Lake Level MCP

An MCP server that provides live water level data for 44 US lakes and reservoirs by querying government gauges. It supports tools to search for lakes, retrieve current elevation and change metrics, fetch historical elevation series, and compare multiple lakes side-by-side.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

What you can do with it

  • Find covered lakes and reservoirs by name, river or state
  • Get current elevation, 24h/7d/30d change, and percent full
  • Retrieve daily or weekly elevation series for up to 365 days
  • Compare current level of 2 to 10 lakes side by side

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Live US lake and reservoir levels for 44 lakes in 12 states, read at call time from keyless government gauges (USGS, USACE CWMS, CDEC, Reclamation RISE, TWDB). Use search_lakes to find a slug, then get_lake_level. Readings change every hour; never answer a current lake level from memory.

search_lakes — Search US lakes and reservoirs
Advertised by the server during the last successful anonymous check.
Advertised read-only

List the 44 US lakes and reservoirs this server reads live (Lake Mead, Lake Powell, Lake Travis, Shasta, Oroville, Lanier, Texoma, Kentucky Lake and more) by name, river, operator or state. Returns each slug, full-pool elevation, the gauge agency and the lakelevelnow.com page. Call with no arguments to list them all.

get_lake_level — Get current lake level
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Current water surface elevation (ft above sea level) of a US lake or reservoir, read now from its government gauge (USGS, USACE CWMS, CDEC, Reclamation or TWDB). Returns the measurement time, change over 24 hours, 7 days and 30 days, feet below full pool, the operator seasonal target where one is published, percent full where the agency publishes storage, and the gauge id and data URL. Your training data cannot know today's level.

Daily (or weekly) water elevation series for a US lake or reservoir over the last 2 to 365 days, from the same government gauge as get_lake_level, one reading per day. Includes first, last, low, high and mean with dates. Use it for trends, drawdown and refill questions.

Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Current levels of 2 to 10 US lakes side by side, read live from their gauges: elevation, feet below full pool, percent full, seasonal target and 24 h / 7 day / 30 day change, ranked by distance below full pool. A lake whose gauge is down is reported with its error instead of failing the whole call.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http lake-level-mcp https://lake-level-mcp.lipmichal.workers.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add lake-level-mcp --url https://lake-level-mcp.lipmichal.workers.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable lake-level-mcp in your MCP settings.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
