Live US lake and reservoir water levels from USGS, USACE, CDEC, USBR and TWDB gauges.
Reads live US lake and reservoir water levels from government gauges, letting an assistant look up current elevation, history and comparisons for 44 lakes.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.theluckystrike%2Flake-level-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Live US lake and reservoir water levels for AI assistants, read at call time from USGS, USACE, CDEC, Reclamation and TWDB gauges.
This is a Model Context Protocol (MCP) server. It covers 44 lakes in 12 states, including Lake Mead, Lake Powell, Lake Travis, Shasta, Oroville, Folsom, Lake Lanier, Lake Texoma and Kentucky Lake. It needs no API key.
Every result has structured JSON, a one-paragraph summary, as_of, source (the agency URL) and more (the lake page on lakelevelnow.com).
Paste this URL. No token, no sign-up.
Or run it locally over stdio:
Add to claude_desktop_config.json:
Add to ~/.cursor/mcp.json:
Add to .vscode/mcp.json:
Node 20 or newer is needed for the local stdio version.
All public and keyless. Full list with fetch dates in DATA_SOURCES.md.
Upstream answers are cached for 15 minutes (current level) or 1 hour (history) to respect the agencies' services.
Charts, boat ramp context and the paid Lake Level Almanac (decades of daily record and day-of-year normals per lake) are on lakelevelnow.com. The almanac covers 19 of these lakes: lakelevelnow.com/almanac.
Part of the Zovo MCP collection: https://mcp.zovo.one
src/lakes.data.ts is generated from the lakelevelnow.com data by scripts/build-lakes.mjs.
MIT
Each one is free, needs no API key and has a hosted URL you can paste into Claude or ChatGPT.
The paid back-office collection (invoices, VAT, PDFs, spreadsheets) is at https://mcp.zovo.one

Search US lakes and reservoirs
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.
querystateGet current lake level
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.
lakerequiredGet lake level history
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.
dayslakerequiredstepCompare lake levels
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.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
