This not only effects those seeking info for safe recreational boating but more importantly info to issue flood warnings and evacuations and info to monitor climate change. USGS has this information on closings by state interactive maps and listings. Read on:

“The following streamgages have been or will soon be discontinued due to sequestration, or because of other funding reductions. If you have questions about specific streamgages, please contact the individual identified for each State. If you have questions about the US Geological Survey National Streamflow Information Program in general please contact Mike Norris (603-226-7847; mnorris@usgs.gov) or Robert Mason (703-648-5305; rrmason@usgs.gov).

Sequestration of USGS funds in mid-FY13 is requiring the USGS to discontinue a number of streamgages. Streamgages affected by sequestration are shown below as stars.
Several state and local agencies have provided funding to temporarily continue some streamgages (yellow stars) through September 30, 2013. Funding has not been secured for some streamgages (red stars) and we expect to have to discontinue them shortly. The remaining streamgages (black stars) either have been or will soon be discontinued.
When sequestration was implemented In March, the number of streamgages to be discontinued was initially calculated at 375 based on across the board cuts, but several factors have reduced this number. USGS has been able to take some of the cuts in other places, such as delaying flood hardening of streamgages, not upgrading equipment as planned, and not installing planned streamgages requested for flood forecasting. Additionally, other Federal, state and local agencies have provided temporary funding to continue some streamgages through the end of FY13 (9/30). These mitigating factors are interim measures.
In selecting streamgages to be discontinued the USGS sought to preserve streamgages that are legally required (those that support administration of interstate compacts, international treaties, and Supreme Court decrees); protect life and property (used in river forecasts and warnings); and provide long-term monitoring for assessing the effects of land use and climate change.”
