Includes wider gravel and flood margins near inflow/outflow

A mid-range ≈ 175 acres of lake foreshore is a fair, defensible estimate.


4. Combine with River Foreshore

Feature Estimated Foreshore Acres
River Liza + becks ~ 85 acres
Ennerdale Water (lakebed foreshore only) ~ 175 acres
Subtotal – Foreshore only ≈ 260 acres
Plus full lakebed (below low-water) + 525 acres
Total water + foreshore under ownership ≈ 785 acres

Summary

Category Area (acres) Ownership Implication
River & streams (foreshore) ~ 80–100 Riparian soil + fishing + abstraction rights
Lake (foreshore) ~ 150–200 Gravel beach, sand, and mooring rights
Lake bed (below low water) ~ 525 Exclusive subaqueous title
Total aquatic domain ≈ 700–800 acres Within the Fee-Simple Liberty of Ennerdale

5. Legal and Heritage Note

Because Ennerdale’s lake, inflow, and outflow are wholly enclosed within the historical bailiwick, the Lord of Ennerdale (or successor titleholder) effectively holds continuous dominion over an ~800-acre hydrological estate — a combination of:

  • exclusive foreshore control,

  • bed and subsoil ownership,

  • and historic fisheries and mineral rights.

This makes Ennerdale one of the very few self-contained inland maritime jurisdictions in the British Isles.

 

🌊 Foreshore Acreage Estimate – Ennerdale Rivers & Streams

1. Known Facts

  • Main river: The River Liza, roughly 10.5 miles (55,440 ft) long inside the Liberty.

  • Foreshore: Exists on both banks, bounded by the ordinary high- and low-water marks of the stream or river.

  • Width: Varies widely with channel size, but we can use realistic average widths to model a range.


2. Step-by-Step Calculation

🧮 Formula

Acreage=(Length in ft)×(Average Foreshore Width)43,560\text{Acreage} = \frac{(\text{Length in ft}) \times (\text{Average Foreshore Width})}{43,560}

Multiply by 2 (for both sides of the river).


3. Scenarios

Average Width (each side) Total Width (both sides) Acreage = 55,440 ft × width ÷ 43,560 Comment
10 ft 20 ft 25.4 acres Very narrow stream margin
20 ft 40 ft 50.7 acres Typical upland river course
30 ft 60 ft 76.1 acres Average Ennerdale reach (mid-valley)
40 ft 80 ft 101.5 acres Broad flood-meadow sections
50 ft 100 ft 126.9 acres Includes shallow gravel flats near Ennerdale Water outflow

4. Tributary Allowance

If we include ~5 miles (26,400 ft) of additional becks and burns with average 15-ft combined width:

26,400×15÷43,560≈9.1acres26,400 × 15 ÷ 43,560 ≈ 9.1 acres


5. Total Foreshore Estimate

Component Estimated Acreage
River Liza (average 30 ft/side) ≈ 76 acres
Tributary becks (minor streams) ≈ 9 acres
Total riparian & foreshore area ≈ 85 acres

Result

Approximate foreshore area within the Bailiwick of Ennerdale:
80 – 100 acres (depending on channel breadth and floodplain definition).


6. Context for Valuation

Those ~85 acres represent:

  • Permanent riparian soil ownership (bed + banks + foreshore),

  • Valuable fishery and water rights,

  • Control over hydrological access, dredging, abstraction, and moorings,
    making it one of the few English liberties with a continuous private river system entirely within its grant.
